Configurable simd processor instruction specifying index to lut storing information for different operation and memory location for each processing unit

Abstract

Methods and apparatuses for processing a Configurable Single-Instruction-Multiple-Data (CSIMD) instruction are disclosed. In the method, a lookup table (LUT) storing information is provided to support random access of memory locations associated with a plurality of processing elements (PEs) and to perform instruction variances by the PEs. A CSIMD instruction is received, comprising a command and an index to the lookup table (LUT), to be executed by the PEs. The command of the received CSIMD instruction is executed in parallel differently by the PEs using the LUT index to randomly access the memory locations.
