Definition of Simd

What does Simd mean?


  1. [computing]: Single Instruction Multiple Data


  1. SIMD: Single instruction, multiple data, 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. Thus, such machines exploit data level parallelism, but not concurrency: there are simultaneous computations, but only a single process at a given moment. SIMD is particularly applicable to common tasks like adjusting the contrast in a digital image or adjusting the volume of digital audio. Most modern CPU designs include SIMD instructions in order to improve the performance of multimedia use.
    • also known as 单指令流多数据流
  2. The simd, is an Ossetian folk group dance. Time signature 4/4, 2/4. The beauty of Simd is in the strict graphic outline of the dance, the contrast between black and white costumes, the softness of movements, the strictness of line formations, and the harmony created by all of the above. The Simds name names the State song and dance ensemble of South Ossetia “Simd” named after B. A. Galayev.
  3. SIMD is a cryptographic hash function based on the Merkle–Damgård construction submitted to the NIST hash function competition by Gaëtan Leurent. It is one of fourteen entries to be accepted into round two of the competition, but was not shortlisted for the third and final round.
