ABSTRACT:
A vector operation instruction issue control method includes a meter for measuring an elapse of a time period corresponding to a sum of the number of vector elements of a vector operation instruction and a difference between the number of pipeline stages of two arithmetic functions. When a vector operation instruction using an arithmetic function having a larger number of pipeline stages is issued to a vector arithmetic unit, the meter is activated to measure a time period corresponding to a sum of the number of vector elements of the vector operation instruction and the stage number difference. When a vector operation instruction using an arithmetic function having a smaller number of pipeline stages is issued subsequently to the vector operation instruction using the arithmetic function having the larger number of pipeline steps, the vector operation instruction using the arithmetic function having the smaller number of pipeline stages is issued in accordance with an end timing of the measurement of the meter.
