Activity Log:

• Run Doom on CPU

• POC IPU modifies frame buffer every frame

• Create IPU hooks for key methods like G_Ticker, G_Responder so IPU can step time and respond to keypresses

• Move level geometry to IPU on level load

• Implement all methods used by the automap (vector rendering, sprite rendering, AM event responder)

• Automap disabled on CPU, runs and renders entirely on IPU! (enabling CPU to continue raycasting to update map)

  

• Either implement coroutines in x86 to allow further dev on IPUModel, or implement frame streaming to local machine to allow dev on remote IPU

• Move core game loop to IPU as a coroutine, triggering CPU callbacks every tic to do unimplemented work

• Continue implementing main game systems on IPU...
