It is important to note that DEBUG/RELEASE mode only affects the C kernel implementation, and thus the repeated runs for the assembly implementations can simply be looked at as more data to draw ...

This project serves as a comparative analysis of the execution times of C-based, non-SIMD x86-64-based programs, and SIMD x86 AVX2-based programs. To do so, the same kernel was programmed in C, ...

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 ...

Abstract: SIMD extensions have been a feature of choice for processor manufacturers for a couple of decades. Designed to exploit data parallelism in applications at the instruction level and provide ...

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 ...

Abstract: Modern multicore hardware employs a variety of parallel execution units, including multiple CPU cores for executing multiple threads simultaneously, vector units such as the Intel SIMD on ...

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 ...
