SpacemiT CPUs

This section explains how to use sherpa-onnx with the SpacemiT execution provider on SpacemiT RISC-V CPUs.

At the moment, this section is a starter skeleton. We focus on the following topics first:

• Building sherpa-onnx with SpacemiT provider enabled

• Running ASR and TTS examples with --provider=spacemit

• Using a provider config file through --provider=spacemit:path/to/config

The current build and example commands in this section are based on the existing sherpa-onnx build scripts and CI workflow.

The following boards are known to work:

• SpacemiT K1(Keystone X60+A60)

• SpacemiT K3(Keystone X100+A100)

• Another board with a SpacemiT RISC-V CPU (to be added later)
