Abstract
PURPOSE: To shorten an access time to improve a processing speed by shortening signal line length between a processing unit and a white-system memory and limiting the read operation only to the white-system memory and performing information write for both system memories.
CONSTITUTION: In case that two processing units CC0 and CC1 execute the same program and perform a synchronous operation, they read out memory contents from white-system memories MM0 and MM1, which are connected with the shortest distance by signal lines 1 and 1', to execute the program. In case that information is written from one unit CC0 or CC1 to memories MM0 and MM1, the same instruction is executed synchronously by units CC0 and CC1 simultaneously, and the same information is written in both system memories MM0 and MM1.
