the type of SIMD instruction set architecture that is most common in contemporary consumer grade CPU:s. More specifically, I refer to non-predicated packed SIMD ISA:s where the details of packed SIMD processing is exposed to the software environment.
VMX and VelocityEngine)MIPS: MDMX, MIPS-3D, MSA, DSPSPARC: VISAlpha: MVI1 AVX and later x86 SIMD ISA:s (especially AVX-512) incorporate features from vector processing, making them packed SIMD / vector processing hybrids (thus some of the aspects discussed in this article do not fully apply).
a SIMD register contains four 32-bit elements), 4*24=96 elements can be processed in the main SIMD loop, and 99-96=3 elements need to be processed after t…
