Abstract
A method and device for varying the size of partitioned areas of a shared memory is disclosed. The present invention resets the size of partitioned areas by expanding the size of a shared area when data that is larger than the writable area of the shared area is to be written, after the storage area of a memory unit is partitioned to a plurality of partitioned areas by a main control unit. The memory unit is coupled with a main control unit and a supplementary control unit through independent ports. With the present invention, the data communication time between control units for processing data can be minimized, and the operation speed of each control unit can be optimized.
