PROBLEM TO BE SOLVED: To increase the vector arithmetic processing speed with mask data following a single loop or a merged loop that is formed in a compiling mode. SOLUTION: A mask generation instruction vgsm(vector generate subarray mask) is outputted when a source program part corresponding to the vector arithmetic with mask data is compiled. The instruction vgsm is a machine instruction which can be directly executed by hardware. That is, the instruction vgsm sets a series part equivalent to the vector length (length of an accessed range) starting at a position that is shown by the value of a gr3 (general-purpose register) at a mask register mr among the series which repeated a basic pattern 1 consisting of the total number of value of gr2 (general-purpose register) after the false value (0) equivalent to the number of value of a gr1 (general-purpose register) continues and then the true value (1) continues. The pattern 1 can also use a series that consists of a prescribed number of truth value and a prescribed number of false value following the truth value.
