# Ethos-U NPU timing adapter initialization library #
#########################################################
# Timing adapter component is only available on certain implementations
# on FPGA and FVP where it is necessary to run bandwidth and latency
# sweeps on the Arm Ethos-U NPUs. The wrapper library here provides an
# easy way to add initialisation of the timing adapter block.
