A high performance and small footprint system-on-chip design based on Migen.
|
||||
a high performance and small footprint SoC based on Migen
|
||||
|
||||
MiSoC supports the Mixxeo and the Milkymist One.
|
||||
Obtain your development system at http://m-labs.hk
|
||||
|
||||
[> Instructions (software)
|
||||
--------------------------
|
||||
1. Compile and install binutils. Take the latest version from GNU.
|
||||
[> 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.
|
||||
|
||||
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
|
||||
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
|
||||
|
||||
The second command requires m1nor-ng, FJMEM and UrJTAG.
|
||||
These tools can be found at:
|
||||
https://github.com/m-labs/fjmem-m1
|
||||
http://urjtag.org
|
||||
|
||||
[> Instructions (gateware)
|
||||
--------------------------
|
||||
First, download and install Migen from:
|
||||
https://github.com/m-labs/migen
|
||||
8. Run a terminal program on the board's serial port at 115200 8-N-1.
|
||||
You should get the BIOS prompt.
|
||||
|
||||
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.
|
||||
|
||||
A new BIOS needs to be built and flashed for MiSoC.
|
||||
There is no compatibility with Milkymist SoC.
|
||||
|
||||
Enjoy!
