Abstract

PURPOSE: To make it possible to process data bit by bit by enable a CPU to attain access to an input or output register as well as an internal register.
CONSTITUTION: To perform the bit process of internal data (the content of accumulator 7), the internal data are outputted to internal bus 13 by accumulator selective signal (f) with read-write signal (e) in a write mode and at the same time, the content of bus 13 is set to temporary register 15 by control signal (b). In this way, the bit-unit process of the data of accumulator 7 can be performed through the same operations as the process of data of output register 11 and input register 10, only causing register selective signals to differ [selective signals of registers 10 and 11 are (j) and (i)]. Therefore, registers 10 and 11 can be used for the operand of logical operation as well as accumulator 7, etc., and bit processing can also be attained by using logical operation part AUU6.
