Update Cadence Xtensa backend docs using backend template #8533
Description
📚 The doc issue
Update the Cadence Xtensa backend top-level documentation page (docs/source/backends-coreml.md) to use the new backend template (docs/source/backend-template.md). See backend-xnnpack.md for an example. Feel free to deviate or suggest changes to the template if it does not make sense for this backend.
The template (docs/source/backend-template.md) includes the following information:
- Delegate features
- Development requirements
- Target requirements
- Partitioner API
- Quantization
- Runtime integration
General documentation guidelines that I'm hoping to follow:
- Leverage brief in-line code samples, where possible
- Keep things concise
- Avoid first person (I/we)
- I'm generally trying to follow https://developers.google.com/style/highlights
Suggest a potential alternative/fix
