Vector data buffer and method of reading data items from a banked

Abstract

A vector data processor includes a vector data buffer for receiving a plurality of arrayed data items requested from a storage including a plurality of storage banks (banks-0-3 in FIG. 2) for independent operations. The vector data buffer is constructed of a plurality of bank memories which conform to a corresponding periodic relationship between the arrayed data items and the storage banks. Date storing areas for storing the arrayed data items are preset on the successively different bank memories of the vector data buffer in the sequence in which the individual arrayed data items have been requested. The individual storage banks in the sequence in which the arrayed data items have been requested are respectively connected to the successively different bank memories, and the arrayed data items fetched from the individual storing banks are stored in the connected bank memories in succession.
