Abstract
An image processing system for convolving an image includes processing circuitry that is configured to retrieve the image including a set of rows, a merged kernel, multiple skip values and a pixel base address. The merged kernel includes all non-zero coefficients of a set of kernels. Each skip value corresponds to a location offset of each non-zero coefficient with respect to a previous non-zero coefficient. Further, the processing circuitry is configured to execute a multiply-accumulate (MAC) instruction and a load instruction parallelly in one clock cycle for multiple times, on the set of rows and the merged kernel to convolve the image with the merged kernel. Each row on which the MAC and load instructions are executed is associated with a corresponding non-zero coefficient and a corresponding skip value. The load instruction is executed based on the pixel base address, the corresponding skip value, and a width of each row.
