Abstract
A vector processor for executing vector instructions comprises a plurality of vector registers and a plurality of pipeline arithmetic logic units. The vector registers are constructed with a circuit which operates in a speed equal to 2n times as fast as the processing speed of the pipeline arithmetic logic units. Either the read or the write operation from or to the vector registers are carried out in the time obtained by a processing cycle of each of the pipeline arithmetic logic units multiplied by n/2.
