VAX 6000 Series Vector Processor
The FV64A chipset consists of five core chips, as follows:
• Vector instruction issue and scalar/vector interface chip
• Vector register file chip, 4 chips
• Vector arithmetic data path, floating-point unit (FPU) chip, 4 chips
• Load/Store—Vector module translation buffer, cache, and XMI
interface controller chip
• Clock generation chip (same as on scalar module)
