Bharathi’s Status Report for 4/12/25

Accomplished

DMG PPU (4-color PPU)

Spent a lot of time debugging the many edge cases part of the DMG Acid Test. DMG PPU pretty close to being done and looks almost perfect: 

DMG Acid Test — Fully Integrated Version
DMG Acid Test — Reference Image

CGB PPU (full-color PPU)

No updates here.

APU / CODEC Research

  • Acquired 3.5mm TRS connector for testing on APU.
  • Discussed the APU design / implementation with Ruslana.
  • Researched audio output for APU.

Summary of time spent this week

  • Integration debugging: 20+ hrs
  • APU / Audio research: 2+ hrs
  • DMG Acid Test debugging: 10+ hrs

Schedule / Progress

I believe I’m on schedule and integration going well. We spent a lot of time debugging on simulation and we’ve made great progress fixing a number of different bugs across our design. Our next goal as a group would be get something that is moderately playable by next week.

Next Step(s)

  • More integration debugging (this time on FPGA).
  • Final presentation stuff.
  • APU test on FPGA.

Verification & Validation information is part of our Team Status Report.
