Current EV74 inventory
Each native operation has a typed request, canonical admission, an allocation-independent host codec, device workers and operation-owned registration. Use the operation page for admitted tensors, ordered math and workspace; a family name alone does not establish dtype, layout or shape support.
| Operation | Device implementation | Numerical contract |
|---|---|---|
| Cast | cast/device (EV74/cast/device) | Scalar-format conversion |
| Dequant | dequant/device (EV74/dequant/device) | INT8 dequantization |
| Quant | quant/device (EV74/quant/device) | FP32/BF16/FP16 to INT8 |
| CastTess | casttess/device (EV74/casttess/device) | Conversion to MLA-tiled BF16 |
| QuantTess | quanttess/device (EV74/quanttess/device) | Quantization to MLA-tiled INT8 |
| DetessCast | detesscast/device (EV74/detesscast/device) | BF16 storage reconstruction and conversion |
| DetessDequant | detessdequant/device (EV74/detessdequant/device) | Tiled INT8 dequantization |
| Tess | tess/device (EV74/tess/device) | Bit-preserving tessellation |
| Detess | detess/device (EV74/detess/device) | Bit-preserving detessellation |
| Preproc | preproc/device (EV74/preproc/device) | Image sampling, color conversion and output packing |
| Histogram | histogram/device (EV74/histogram/device) | Intensity histograms |
| FAST | fast/device (EV74/fast/device) | Corner detection |
| FAST+BRIEF | fast_brief/device (EV74/fast_brief/device) | Corners and binary descriptors |
| Tracker | tracker/device (EV74/tracker/device) | Sparse point tracking |
Detection and tracking are distinct operations; compose FAST and Tracker when an application needs both. Native device controls are fixed-width wire contracts, not C++ plans or application configuration. Generated catalogue and capability checks select matching entries; firmware composition describes readable developer IDs and transport mapping.
For new work, follow the contribution guide. Record tensor roles, physical storage, arithmetic order, scratch bounds, DMA completion rules and independent tests. Do not copy the A65 support table as an EV74 contract.
