FFmpeg Achieves 94x Speed Increase with AVX-512 Optimization

Originally Published 1 year ago — by Slashdot

FFmpeg developers have implemented a handwritten AVX-512 assembly code path, achieving performance boosts of up to 94 times in video processing tasks. This optimization leverages the AVX-512 instruction set to process large data chunks in parallel, significantly outperforming standard implementations and other SIMD instruction sets like AVX2 and SSSE3. The results underscore the potential of hand-optimized assembly code for enhancing compute-heavy tasks in multimedia processing.

DR-DOS Power Management Source Code Rediscovered in Patent.

Originally Published 2 years ago — by Hackaday

A missing DR-DOS power management source code has been found in a patent. DR-DOS 6.0 has a built-in feature for putting the CPU in power-saving mode when idle, but it required a customized IDLE driver for each hardware platform to enable power management. No manufacturer ever bothered to develop one, leaving users with no option but to write a driver themselves. A U.S. patent includes dozens of pages of well-documented but poorly-scanned x86 assembly code, including source code for a basic IDLE86.SYS driver, which can be used to create a working IDLE driver.
