Dual-ported video RAM (VRAM) is a dual-ported variant of dynamic RAM (DRAM), which was once commonly used to store the framebuffer in graphics adapters. Dual-ported RAM allows the CPU to read and write data to memory as if it were a conventional DRAM chip, while adding a second port that reads out data.
Video memory was shared with the first 128 KiB of RAM. The exact size of the video memory could be reconfigured by software to meet the needs of the current program. An early hybrid system was the Commodore Amiga which could run as a shared memory system, but would load executable code preferentially into non-shared "fast RAM" if it was available.
Many modern GPUs rely on VRAM. In contrast, a GPU that does not use VRAM, and relies instead on system RAM, is said to have a unified memory architecture, or shared graphics memory. System RAM and VRAM have been segregated due to the bandwidth requirements of GPUs, [2] [3] and to achieve lower latency, since VRAM is physically closer to the GPU ...
HSA defines a special case of memory sharing, where the MMU of the CPU and the IOMMU of the GPU have an identical pageable virtual address space.. In computer hardware, shared memory refers to a (typically large) block of random access memory (RAM) that can be accessed by several different central processing units (CPUs) in a multiprocessor computer system.
The upgraded ViRGE/DX and ViRGE/GX models did improve 3D rendering performance, [2] but by the time of their introduction they were still unable to distinguish the ViRGE family in an already crowded 3D market. Outside of 3D rendering, ViRGE was a solid performer in familiar tasks as DOS VGA and Microsoft Windows.
Today, he is a local staple. He helped start Cops and Barbers, an initiative that brings law enforcement and community members together. The local NAACP in November awarded McFadden for his work ...
Windows automatically sets the size of the page file to start at 1.5× the size of physical memory, and expand up to 3× physical memory if necessary. If a user runs memory-intensive applications on a system with low physical memory, it is preferable to manually set these sizes to a value higher than default.
