1 results about "SIMD" patented technology

Single instruction, multiple data (SIMD) is a class of parallel computers in Flynn's taxonomy. It describes computers with multiple processing elements that perform the same operation on multiple data points simultaneously. Such machines exploit data level parallelism, but not concurrency: there are simultaneous (parallel) computations, but only a single process (instruction) at a given moment. SIMD is particularly applicable to common tasks such as adjusting the contrast in a digital image or adjusting the volume of digital audio. Most modern CPU designs include SIMD instructions to improve the performance of multimedia use. SIMD is not to be confused with SIMT, which utilizes threads.

Computing group structure for superlong instruction word and instruction flow multidata stream fusion

InactiveCN101021778AAvoid wastingImprove execution efficiencyConcurrent instruction executionArchitecture with multiple processing unitsMicrocontrollerData stream
This invention discloses a VLIW with single-instruction multiple data streams converging computing cluster structure, which includes the data buffer and microcontroller connected with main controller, and their connective computing cluster. The main controller are responsible for the instruction and data mobile, instruction loads in the microcontroller, data loads in the data buffer and receives their output. The data buffer receives main controller data, supplies operation data for computing cluster and receives its result, and outputs to the main controller. Microcontroller receives the VLIW sequence form main controller, decodes and broadcast to each processing unit for parallel execution. The computing group includes a number of same processing units with a number of dealing components respectively and the same instruction sequence, and the data is from different modules of data buffer.
