Abstract: A same instruction different operation (SIDO) processor is disclosed in which the instruction control word is supplied using data bus as one operand and the data to be operated is supplied through another operand. Also disclosed is a method for the provision of operation-code along with data/operands using a short instruction word. With all the execution units working in parallel on multiple data operands, a variety of operations can be performed in parallel. This allows short instruction format and flexibility to dynamically program the processor on the fly by changing data/operand words, and supports basic integer operations using very simple and efficient hardware execution units.

Abstract: A media signal processor (MSP) architecture is disclosed in this invention To address the shortcomings of conventional high performance processing units, the MSP architecture is designed using a new concept in parallel processing—“Same Instruction Different Operation” (SIDO) and “Same Instruction Multiple Data” (SIMD) architectures. The scalable nature of the architecture makes it possible to add multiple cores to match the processing needs of any type of data processing application. With multiple MSPs working in parallel, multiple data streams can be processed in either parallel or in a sequentially pipelined manner, using a software-based control mechanism.
