NEURAL NETWORK PROCESSOR USING COMPRESSION AND DECOMPRESSION OF ACTIVATION DATA TO REDUCE MEMORY BANDWIDTH UTILIZATION

A deep neural network ("DNN") module can compress and decompress neuron-generated activation data to reduce the utilization of memory bus bandwidth. The compression unit can receive an uncompressed chunk of data generated by a neuron in the DNN module. The compression unit generates a mask portion and a data portion of a compressed output chunk. The mask portion encodes the presence and location of the zero and non-zero bytes in the uncompressed chunk of data. The data portion stores truncated non-zero bytes from the uncompressed chunk of data. A decompression unit can receive a compressed chunk of data from memory in the DNN processor or memory of an application host. The decompression unit decompresses the compressed chunk of data using the mask portion and the data portion. This can reduce memory bus utilization, allow a DNN module to complete processing operations more quickly, and reduce power consumption.

To save battery life, such a device remains in a low power mode and is awakened for commissioning, for example, by a button press (e.g. for a wall switch) or motion or audio sensing (e.g. for an occupancy sensor or the like). When awakened, the lighting control device enters its commissioning mode with the radio transceiver active for a short period of time. If the lighting control device is not commissioned within that time interval, for example, it may reenter the sleep mode. Conversely, if successfully commissioned during the active time period, the lighting control device is ready for normal operations.
