Description

Mirrored EV-side tensor ABI used to communicate with EV74 kernels.

This header captures a candidate common ABI for EV kernels so host and firmware can converge on a single tensor/storage contract instead of per-graph ad hoc structs. It is currently a draft proposal — not yet wired into the live EV runtime — but it documents the shape of the per-op config blocks (tess, detess, quantize/dequantize, detessdequant, preproc) and the shared tensor/storage descriptor types they all reference.

The header is C-callable so firmware-side code can include it directly. All values are POD; layout is fixed by the structs themselves.
