PURPOSE:To execute logical operation, four arithmetical operations, comparing operation, etc. in each vector element and to speed up the vector processing by setting an instruction code for specifying the kind of operation in each vector element and referring the instruction code. CONSTITUTION:An instruction code for specifying the kind of the operation is added to each element of a vector B. Addition '+' is used for respective instruction codes of elements B(1)-B(N-20) of the vector B and a subtraction '-'is used for respective instruction codes of elements B(N-19)-B(N). When data vectors of the vector B and the vector C are operated in each element, the arithmetic circuit adds the elements B(1)-B(N-20) of the vector B to the elements C(1)-C(N-20) of the vector C while referring to the instruction codes added to respective elements of the vector B and subtracts the elements B(N-19)-B(N) of the vector B from the elements C(N-19)-C(N) of the vector C also while referring to the instruction codes. The calculated results of the arithmetic circuit are stored as a vector A (result vector).
