Abstract
Provided is an image recognition processor. The image recognition processor includes a plurality of nano cores arranged in rows and columns and configured to perform a pattern recognition operation on an input feature using a kernel coefficient in response to each instruction, an instruction memory configured to provide the instruction to each of the plurality of nano cores, a feature memory configured to provide the input feature to each of the plurality of nano cores, a kernel memory configured to provide the kernel coefficients to the plurality of nano cores, and a functional safety processor core configured to receive a result of a pattern recognition operation outputted from the plurality of nano cores to detect the presence of a recognition error, and perform a fault tolerance function on the detected recognition error.
