Processing group convolution in neural network processor
Embodiments relate to a neural processor circuit including neural engines, a buffer, and a kernel access circuit. The neural engines perform convolution operations on input data and kernel data to generate output data. The buffer is between the neural engines and a memory external to the neural processor circuit. The buffer stores input data for sending to the neural engines and output data received from the neural engines. The kernel access circuit receives one or more kernels from the memory external to the neural processor circuit. The neural processor circuit operates in one of multiple modes, at least one of which divides a convolution operation into multiple independent convolution operations for execution by the neural engines.
