| Saturn | ||
| ======== | ||
|
|
||
| Saturn is a parameterized RISC-V Vector Unit generator currently supporting integration with the Rocket and Shuttle cores. | ||
| Saturn implements a compact short-vector-length vector microarchitecture suitable for deployment in a DSP-optimized core or area-efficient general-purpose core. | ||
|
|
||
| More documentation on Saturn will be released in the future. | ||
|
|
||
| * Full support for `V` application-profile RVV 1.0 | ||
| * Precise traps with virtual memory | ||
| * Indexed/strided/segmented loads and stores | ||
| * Mask operations | ||
| * Register-gather + reductions | ||
| * `Zvfh` support for vector half-precision floating-point (FP16) | ||
| * `Zve64d` support for vector FP32 and FP64 | ||
| * Configurable vector length, from `Zvl64b` up (tested to `Zvl4096b`) | ||
| * Configurable datapath width, from 64b up (tested to 512b) | ||
