Intel is bringing its AVX-512 instruction set to desktop CPUs with its upcoming Cannon Lake CPUs, but AVX-512 is a good deal more complex than previous SIMD sets, and its capabilities are distributed ...

Is low-level programming a sin or a virtue? It depends. When programming for using vector processing on a modern processor, ideally I’d write some code in my favorite language and it would run as fast ...

I've two functions that I've tested for speed. Both are rather fast in practice, but one that does 1/4th the work is twice as slow. C-like: function compare16Byte(P1, P2 : Pointer; Length : integer) : ...

The PlayStation 3's Cell Broadband Engine was fairly unlike any other processor. It had capabilities that make emulating the system surprisingly demanding, even for modern hardware. As we've reported ...

Intel announced new extensions to AVX today -- the SIMD standard is headed up to 512 bits wide in future versions of Xeon Phi, with mainstream CPU integration likely in the 2015 timeframe. Share on ...

In 2013 Intel will release the AVX2 instructions, which introduce 256-bit Single-Instruction Multiple-Data (SIMD) integer arithmetic. This will enable desktop and server processors from this vendor to ...

Single-instruction, multiple-data (SIMD) instructions that can process multiple data with one instruction greatly contribute to the speedup of CPU operation. However, since SIMD instructions require a ...
