Abstract

PURPOSE: To make it possible to elevate the function of LSI by a simple constitution, by forming an output terminal in one of two registers which operate separately, writing in before-hand the instruction for coupling these registers, and outputting serial signals as occasion demands.
CONSTITUTION: The accumulators ACC1 and ACC2 which operate separately are provided in the same LSI, one accumulator ACC2 is connected to the output terminal 9 of LSI, and the accumulators ACC1 and ACC2 are connected in series. Moreover, not only RAM is connected to the accumulator ACC1 but also the input terminals 1W4 which input the instruction for coupling the accumulators ACC1 and ACC2 are connected. And the input output terminals 5W8 are connected to the accumulator ACC2, the operation and the operation result are coupled in accordance with the instruction of the input terminals 1W4 by the FF circuit C and the operation part ALU, and in case of serial coupling, output signals are output serially from the output terminal 9, and simultaneously desired bit signals are output to the output terminals 10W13 and 14W17 through the output registers P3 and P4.
