What is Intel® SSE4?
Intel SSE4 is a set of new instructions designed to improve the performance and energy efficiency of a broad range of applications. Intel SSE4 builds upon the Intel® 64 Instruction Set Architecture (ISA), the most popular and broadly used computer architecture for developing 32-bit and 64-bit applications. Intel SSE4 is the result of continued work with the ISV community to deliver instruction set extensions that allow developers to easily enhance their products while maintaining the necessary application-level compatibility across processor generations. Intel SSE4 consists of 54 instructions divided into two major categories: Vectorizing Compiler and Media Accelerators, and Efficient Accelerated String and Text Processing. Vectorizing Compiler and Media Accelerators provide high performance compiler primitives, such as packed (using multiple operands at the same time) integer and floating point operations, that allow for performance optimized code generation. It also includes highly o
