4(30%). Convolution is the treatment of a matrix by another one which is called kernel. The convolution of a matrix by a given kemel is obtained by putting the kemel in front of every area of the matrix, like a sliding window, to do the element-wise product of the numbers in the kernel by the ones in the matrix it overlaps and summing all of those, like in the example below. This process is repeated by moring the kernel on every possible area of the matrix (stride=1), i.e., by moring one element in row or column. Develop an algorithm to do convolution on a nn matrix by a 33 kernel assuming CREW PRAM. What is the complexity of your algorithm? What is the complexity of your algorithm, assuming CRCW PRAM
