Abstract
In a vector processor having vector registers, a vector buffer storage for temporarily storing vector data is arranged closer to the vector registers than to a main storage, and a vector buffer storage control including an identification storage for storing identification information of the vector data stored at storage locations of the buffer storage and a check circuit for checking if the vector data identification information is in the identificatgion storage is provided. The vector buffer storage control checks if the identification information of the vector data designated by a vector data fetch instruction for the main storage is in the indentification storage, and if it is in the identification storage, it fetches the vector data from the buffer storage and transfers it to the vector register, and if it is not in the identification storage, it instructs to fetch the vector data from the main storage, transfers the vector data fetched from the main storage to the vector register and stores it into the buffer storage.
