Abstract
A reconfigurable convolution engine for performing a convolution operation on an image is disclosed. A data receiving module receives image data. A determination module determines a kernel size based on the image data, clock speed associated to the convolution engine and available on-chip resources. A generation module generates a plurality of instances based on the kernel size. A configuration module configures an adder engine comprising a plurality of adders configured to operate in a pipelined structure and in parallel with the plurality of instances. An execution module executes the convolution operation on each of the plurality of instances and the adder engine. A filtering module filters an output of the convolution operation by using a filter function configured to operate on a predefined threshold function.
