[> Milkymist-NG system-on-chip
------------------------------

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

The Milkymist-NG SoC supports the Milkymist One board. Obtain yours from:
  http://milkymist.org

Note that the -NG version is still experimental work in progress. For the
production version of Milkymist SoC, visit:
  https://github.com/milkymist/milkymist

[> Instructions
---------------
First, download and install Migen from:
  https://github.com/milkymist/migen

Once this is done, build the bitstream with:
  make
This will generate the build/soc.bit programming file.

The SoC expects a bootloader to be located in flash at 0x860000, just
like the legacy SoC did. However, there is no binary compatibility and a
new BIOS needs to be built and flashed for the -NG SoC.

You can find the source code of a compatible BIOS in the software/bios
directory. It compiles with Clang and LLVM by default, and you can find
the modified version with support for LM32 at:
  https://github.com/milkymist/llvm-lm32
  https://github.com/milkymist/clang-lm32

Enjoy!
