ABSTRACT:
A vector processing system having a main storage, a vector processor, a scalar processor, and an address translation mechanism in each processor in which data is stored in the main processor. The vector processing system includes a common memory in which processing results of vector data can be directly stored from resources such as arithmetic circuits and an operand fetch logic in the vector processor without using the address translation mechanism and from which data can be directly read out by the resources in the scalar processor without using the address translation mechanism, a common memory access control circuit for controlling the conflict among access requests issued from a plurality of resources in the processors and for controlling the access right through an assignment of a block number in a unit of a logical partition of the common memory, and a circuit for controlling, depending on set information held in the control circuit, a decode operation of an instruction specifying operations of the scalar and vector processors.
