+TLM-1.0 header files
+====================
+
+Dir: include/tlm_core/tlm_1/
+
+SubDirs: tlm_analysis/
+ tlm_req_rsp/
+
+Files: README.txt
+
+
+Comments
+========
+
+User code should only #include the tlm or tlm.h header file in the include/
+directory and avoid including any of the include files in this directory
+directly. All objects defined in this file hierarchy are in the tlm namespace.
+
+The header files are organizated, by subdirectory, as follows:
+
+
+tlm_analysis/
+--------------
+
+This contains the analysis interfaces, ports, and fifos. These files were not
+part of the original TLM-1.0 release, but have been grouped with TLM-1.0 in this
+release of TLM-2.0
+
+Files:
+ tlm_analysis.h (includes the other header files in this directory )
+ tlm_analysis_fifo.h (defines tlm_analysis_fifo )
+ tlm_analysis_if.h (defines tlm_analysis_if and tlm_delayed_analysis_if )
+ tlm_analysis_port.h (defines tlm_analysis_port )
+ tlm_analysis_triple.h (defines tlm_analysis_triple )
+ tlm_write_if.h (defines tlm_write_if and tlm_delayed_write_if )
+
+
+tlm_req_rsp/
+------------
+
+This provides support for TLM modeling based on a request/response pair that
+are passed by value. This is the original TLM 1.0 standard, with the addition
+of an overloading of the blocking transport method with pass-by-reference arguments.
+
+Files:
+ tlm_req_rsp.h (includes the key header files from the other directories)
+
+ tlm_1_interfaces/
+ tlm_core_ifs.h (defines the TLM 1.0 core interfaces:
+ tlm_transport_if
+ tlm_blocking_get_if
+ tlm_blocking_put_if
+ tlm_nonblocking_get_if
+ tlm_nonblocking_put_if
+ tlm_get_if
+ tlm_put_if
+ tlm_blocking_peek_if
+ tlm_nonblocking_peek_if
+ tlm_peek_if
+ tlm_blocking_get_peek_if
+ tlm_nonblocking_get_peek_if
+ tlm_get_peek_if )
+ tlm_fifo_ifs.h ( defines the TLM1.0 fifo interfaces:
+ tlm_fifo_debug_if
+ tlm_fifo_put_if
+ tlm_fifo_get_if
+ tlm_fifo_config_size_if )
+ tlm_master_slave_ifs.h ( defines the TLM1.0 master slave interfaces:
+ tlm_blocking_master_if
+ tlm_blocking_slave_if
+ tlm_nonblocking_master_if
+ tlm_nonblocking_slave_if
+ tlm_master_if
+ tlm_slave_if )
+ tlm_tag.h ( defines tlm_tag )
+
+ tlm_ports/
+ tlm_nonblocking_port.h (defines tlm_nonblocking_put_port,
+ tlm_nonblocking_get_port and
+ tlm_nonblocking_peek_port )
+ tlm_event_finder.h (defines tlm_event_finder_t )
+
+ tlm_channels/
+ tlm_fifo/
+ tlm_fifo.h (defines tlm_fifo, includes the other files )
+ tlm_fifo_peek.h (defines peek and poke interfaces for tlm_fifo )
+ tlm_fifo_put_get.h (defines put and get interfaces for tlm_fifo )
+ tlm_fifo_resize.h (defines expand, reduce, bound and unbound
+ interfaces for tlm_fifo )
+ circular_buffer.h (defines circular buffer used by tlm_fifo )
+ tlm_req_rsp_channels/
+ tlm_req_rsp_channels.h (defines tlm_req_rsp_channel and
+ tlm_transport_channel )
+ tlm_put_get_imp.h (contains implementatins used by the channels)
+
+ tlm_adapters/
+ tlm_adapters.h (defines transport_to_master and tlm_slave_to_transport)

+
+
+Comments
+========
+
+User code should only #include the tlm or tlm.h header file in the include/
+directory and avoid including any of the include files in this directory
+directly. All objects defined in this file hierarchy are in the tlm namespace.
+
+tlm_version.h contains the definitions for the version string and integer values
+
+The header files are organizated, by subdirectory, as follows:
+
+
+tlm_2_interfaces/
+-----------------
+
+Contains the TLM-2.0 core interfaces
+
+Files:
+ tlm_2_interfaces.h (includes the other header files in this directory )
+ tlm_fw_bw_ifs.h (defines the TLM 2.0 interface API's:
+ tlm_fw_nonblocking_transport_if
+ tlm_bw_nonblocking_transport_if
+ tlm_blocking_transport_if
+ tlm_fw_direct_mem_if
+ tlm_bw_direct_mem_if
+ tlm_transport_dbg_if
+ the enumeration type
+ tlm_sync_enum
+ and the TLM 2.0 standard interfaces using the API's
+ tlm_fw_transport_if
+ tlm_bw_transport_if )
+ tlm_dmi.h (defines tlm_dmi)
+
+
+tlm_generic_payload/
+--------------------
+
+Contains the TLM-2.0 generic payload and associated classes and helper functions
+
+Files:
+ tlm_generic_payload.h ( includes the other header files in this directory)
+ tlm_gp.h (defines the TLM 2.0 generic payload classes:
+ tlm_generic_payload
+ tlm_extension
+ tlm_extension_base
+ tlm_mm_interface
+ and the enumeration types
+ tlm_command
+ tlm_response_status )
+ tlm_array.h (defines array class used by the extention
+ mechanism )
+ tlm_endian_conv.h (defines the implementation for the endianness
+ helper functions:
+ tlm_to_hostendian_generic()
+ tlm_from_hostendian_generic()
+ tlm_to_hostendian_word()
+ tlm_from_hostendian_word()
+ tlm_to_hostendian_aligned()
+ tlm_from_hostendian_aligned()
+ tlm_to_hostendian_single()
+ tlm_from_hostendian_single() )
+
+ tlm_helpers.h (defines the helper functions to determine the
+ hostendianness:
+ get_host_endianness()
+ host_has_little_endianness()
+ has_host_endianness()
+ and defines the enumeration type:
+ tlm_endianness
+ tlm_phase.h (defines tlm_phase as an extendable enum type)
+
+
+tlm_sockets/
+------------
+
+Contains the standard TLM-2.0 initiator and target sockets (which are used as
+the base classes for the convenience sockets in tlm_utils)
+
+Files:
+ tlm_sockets.h (includes the other header files in this directory)
+ tlm_initiator_socket.h (defines the initiator sockets:
+ tlm_initiator_socket_base
+ tlm_initiator_socket_b
+ tlm_initiator_socket
+ tlm_target_socket.h (defines the target sockets:
+ tlm_target_socket_base
+ tlm_target_socket_b
+ tlm_target_socket
+
+
+tlm_quantum/
+------------
+This contains the global quantum. (The quantum keeper is in tlm_utils)
+
+Files:
+ tlm_quantum.h ( includes the other header file in this directory )
+ tlm_global_quantum.h ( defines tlm_global_quantum )

+// can call the get_direct_mem_ptr method with the 'trans' parameter set to
+// the address that it wants to gain access to. It sets the trans.m_command
+// to specify if the initiator intended use (read or write)
+// to the target's DMI region. The initiator is responsible for calling the
+// method with a freshly initialized tlm_dmi object either by using a newly
+// constructed object, or by calling an existing object's init() method.
+// - Although a reference to a complete 'TRANS' type is passed to the get_
+// direct_mem_ptr call, only the address command, and extension fields are of
+// interest in most cases.
+// - Read and write ranges are not necessarily identical. If they are, a target
+// can specify that the range is valid for all accesses with the tlm_data
+// m_type attribute in the.
+// - The interconnect, if any, needs to decode the address and forward the
+// call to the corresponding target. It needs to handle the address exactly
+// as the target would expect on a transaction call, e.g. mask the address
+// according to the target's address width.
+// - If the target supports DMI access for the given address, it sets the
+// data fields in the DMI struct and returns true.
+// - If a target does not support DMI access it needs to return false.
+// The target can either set the correct address range in the DMI struct
+// to indicate the memory region where DMI is disallowed, or it can specify
+// the complete address range if it doesn't know it's memory range. In this
+// case the interconnect is responsible for clipping the address range to
+// the correct range that the target serves.
+// - The interconnect must always translate the addresses to the initiator's
+// address space. This must be the inverse operation of what the
+// interconnect needed to do when forwarding the call. In case the
+// component wants to change any member of the tlm_dmi object, e.g. for
+// its own latency to the target's latency, it must only do so *after* the
+// target has been called. The target is always allowed to overwrite all
+// values in the tlm_dmi object.
+// - In case the slave returned with an invalid region the bus/interconnect
+// must fill in the complete address region for the particular slave in the
+// DMI data structure.
+//
+// DMI hint optimization:
+//
+// Initiators may use the DMI hint in the tlm_generic_payload to avoid
+// unnecessary DMI attempts. The recommended sequence of interface
+// method calls would be:
+//
+// - The initiator first tries to check if it has a valid DMI region for the
+// address that it wants to access next.
+// - If not, it performs a normal transaction.
+// - If the DMI hint in this transaction is true, the initiator can try and
+// get the DMI region.
+//
+// Note that the DMI hint optimization is completely optional and every
+// initiator model is free to ignore the DMI hint. However, a target is
+// required to set the DMI hint to true if a DMI request on the given address
+// with the given transaction type (read or write) would have succeeded.

+// that it already reported, if it would answer the same DMI request
+// with any member of the tlm_dmi data structure set differently.
+// - An interconnect component must forward the invalidate_direct_mem_ptr call
+// to all initiators that could potentially have a DMI pointer to the region
+// specified in the method arguments. A safe implementation is to call
+// every attached initiator.
+// - An interconnect component must transform the address region of an

+Tranaction-Level Modelling
+Endianness Helper Functions
+
+DESCRIPTION
+A set of functions for helping users to get the endianness
+right in their TLM models of system initiators. These functions are
+for use within an initiator. They can not be used as-is outside
+an initiator because the extension used to store context will not work
+if cascaded, and they do not respect the generic payload mutability
+rules. However this code may be easily copied and adapted for use
+in bridges, etc..
+
+These functions are not compulsory. There are other legitimate ways to
+achieve the same functionality. If extra information is available at
+compile time about the nature of an initiator's transactions, this can
+be exploited to accelerate simulations by creating further functions
+similar to those in this file. In general a functional transaction can be
+described in more than one way by a TLM-2 GP object.
+
+The functions convert the endianness of a GP object, either on request or
+response. They should only be used when the initiator's endianness
+does not match the host's endianness. They assume 'arithmetic mode'
+meaning that within a data word the byte order is always host-endian.
+For non-arithmetic mode initiators they can be used with a data word
+size of 1 byte.
+
+All the functions are templates, for example:
+
+template<class DATAWORD> inline void
+ to_hostendian_generic(tlm_generic_payload *txn, int sizeof_databus)
+
+The template parameter provides the data word width. Having this as a class
+makes it easy to use it for copy and swap operations within the functions.
+If the assignment operator for this class is overloaded, the endianness
+conversion function may not have the desired effect.
+
+All the functions have the same signature except for different names.
+
+The principle is that a function to_hostendian_convtype() is called when the
+initiator-endian transaction is created, and the matching function
+from_hostendian_convtype() is called when the transaction is completed, for
+example before read data can be used. In some cases the from_ function is
+redundant but an empty function is provided anyway. It is strongly
+recommended that the from_ function is called, in case it ceases to be
+redundant in future versions of this code.
+
+No context needs to be managed outside the two functions, except that they
+must be called with the same template parameter and the same bus width.
+
+For initiator models that can not easily manage this context information,
+a single entry point for the from_ function is provided, which will be
+a little slower than calling the correct from_ function directly, as
+it can not be inlined.
+
+All functions assume power-of-2 bus and data word widths.
+
+Functions offered:
+
+0) A pair of functions that work for almost all TLM2 GP transactions. The
+only limitations are that data and bus widths should be powers of 2, and that
+the data length should be an integer number of streaming widths and that the
+streaming width should be an integer number of data words.
+These functions always allocate new data and byte enable buffers and copy
+data one byte at a time.
+ tlm_to_hostendian_generic(tlm_generic_payload *txn, int sizeof_databus)
+ tlm_from_hostendian_generic(tlm_generic_payload *txn, int sizeof_databus)
+
+1) A pair of functions that work for all transactions regardless of data and
+bus data sizes and address alignment except for the the following
+limitations:
+- byte-enables are supported only when byte-enable granularity is no finer
+than the data word (every data word is wholly enabled or wholly disabled)
+- byte-enable-length is not supported (if byte enables are present, the byte
+enable length must be equal to the data length).
+- streaming width is not supported
+- data word wider than bus word is not supported
+A new data buffer and a new byte enable buffer are always allocated. Byte
+enables are assumed to be needed even if not required for the original
+(unconverted) transaction. Data is copied to the new buffer on request
+(for writes) or on response (for reads). Copies are done word-by-word
+where possible.
+ tlm_to_hostendian_word(tlm_generic_payload *txn, int sizeof_databus)
+ tlm_from_hostendian_word(tlm_generic_payload *txn, int sizeof_databus)
+
+2) If the original transaction is both word and bus-aligned then this pair of
+functions can be used. It will complete faster than the generic function
+because the data reordering function is much simpler and no address
+conversion is required.
+The following limitations apply:
+- byte-enables are supported only when byte-enable granularity is no finer
+than the data word (every data word is wholly enabled or wholly disabled)
+- byte-enable-length is not supported (if byte enables are present, the byte
+enable length must be equal to the data length).
+- streaming width is not supported
+- data word wider than bus word is not supported
+- the transaction must be an integer number of bus words
+- the address must be aligned to the bus width
+ tlm_to_hostendian_aligned(tlm_generic_payload *txn, int sizeof_databus)
+ tlm_from_hostendian_aligned(tlm_generic_payload *txn, int sizeof_databus)
+
+3) For single word transactions that don't cross a bus word boundary it
+is always safe to work in-place and the conversion is very simple. Again,
+streaming width and byte-enable length are not supported, and byte-enables
+may not changes within a data word.
+ tlm_to_hostendian_single(tlm_generic_payload *txn, int sizeof_databus)
+ tlm_from_hostendian_single(tlm_generic_payload *txn, int sizeof_databus)
+
+4) A single entry point for accessing the correct from_ function without
+needing to store context.

+Comments
+========
+
+This directory contains a number of ease-of-use and convenience implementations
+for the interoperability standard. All objects defined in the header files of
+this directory are contained in the tlm_util namespace.
+There is no tlm_utils.h header files containing all includes in order to avoid
+additional dependencies for TLM 2.0
+
+Files:
+ simple_initiator_socket.h
+ version of an initiator socket that has a default implementation of all
+ interfaces and allows to register an implementation for any of the
+ interfaces to the socket, either unique interfaces or tagged interfaces
+ (carrying an additional id)
+
+ simple_target_socket.h
+ version of a target socket that has a default implementation of all
+ interfaces and allows to register an implementation for any of the
+ interfaces to the socket, either unique interfaces or tagged interfaces
+ (carrying an additional id)
+ This socket allows to register only 1 of the transport interfaces
+ (blocking or non-blocking) and implements a conversion in case the
+ socket is used on the other interface
+
+ passthrough_target_socket.h
+ version of a target socket that has a default implementation of all
+ interfaces and allows to register an implementation for any of the
+ interfaces to the socket.
+
+ multi_passthrough_initiator_socket.h
+ an implementation of a socket that allows to bind multiple targets to the
+ same initiator socket. Implements a mechanism to allow to identify in the
+ backward path through which index of the socket the call passed through
+
+ multi_passthrough_target_socket.h
+ an implementation of a socket that allows to bind multiple initiators to
+ the same target socket. Implements a mechanism to allow to identify in the
+ forward path through which index of the socket the call passed through
+
+ multi_socket_bases.h
+ contains base class definitions used by the multi_passthrough sockets
+
+ peq_with_get.h
+ payload event queue (PEQ) implementation using a pull interface.
+ Has a get_next_transaction API that returns the transaction that is
+ scheduled in the event queue
+
+ peq_with_cb_and_phase.h
+ another payload event queue, this one with a push interface (callback
+ mechanism ). Allows to register a callback that will be called whenever
+ the event in the event queue is triggered, the callback gets transaction
+ and phase as arguments
+
+ instance_specific_extensions.h
+ is an implementation for adding extentions in the generic payload that
+ are specific to an instance along the path of a transaction, to allow that
+ extentions of the same type can be used by the different blocks along
+ the path of the transaction
+
+ tlm_quantumkeeper.h
+ is an convenience object used to keep track of the local time in
+ an initiator (how much it has run ahead of the SystemC time), to
+ synchronize with SystemC time etc.

+/*
+Instance specific extensions, are extension that only a single instance of a module
+may access. They are invisible to all other modules; they are private to this
+instance so to speak.
+
+As they are only of value to a certain instance, this instance knows very well
+when it needs them and when it does not need them any longer (usually when
+a transaction passes through a module for the last time).
+It does not have to care if anyone else in the system may still have a
+reference to the transaction as this one is not able to access the extension
+anyway.
+Therefore the instance is obliged to call set_extension when it wants to add a
+private extension and clear_extension when it does not need it any more.
+
+To get access to an instance specifc extension the module must own a so called
+instance_specific_extension_accessor that provides the exclusive access rights.
+Assuming the instance_specific_extension_accessor of a given module is called m_accessor
+and the transaction of which the private extension is about to be accessed
+is called txn, then the calls have to be
+
+m_accessor(txn).set_extension(...);
+or
+m_accessor(txn).clear_extension(...);
+
+The owner of the private extension is responsible to allocate/deallocate
+the extension before/after setting/clearing the extension.
