What is hardware acceleration and why does it matter?

YouTube video decoding is one of the most common uses of hardware acceleration

“Hardware acceleration” is an possibility you might have noticed tucked away within the choices menu of more than a few packages throughout a lot of your gadgets, together with your Android smartphone. While no longer all the time an obtainable possibility in maximum smartphone apps, hardware acceleration is utilized by a variety of standard Android apps, together with YouTube ^(https://www.rootraw.com/youtube-not-working-811174/), Chrome ^(https://www.rootraw.com/best-android-browsers-320252/), Facebook ^(https://www.rootraw.com/facebook-apps-999160/), and extra.

Editor’s Pick

Use circumstances for hardware acceleration vary from extra environment friendly video and sound rendering, via smoothing out textual content, and dashing up 2D graphics and UI animations. In a nutshell, if in case you have the choice, it’s highest to make use of hardware acceleration, except it reasons some fault or worm.

If you’ve ever puzzled what hardware acceleration is and whether or not or no longer you must permit it, you’ve come to the appropriate position.

What is hardware acceleration?

The identify provides the sport away right here — hardware acceleration makes use of devoted hardware to boost up a role in order that it runs quicker and/or extra successfully than at the CPU on my own. Most repeatedly, this comes to offloading processing to the graphics processing unit (GPU), virtual sign processor (DSP), or every other hardware block that’s specialised on a selected process.

If this all sounds somewhat acquainted to heterogeneous computing ^(https://www.rootraw.com/qualcomm-kryo-and-heterogeneous-computing-explained-639243/), you’d be proper. However, repeatedly used kinds of acceleration are frequently uncovered in the course of the working machine to app builders, quite than depending on a devoted platform SDK to get admission to the more than a few computing elements. With acceleration disabled, CPUs are nonetheless ready to run the specified serve as in tool, albeit slower than on devoted hardware.

Hardware acceleration invokes a specialised processor to hurry up commonplace, advanced duties.

One of the most typical use circumstances for hardware acceleration is video encoding and interpreting. For instance, quite than interpreting a video circulation at the CPU, which isn’t very environment friendly, graphics playing cards or different hardware frequently comprises devoted video encode/decode blocks that may do the duty a lot more successfully. Likewise, decompressing an audio document can frequently be performed quicker on a DSP or sound card than at the CPU.

Another quite common use for hardware acceleration is 2D graphics acceleration. User interfaces, as an example, frequently function a number of graphics, textual content, and animations to render. This will also be performed at the CPU, however a GPU or show processor is so much quicker at this sort of operation. Tasks may come with making use of an antialiasing clear out to textual content so it seems smoother, or layering a semi-transparent overlay on most sensible of any other component like a video. Other complicated graphics examples come with accelerating physics and ray-traced lighting fixtures.

Why hardware acceleration issues

The CPU is the generic workhorse of any pc machine. It’s designed to take care of nearly any process that may be thrown at it, however this adaptability approach it’s frequently no longer the best strategy to accomplish particular duties, particularly those who require a number of repeated math purposes like video interpreting or graphics rendering.

Improving battery lifestyles, functionality, and responsiveness is the purpose of the sport.

Hardware acceleration offloads commonplace duties from the CPU to specialised hardware that may no longer simplest run the duty quicker but in addition a lot more successfully. This implies that gadgets run cooler and batteries remaining for lots longer. So you’ll have the ability to watch many extra top quality movies on a unmarried price when the usage of a devoted video decoder block as opposed to operating the set of rules at the CPU. Not forgetting that this additionally frees up your CPU to do different issues within the interim, making apps really feel extra responsive.

The tradeoff is that together with further processing hardware for particular options has a price, each on the subject of construction prices and additionally silicon space. Decisions must be made about which options are value supporting with hardware, reminiscent of very talked-about video formats, and which don’t relatively meet the required price/receive advantages ratio.


Hardware acceleration has turn into the most important device in pc methods starting from high-performance PCs to low-power smartphones. The use circumstances for devoted hardware are simplest rising with the creation of system studying packages. That stated, more often than not hardware acceleration is simply getting used to avoid wasting on battery lifestyles whilst streaming movies from YouTube.
