Ethos-U55

Ethos-U55 is a micro Neural Processing Unit coprocessor to accelerate machine learning inference with a 
configurable 32 to 256 multiply-accumulate (MAC) engine. One of the features to minimise memory use is that weights are losslessly compressed as part of a compiled command stream with the unit undertaking weight decompression. The unit executes the command stream with local DMA access to system memory.
