(2)MIMD:多指令流多数据流(Multiple Instruction Multiple Data),它使用多个控制器来异步地控制多个处理器,从而实现空间上的并行性。传统的顺序执行的计算机在同一时刻只能执行一条指令(即只有一个控制流)、处理一个数据(即只有一个数据流),因此被称为单指令流单数据流计算机。而对于大多数并行计算机而言,多个处理单...

MIMD Defined The MIMD architecture performs multiple actions simultaneously on numerous data pieces. One example is performing various mathematical calculations -- such as addition and multiplication -- simultaneously in order to solve a complex math problem with many separate components. MIMD computing ma...
在计算机体系中,数据并行有两种实现路径:MIMD(Multiple Instruction Multiple Data,多指令流多数据流)和SIMD(Single Instruction Multiple Data,单指令流多数据流)。其中MIMD的表现形式主要有多发射、多线程、多核心,在当代设计的以处理能力为目标驱动的处理器中,均能看到它们的身影。同时,随着多媒体、大数据、人工智能等...

多态并行处理器实现了单指令多数据(SIMD)和多指令多数据(MIMD)计算模式的混合,其结构简单,功耗低,同时在阵列机上分区并发实现该两种模式,并且能够在两种模式间实现一步转换[4-5]。其中SIMD控制器能够针对图形图像处理算法开发出更多的数据并行性[6],提高图形图像的处理性能。

MIMD:指令和数据都可以并行,不同的核心可以对不同的数据执行不同的指令流,可以认为是多个SISD的并行? SIMT:可以认为是SIMD的升级版,同一条指令可以被多个并发线程执行,并且不同线程执行的统一指令,其操作数也可以不同。 Fermi架构 有16个SM (Streaming Processor),即上图黑框 ...
The new architecture merges processor and memory with multiple PMEs (eight 16 bit processors with 32K and I/O) in DRAM and has no memory access delays and uses all the pins for networking. The chip can be a single node of a fine- grained parallel processor. Each chip will have eight ...
These observations are further exploited in the design of the single-chip SIMD processor array to be included in the MIMD-style overall system. The ... T Killeen,M Celenk 被引量: 0发表: 1993年 Post-Print The VEGA moderately parallel MIMD , moderately parallel SIMD , architecture for high ...
