Abstract

PURPOSE:To make flexibly correspond to variations in the capacity of rapid memory, by transferring and planting micro-programs, which have been designated to plant in accordance with previously fixed rules to and in either the rapid memory or main memory after one of them is decided. CONSTITUTION:A data processing device is provided with a main memory, a rapid memory 2 which can read and write, and a reading-only memory (ROM)3. Micro-programs are read out by a micro instruction register 5 through addresses of each memory designated by a micro instruction address register 4, and the read out micro instruction is decoded by an execution control section 7 containing a micro instruction command decoder 6, and then, the execution is controlled. Moreover, contents of a rapid memory capacity register 13 are read out by an accumulator 11 in accordance with the micro instruction, and differences between the content of the register 13 and contents of a file 9 are obtained. An indicator 14 makes designations based on the difference, and memories are decided based on the result.
