Abstract

A single instruction multiple data stream ("SIMD") processor includes multiple processing elements ("PEs"). Each PE includes a memory, a first multiplexer, an instruction register, a local instruction buffer for storing an instruction and a unit for modifying the instruction, in its entirety, to create a modified instruction. The modified instruction is stored in the local instruction buffer until it is executed. This structure modifies the instruction broadcast from the central controller of an SIMD computer in its entirety and creates modified instructions which can be unique to each PE.
