Microarchitectural manual here.

This repository contains the Chisel source RTL for the Saturn Vector Unit, a parameterized RVV 1.0 vector unit. Saturn supports the entire RVV 1.0 application-profile specification, including

• V-extension (Full application-profile V)
• Zve64d - supports FP64, ELEN=64
• Zvfh - supports FP16
• Zvbb - support basic vector bit manipulation
• Zvl64/128/256/512/1024 - configurable VLEN
• Indexed/strided/segmented loads and stores
• Virtual memory with precise traps
• Full chaining with zero dead-time
• Configurable SIMD datapath width (64/128/256/512+)

This repository cannot be used stand-alone. Saturn is intended to be used to generate vector-enabled RISC-V cores and SoCs through the Chipyard SoC design framework.
