SIMD & SSE Instruction Set

In this article, we will discuss scalar computing (and some of its drawbacks), the need for vector/parallel computing, the fundamental concepts behind single instruction, multiple data (or SIMD) architecture, as well as one of its implementations in modern CPUs, namely: Intel's Streaming SIMD Extensions, or SSE for short.

Scalar Computing (SISD Architecture)

Before parallelization was widely implemented in computers systems around the world, scalar processors were used to solve computational pro...
