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 ...

Both the Intel Xeon processor and the Intel Xeon Phi coprocessor continue to increase in performance as each generation is developed. To gain maximum performance from these architectures, it is ...

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 ...

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 ...

In this paper, we propose and explain two efficient optimization approaches on H264 decoder. 1. First method exploits efficient utilization of SIMD for deblocking filter. 2. The second method uses ...

As mentioned, SIMD processors have limited efficiency for the final image-processing steps that are either mainly serialized or require floating-point arithmetic. Additionally, when compared with ...
