Vela

Vela is a lightweight, scalar-controlled vector coprocessor for VexRiscv, built in SpinalHDL as a foundation for composable tensor acceleration.

Current Status

Vela is still experimental. It is a working hardware lab, not a finished product platform.

• Vela v1 already has a documented ISA baseline in vela-isa-spec-v1
• Vela v1 also has a documented microarchitecture baseline in vela-uarch-spec-v1
• The current RTL generation entry point is sbt "runMain vela.GenVela"
• Vela is built around a lightweight vector ISA inspired by RVV, but full RVV compatibility is not the goal

Quick Start

This repo is based on Spinal Template Sbt

Generate the current Vela RTL:

sbt "runMain vela.GenVela"
