Hardware acceleration is the use of computer hardware designed to perform specific functions more efficiently when compared to software running on a general-purpose central processing unit (CPU). Any transformation of data that can be calculated in software running on a generic CPU can also be calculated in custom-made hardware, or in some mix ...
DirectX Video Acceleration (DXVA) is a Microsoft API specification for the Microsoft Windows and Xbox 360 platforms that allows video decoding to be hardware-accelerated. The pipeline allows certain CPU -intensive operations such as iDCT , motion compensation and deinterlacing to be offloaded to the GPU .
AES-NI (or the Intel Advanced Encryption Standard New Instructions; AES-NI) was the first major implementation.AES-NI is an extension to the x86 instruction set architecture for microprocessors from Intel and AMD proposed by Intel in March 2008.
Compositing managers use hardware acceleration through this extension, if available. Ubuntu 8.04 Hardy Heron running Compiz's Shift Switcher in Flip mode. Under X11, the ability to do full 3D-accelerated compositing required fundamental changes to the window system protocol in order to use hardware acceleration.
Intel SHA Extensions are a set of extensions to the x86 instruction set architecture which support hardware acceleration of Secure Hash Algorithm (SHA) family. It was specified in 2013. [ 1 ] Instructions for SHA-512 was introduced in Arrow Lake and Lunar Lake in 2024.
Choice of GPU: All RemoteFX features can be used with either a software-emulated GPU, which is available by default in all virtual machines and session hosts, or they can benefit from hardware acceleration when a physical video card is placed in the server and the RemoteFX vGPU is enabled. [11] In addition, the following components were updated:

Codec acceleration describes computer hardware that offloads the computationally intensive compression or decompression. This allows, for instance, a mobile phone to decode what would generally be a very difficult, and expensive video to decode it with no stuttering, and using less battery life than un-accelerated decoding would have taken.
