of_acc_depthwise_conv
Depthwise and pointwise convolution unit
Maturity plannedTargets FPGA + ASICDifficulty MediumPriority 2
Engine optimised for depthwise separable convolutions with per-channel kernels and a fused pointwise stage, common in mobile networks.
Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.
Interfaces
| Port | Direction | Kind | Width | Notes |
|---|---|---|---|---|
| ctrl | in/out | AXI4-Lite control bus | 32 | Control and status registers, including ID, VERSION and STATUS |
| irq | out | interrupt | 1 | Interrupt request |
| ifm | in | AXI4-Stream | 128 | |
| ofm | out | AXI4-Stream | 128 |
