-This is the next-generation Milkymist(tm) system-on-chip design,
-introducing two key features:
- * Built on the powerful Migen VLSI logic design system.
- * Increased system memory performance thanks to LASMI.
+a high performance and small footprint SoC based on Migen
-This translates to more development productivity, better video resolution
-and quality, ease of designing complex hardware accelerators, and much
-more flexibility in hardware designs.
-The milkymist-ng SoC supports the Mixxeo and the Milkymist One.

+[> Features
+-----------
+ * LatticeMico32 CPU, modified to include an optional MMU (experimental).
+ * High performance memory controller capable of issuing several SDRAM commands
+ per FPGA cycle.
+ * Supports SDR, DDR, LPDDR and DDR2.
+ * Provided peripherals: UART, GPIO, timer, GPIO, NOR flash controller, SPI
+ flash controller, Ethernet MAC, and more.
+ * High performance: on Spartan-6, 83MHz system clock frequencies, 10+Gbps DDR
+ SDRAM bandwidth, 1080p 32bpp framebuffer, etc.
+ * Low resource usage: basic implementation fits easily in Spartan-6 LX9.
+ * Portable and easy to customize thanks to Python- and Migen-based
+ architecture.
+ * Design new peripherals using Migen and benefit from automatic CSR maps
+ and logic, etc.
+ * Possibility to encapsulate legacy Verilog/VHDL code.
-[> Instructions (software)
---------------------------
-1. Compile and install binutils. Take the latest version from GNU.
+MiSoC comes with built-in support for the following boards:
+ * Mixxeo, the digital video mixer from M-Labs [XC6SLX45]
+ * Milkymist One, the original M-Labs video synthesizer [XC6SLX45]
+ * Papilio Pro, a simple and low-cost development board [XC6SLX9]
+MiSoC is portable and support for other boards can easily be added as external
+modules.
+
+[> Quick start guide
+--------------------
+1. Install Python 3.3+, Migen and FPGA vendor's development tools.
+ Get Migen from: https://github.com/m-labs/migen
+
+2. Install JTAG tools.
+ For Mixxeo and M1: http://urjtag.org
+ For Papilio Pro: http://xc3sprog.sourceforge.net
+
+3. Obtain and build any required flash proxy bitstreams. Flash proxy bitstreams
+ give JTAG access to a flash chip through the FPGA.
+ For Mixxeo and M1: https://github.com/m-labs/fjmem-m1
+ For Papilio Pro: https://github.com/GadgetFactory/Papilio-Loader
+ (xc3sprog/trunk/bscan_spi/bscan_spi_lx9_papilio.bit)
+
+4. Compile and install binutils. Take the latest version from GNU.
mkdir build && cd build
../configure --target=lm32-elf
make
make install
-2. Compile and install GCC 4.5. Take gcc-core and gcc-g++ from GNU.
+5. Compile and install GCC 4.5. Take gcc-core and gcc-g++ from GNU.
rm -rf libstdc++-v3
mkdir build && cd build
../configure --target=lm32-elf --enable-languages="c,c++" --disable-libgcc --disable-libssp
make
make install
-3. Obtain compiler-rt and set the CRTDIR environment variable to the root of
- its source tree.
+6. Obtain compiler-rt and set the CRTDIR environment variable to the root of
+ its source tree.
svn co http://llvm.org/svn/llvm-project/compiler-rt/trunk compiler-rt
export CRTDIR=/path_to/compiler-rt
-4. Build and flash the BIOS (part of this source distribution).
- cd software/bios
- make
- make flash
-
-The second command requires m1nor, FJMEM and UrJTAG.
-These tools can be found at:
- https://github.com/milkymist/fjmem-m1
- http://urjtag.org
-
-[> Instructions (gateware)
---------------------------
-First, download and install Migen from:
- https://github.com/milkymist/migen
-
-Once this is done, build the bitstream with:
- ./make.py [-p <platform>] -l
-This will generate the build/soc-<platform>.bit programming file
-and load it with UrJTAG.
+7. Build and flash the BIOS and bitstream. Run from MiSoC:
+ For Mixxeo: ./make.py all
+ For M1: ./make.py -p m1 -s FramebufferSoC all
+ For Papilio Pro: ./make.py -t simple all
-A new BIOS needs to be built and flashed for the -ng SoC.
+8. Run a terminal program on the board's serial port at 115200 8-N-1.
+ You should get the BIOS prompt.
-Enjoy!
+9. Read and experiment with the source!
+ Come to our IRC channel and mailing list!
