ABSTRACT:
An execute module in a data processing system is provided with a randomly accessible scratchpad memory which is logically divided into two switchable pages. During operation one page can be written with new instruction data from a fetch module while a previously written page is concurrently being read by the execute module for execution of a designated data processing operation. When the execute module completes execution and requires a new block of data, the two pages are logically switched by toggling an address bit.
