Abstract

In a data processing system including a relatively large, page-formatted memory, memory control functions are distributed over a plurality of microprocessors connected in an array with each microprocessor controlling a respective area of the large memory. Upon overflow of its assigned memory area, a microprocessor may "borrow" free memory space assigned to one of its neighbors in the microprocessor array. Memory control functions with respect to different areas in the memory can effectively be performed in parallel, thus improving the operating efficiency.
