the original high performance and small footprint SoC based on Migen

[> Features

• Multiple CPU options:
  • VexRiscV.
  • mor1kx (a better OpenRISC implementation).
  • LatticeMico32, modified to include an optional MMU (experimental).
• Supports SDR, DDR, LPDDR, DDR2 and DDR3.
• Provided peripherals: UART, GPIO, timer, NOR flash controller, SPI flash controller, Ethernet MAC, and more.
• High performance: on Kintex-7, 125MHz system clock frequencies, 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 targets for a few boards. Support for other boards can easily be added as external modules.
