|
|
|
a high performance and small footprint SoC based on Migen
|
|
|
|
|
|
[> Features
|
|
-----------
|
|
* LatticeMico32 CPU, modified to include an optional MMU (experimental).
|
|
* mor1kx (a better OpenRISC implementation) as alternative CPU option.
|
|
* High performance memory controller capable of issuing several SDRAM commands
|
|
per FPGA cycle.
|
|
* Supports SDR, DDR, LPDDR, DDR2 and DDR3.
|
|
* 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.
|
|
- on Kintex-7, 125MHz system clock frequencies (up to 200MHz without DDR3),
|
|
64Gbps DDR3 SDRAM bandwidth.
|
|
* 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.
|
|
|
|
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]
|
|
* KC705, a Kintex-7 devboard from Xilinx [XC7K325T]
|
|
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 and KC705: 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)
|
|
For KC705: https://github.com/m-labs/bscan_spi_kc705
|
|
|
|
4. Compile and install binutils. Take the latest version from GNU.
|
|
mkdir build && cd build
|
|
../configure --target=lm32-elf
|
|
make
|
|
make install
|
|
|
|
5. Compile and install GCC. Take gcc-core and gcc-g++ from GNU (version 4.5 or >=4.9).
|
|
rm -rf libstdc++-v3
|
|
mkdir build && cd build
|
|
../configure --target=lm32-elf --enable-languages="c,c++" --disable-libgcc --disable-libssp
|
|
make
|
|
make install
|
|
|
|
6. Build and flash the BIOS and bitstream. Run from MiSoC:
|
|
For Mixxeo: ./make.py all
|
|
For M1: ./make.py -p m1 all
|
|
For Papilio Pro: ./make.py -t ppro all
|
|
For KC705: ./make.py -t kc705 all
|
|
|
|
7. Run a terminal program on the board's serial port at 115200 8-N-1.
|
|
You should get the BIOS prompt.
|
|
|
|
8. Read and experiment with the source!
