The Saturn Vector Unit

====================================



Microarchitectural manual [here](https://saturn-vectors.org/).

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+)

Using Saturn

-------------

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](https://github.com/ucb-bar/chipyard) SoC design framework.
