Tensor DMA engine
Maturity simulatedTargets FPGA + ASICDifficulty MediumPriority 1
N-dimensional strided DMA with on-the-fly transpose, im2col, padding and broadcast for moving tensors between DRAM and accelerator SRAM.
Simulated. The RTL is lint clean and passes its self-checking testbench against a reference model in simulation. It has not been run on an FPGA board or in silicon.
