这本书则全面而详细的介绍了SIMD的设计理念和微架构实现方法,首先与其他并行技术包括超标量、多线程和多核技术进行了对比,之后分别介绍了SIMD三个最重要的方面:1.计算和控制流;2.内存操作;3.水平操作,是SIMD方面为数不多的好书。 具体是Synthesis Lectures on Computer Architecture系列中《Single-Inst
《Performance Impact of Unaligned Memory Operations in SIMD Extensions for Video Codec Applications》这篇文章,提出尝试访问未对齐的内存位置时,需要执行重新对齐的过程,这包括读取对齐的内存字、移除不必要的字节、读取相邻的对齐字并丢弃不必要的字节,最后合并提取的部分。这种重新对齐的过程可能会导致性能下降,有时...
This paper describes changes made to a previous implementation of an N -body tree code developed for a fine-grained, SIMD computer architecture. These changes include (1) switching from a balanced binary tree to a balanced oct tree, (2) addition of quadrupole corrections, and (3) having the...

In this paper we modify the architecture of the conventional microcontroller (C-51) using VHDL, also we develop some innovated special programmed instructions which utilize parallelism (via multiple processing units). Thus we present a modified superscalar processor using single instruction multiple data...
fundamental pillars of parallel computing. These architectures are the cornerstone upon which several parallel programming models are built. The evolution of these models closely mirrors advancements in computer architecture. Hence, understanding architectural intricacies becomes imperative for maximiz...
degree in Computer Architecture from the University of Granada in 2007. He is Computer Engineer in the Instituto de Astrofísica de Andalucía (IAA-CSIC) from 2008. He participated in the development of the flight, calibration, and control software for the IMaX instrument aboard Sunrise Balloon-...
The present invention relates in general to a single instruction, multiple data-reduced instruction set computer (SIMD-RISC) architecture. More particularly, the present invention relates to a microprocessor that includes a register file that is shared between a plurality of functional units, wherein ...
