Abstract
PURPOSE: To register insignificant codes in an address conversion buffer at a high speed by giving reference address of address conversion buffer from an address counter circuit as well.
CONSTITUTION: Reference addresses of address conversion buffer 10 can be given from not only outputs from logical address register 6 but also those of address counter circuit 31, and they are changed over under conditions where insignificant codes are registered in buffer 10. Further, counter 31, composed of a counter, for example, covers all addresses of buffer 10. As a result, the updata of the reference address of an insignificant code in buffer 10 is made independent from machine cycles of arithmetic control part 30 during insignificant code registration and counter circuit 31 can update the reference address. Therefore, insignificant codes can be registered at a high speed.
