Emotion Engine
- Behavioral Synthesis from so much floating point power ??
- Superscalar core - dual-issue, 128-bit SIMD + scalar fpu
- VPU0- 4 FMACs, 1FDIV
- VPU1 - for lighting and geometry - 4 FMACs, 1FDIV, + EFU
- 128 bits => 4 32bit operations at once or 16 8-bit operations
2.4Gbytes/s bandwidth for bus
