30 [> Description
31 --------------
32 First release of LiteX and the ecosystem of cores!
33
34 LiteX is a Migen/MiSoC based Core/SoC builder that provides the infrastructure to easily create
35 Cores/SoCs (with or without CPU).
36
37 The common components of a SoC are provided directly:
38 - Buses and Streams (Wishbone, AXI, Avalon-ST)
39 - Interconnect
40 - Common cores (RAM, ROM, Timer, UART, etc...)
41 - CPU wrappers/integration
42 - etc...
43 And SoC creation capabilities can be greatly extended with the ecosystem of LiteX cores (DRAM,
44 PCIe, Ethernet, SATA, etc...) that can be integrated/simulated/build easily with LiteX.
45
46 It also provides build backends for open-source and vendors toolchains.
