ABSTRACT:
Vector registers having logically equal address are arranged as two banks which can independently access ultra high speed RAM's. One bank holds all even-numbered elements of vector data and the other bank holds all odd-numbered elements of the vector data. A write address generator and a read address generator which are one half as fast as a clock rate of a machine cycle and which have a phase difference of one half period therebetween are provided so that the clock rate of the machine cycle may be set to one half of a total time of a write pitch and a read pitch of the vector registers.
