   2 ------------------------------
   3
   4 This is the next-generation Milkymist(tm) system-on-chip design,
   5 introducing two key innovations:
   6  * Built on the powerful Migen VLSI logic design system.
   7  * Increased system memory performance thanks to a new architecture
   8    (ASMI) containing a transaction-reordering and superscalar controller.

  10 The Milkymist-NG SoC supports the Milkymist One board. Obtain yours from:
  11   http://milkymist.org
  12
  13 Note that the -NG version is still experimental work in progress. For the
  14 production version of Milkymist SoC, visit:

  17 [> Instructions
  18 ---------------
  19 First, download and install Migen from:
  20   https://github.com/milkymist/migen
  21
  22 Once this is done, build the bitstream with:
  23   python3 build.py
  24 This will generate the build/soc.bit programming file.
  25
  26 The SoC expects a bootloader to be located in flash at 0x860000, just
  27 like the legacy SoC did. However, there is no binary compatibility and a
  28 new BIOS needs to be built and flashed for the -NG SoC.
  29
  30 You can find the source code of a compatible BIOS in the software/bios
  31 directory. It compiles with Clang and LLVM by default, and you can find
  32 the modified version with support for LM32 at:
  33   https://github.com/milkymist/llvm-lm32
  34   https://github.com/milkymist/clang-lm32
  35
  36 Enjoy!
