The XAA/EXA/UXA/SNA APIs are for the 2D graphics drivers inside the X server.Note, that modern software uses direct rendering. Glamor obsoletes DDX, here with XWayland.. In computing, UMA Acceleration Architecture (UXA) is the reimplementation of the EXA graphics acceleration architecture of the X.Org Server developed by Intel.
Also known as: Integrated graphics, shared graphics solutions, integrated graphics processors (IGP) or unified memory architecture (UMA). This kind of graphics processors usually have much fewer processing units and share the same memory with the CPU. Intel Core i5 processor with integrated HD Graphics 2000
The memory in these machines is simply one fast pool (2.1 GB per second in 1996) shared between system and graphics. Sharing is performed on demand, including pointer redirection communication between main system and graphics subsystem. This is called Unified Memory Architecture (UMA).
Uniform memory access (UMA) is a shared memory architecture used in parallel computers.All the processors in the UMA model share the physical memory uniformly. In an UMA architecture, access time to a memory location is independent of which processor makes the request or which memory chip contains the transferred data.

The Unified Memory Architecture means that the O2 uses main memory for graphics textures, making texturing polygons and other graphics elements trivial. Instead of transferring textures over a bus to the graphics subsystem, the O2 passes a pointer to the texture in main memory which is then accessed by the graphics hardware.
Graphics represented as a rectangular grid of pixels. Rasterization Converting vector graphics to raster graphics. This terms also denotes a common method of rendering 3D models in real time. Ray casting Rendering by casting non-recursive rays from the camera into the scene. 2D ray casting is a 2.5D rendering method. Ray marching
The graphics address remapping table (GART), [1] also known as the graphics aperture remapping table, [2] or graphics translation table (GTT), [3] is an I/O memory management unit (IOMMU) used by Accelerated Graphics Port (AGP) and PCI Express (PCIe) graphics cards.
