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 ...

Many high-performance DSP and general-purpose processors are equipped with SIMD (single-instruction, multiple data) hardware and instructions. SIMD enables processors to execute a single instruction ...

Key to efficient hardware emulation is an efficient mapping to the underlying CPU’s opcodes. Here one is free to target opcodes that may or may not have been imagined for that particular use. For ...

This week Jonathan chats with Konstantinos Margaritis about SIMD programming. Why do these wide data instructions matter? What’s the state of Hyperscan, the project from Intel to power regex with SIMD ...
