Vector processor with plural arithmetic units for processing a vector data string divided into plural register banks accessed by read pointers starting at different positions

摘要

It is an object to speed up a vector store instruction on a memory that is divided into banks as setting a plurality of elements as a unit while minimizing an increase in physical quantity. A vector processing apparatus has a plurality of register banks and processes a data string including a plurality of data elements retained in the plurality of register banks, wherein: the plurality of register banks each have a read pointer 113 that points to a read position for reading the data elements; and the start position of the read pointer 113 is changed from one register bank to another. For example, consecutive numbers assigned to the register banks may be used as the read start positions of the respective register banks.
