Unified Memory Access is not a valid term, but is often used mistakenly when referring to: Uniform Memory Access , a computer memory architecture used in parallel computers Unified Memory Architecture , a technology that allows a graphics processing unit to share system memory
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.
On systems with "Unified Memory Architecture" (UMA), including modern AMD processors with integrated graphics, [89] modern Intel processors with integrated graphics, [90] Apple processors, the PS5 and Xbox Series (among others), the CPU cores and the GPU block share the same pool of RAM and memory address space.
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).
Non-uniform memory access (NUMA) is a computer memory design used in multiprocessing, where the memory access time depends on the memory location relative to the processor. Under NUMA, a processor can access its own local memory faster than non-local memory (memory local to another processor or memory shared between processors). [ 1 ]
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
Unified memory A memory architecture where the CPU and GPU share the same address space, and often the same physical memory. It is common in Intel [34] [35] and AMD [36] [37] processors with integrated graphics, SoCs and video game consoles. Supported on some discrete GPUs with the use of an MMU. UV coordinates
