GLINT R4 Stripe Interleaving

Rasterizer #2 ( )

Rasterizer #1

Rasterizer #2

Only a fraction of polygons are processed by both Rasterizers

Rasterizer #1 ( )

Both ( )

Efficient use of multiple rasterizers

Rasterizers process interleaved Stripes on the screen
- 4,8,16 scan lines
Multiplies peak fill-rate through parallel pixel processing
- Striping gives better texture cache coherency than scanline interleaving
Increases polygon throughput through distributed geometry processing
- Each processor lights and sets up only the polygons that touch its stripes
