Slab allocation is a memory management mechanism intended for the efficient memory allocation of objects. In comparison with earlier mechanisms, it reduces fragmentation caused by allocations and deallocations. This technique is used for retaining allocated memory containing a data object of a certain type for reuse upon subsequent allocations ...
Most standard techniques treat color quantization as a problem of clustering points in three-dimensional space, where the points represent colors found in the original image and the three axes represent the three color channels. Almost any three-dimensional clustering algorithm can be applied to color quantization, and vice versa. After the ...
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.
Texture memory is a type of digital storage that makes texture data readily available to video rendering processors (also known as GPUs), typically 3D graphics hardware. It was sometimes implemented as specialized RAM ( TRAM ) that is designed for rapid reading and writing, enabling the graphics hardware increased performance in rendering 3D ...
Illustration of cache coloring. Left is virtual memory spaces, center is the physical memory space, and right is the CPU cache.. A physically indexed CPU cache is designed such that addresses in adjacent physical memory blocks take different positions ("cache lines") in the cache, but this is not the case when it comes to virtual memory; when virtually adjacent but not physically adjacent ...
Although President-elect Donald Trump's children don't currently have White House roles in his second term, he's recently announced picks from his extended family by marriage to manage foreign ...
Many image file formats use data compression to reduce file size and save storage space. Digital compression of images may take place in the camera, or can be done on the computer with the image editor. When images are stored in JPEG format, compression has already taken place.
The management of scratch disk space is typically dynamic, occurring when needed. Its advantage is that it is faster than e.g. network filesystems. Scratch space is commonly used in scientific computing workstations, and in graphic design programs such as Adobe Photoshop. It is used when programs need to use more data than can be stored in ...
