The basic architecture of the Direct Rendering Infrastructure involves three main components: [8] the DRI client —for example, an X client performing "direct rendering"— needs a hardware-specific "driver" able to manage the current video card or graphics adapter in order to render on it.
The BYTE magazine, in December 1983, discussed Microsoft's plans for a system to output graphics to both printers and monitors with the same code in the forthcoming first release of Windows. [2] On Windows 3.1x and Windows 9x, GDI can use Bit blit features for 2D acceleration, if suitable graphics card driver is installed. [3]
Microsoft first introduced the EdgeHTML rendering engine as part of Internet Explorer 11 in the Windows Technical Preview build 9879 on November 12, 2014. [8] Microsoft planned to use EdgeHTML both in Internet Explorer and Project Spartan; in Internet Explorer it would exist alongside the Trident 7 engine from Internet Explorer 11, the latter being used for compatibility purposes.
A distinctive feature of the engine is that it JIT compiles scripts on a separate CPU core, parallel to the web browser. [1] [2] Though Microsoft has in the past pointed out that other elements, such as rendering and marshalling, are just as important for a browser's overall performance, [3] their improvements to the engine were in response to evolving competing browsers, compared to which IE8 ...
WDDM drivers allow video memory to be virtualized, [6] and video data to be paged out of video memory into system RAM. In case the video memory available turns out to be insufficient to store all the video data and textures, currently unused data is moved out to system RAM or to the disk. When the swapped out data is needed, it is fetched back.
The Direct Rendering Manager (DRM) is a subsystem of the Linux kernel responsible for interfacing with GPUs of modern video cards. DRM exposes an API that user-space programs can use to send commands and data to the GPU and perform operations such as configuring the mode setting of the display.
Software renderer running on a device without a GPU. Software rendering is the process of generating an image from a model by means of computer software. In the context of computer graphics rendering, software rendering refers to a rendering process that is not dependent upon graphics hardware ASICs, such as a graphics card.
While code integrity is usually achieved by unit testing the source code to reach high code coverage, it is definitely not the only way, or the best way, to achieve code integrity. In fact, code coverage, a popular metric to measure the thoroughness of unit tests, is known to have a limited correlation with the measure of real code integrity. [2]
