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.
