Simple SoC

Description

A very basic, custom SoC softcore



Primary git repo: on github

Specs/Design: on github as well

We'll merely keep a meetup log and notes here, important stuff will be stored in One Single Repo (tm), next to the code :)

Meetups

Upcoming

2013/10/23 - We love glitches

  • Fix core/vram/vga to get some real video output!
  • See if we can fit the vram by resizing things?

Log

2013/10/16 - How about conditions?

  • Implemented beq, bga, bgt, jr, draw, fix write16, read16
  • wires up vram (resized to 2bpp because it doesn't fit)
  • added vga output, but it is glitched/buggy

2013/10/09 - Howdy Simulator, for real

  • debug, debug, debug, and simulate
  • Implemented more state logic
  • cpu mostly works, needs some more opcodes!

2013/10/02 - Howdy Simulator

  • Implemented ram
  • Added delays for ram

2013/09/25 - Verilog at last

  • Spec now has vsync
  • Reviewed sdlcore code
  • Hacked together some very basic Verilog

2013/09/18 - Let there be code

  • Debugged & Finished sdlcore implementation

2013/09/11 - September reunion

  • Discuss and improve specs a bit
  • Update documentation and C# ref. implementation
