Abstract
The objective of the invention is to improve the processing efficiency of a system that repeatedly executes one instruction over multiple clock cycles. The SVP core of this SVP (Scan-line Video Processor) is made up of a three layer construction of the data input register (DIR) the SIMD type digital signal processing unit and the data output register (DOR) The SIMD type digital signal processing unit comprises a parallel arranged (connected) number of processing elements (PE to PEN−1) (for example, 864 units) equal to the number of pixels N on one horizontal scan line. The instruction generator (IG) because the SVP core operates as an SIMD parallel processor, internally houses a RAM or ROM program memory that holds the desired program. The program stored in program memory contains not only the instructions (SIMD instruction) for the processing elements (PE to PEN−1) of the processing unit but also such instructions (IG instruction) as jump, subroutine call, hardware interrupt, and the like. In this SVP when an IG instruction is read from the program memory while the repetitive processing of an SIMD instruction is being conducted in the SVP core the pertinent IG instruction is executed in parallel with the repetitive processing of the pertinent SIMD instruction.
