Abstract
A memory control unit for a computer has the function of extracting or synthesizing only a necessary portion from or to two-dimensional image scan data, in addition to a conventional main memory function. It comprises an address controller for calculating an address of data to be transferred based on source and destination start addresses A.sub.1 and A.sub.2 of the two-dimensional image scan data, a lateral length W.sub.1 and a longitudinal length of the necessary portion, and lengths I.sub.1 and I.sub.2 of unnecessary portion, and a controller for controlling memory read/write operation.
