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...
