GIF[edit | edit source]
The GIF sends textures and geometry to the GS. It takes data from three different PATHs:
- PATH1: VU1 via XGKICK instruction. Highest priority.
- PATH2: VIF1 via DIRECT/DIRECTHL. Medium priority.
- PATH3: GIF DMAC channel (channel 2). Lowest priority.
Only one PATH may run at a time. Under normal conditions, when one PATH stops, the highest priority queued PATH will begin transfer.
