Abstract

PURPOSE:To reduce the number of data processing circuits and to increase the processing speed, by using the same data processing with shifted timing to similar data processings, in duplicated data processors. CONSTITUTION:In the normal operation in which the operand is not in variable length, the address adders 7, 9 make the same operation at the same time, and the result is compared at a comparison circuit 11. In case the operand is in variable length, the 1st data processing S is made at the address adder 7 in the timing T1, and the 2nd data processing S+L is made at the address adder 9, the result of processing is stored to the register 8 at the address adder 7 and the result of processing at the address adder 9 is stored in the register 10. The data processing S+L is made at the address adder 7 in the next timing T2, and the data processing S is made for the result and the content of the register 10 at the address adder 9, and the result and the content of the register 8 are respectvely compared.
