单指令 meaning in English
single instruction/multiple data (simd)
Examples
- Its 64 - bit capability and single instruction multiple data simd unit accelerate computationally intensive workloads such as multimedia and graphics
它64位的处理能力和单指令多数据（ simd ）单元可以加速计算密集型的应用，例如多媒体和图形。 - The main works were listed below : 1 . as the core of image tracker , the advanced dsp technology ( adsp - ts201 ) and the programmable logic device ( ep1s40f1020 chip ) were combined together to make certain that instruction was completed within single instruction period
主要体现在下面几点: 1 .图像跟踪器的硬件平台以先进的dsp技术( adsp - ts201 )和可编程逻辑器件( stratix系列的ep1s40f1020芯片)为核心,构成实时的图像跟踪处理器,使得指令可在单指令周期内完成运算。 - Although gpu has a very high computing speed , algorithms implemented in cpu cannot be put to execute in gpu directly because of the discrepancy in instruction execution manner of the two . gpu ' s architecture is a high parallel simd instruction set system . to reimplement algorithms insufficient to run on cpu with programmable graphics hardware , it has to reconsider the data structures and procedures to implement them to make full use of the
虽然gpu具有非常高的计算速度,但并不能将以前在cpu中实现的算法直接放到gpu中来执行,这是因为gpu的指令执行方式和cpu不一样, gpu的体系结构是一种高度并行的单指令多数据( simd )指令执行体系,所以要在可编程图形硬件上实现在cpu中效率不高的算法,就需要重新制定算法实现的数据结构和步骤,以充分利用gpu并行处理体系结构带来的性能优势。
