SIMD Processor Performance Trends SIMD and MIMD SIMD
Modern SIMD Processors • Most modern CPUs have SIMD architectures o Intel SSE and MMX, ARM NEON, MIPS MDMX • These architectures include instruction set extensions which allow both sequential and parallel instructions to be executed • Some architectures include separate SIMD coprocessors for handling these instructions • ARM NEON o Included in Cortex-A8 and Cortex-A9 processors • Intel SSE o Introduced in 1999 in the Pentium III processor o SSE4 currently used in Core series
