The TI-99/4A has 256 bytes of scratchpad memory on the 16-bit bus containing the processor registers of the TMS9900 [2] Cyrix 6x86 is the only x86-compatible desktop processor to incorporate a dedicated scratchpad. SuperH, used in Sega's consoles, could lock cachelines to an address outside of main memory for use as a scratchpad.
Current embedded processors particularly in the area of multimedia applications and graphic controllers have on-chip scratch pad memories. In cache memory systems, the mapping of program elements is done during run time, whereas in scratchpad memory systems this is done either by the user or automatically by the compiler using a suitable algorithm.
This hint is used to discard cache lines, without committing their contents to main memory. Care is needed since incorrect results are possible. Unlike other cache hints, the semantics of the program are significantly modified. This is used in conjunction with allocate zero for managing temporary data. This saves unneeded main memory bandwidth ...
A scratchpad memory is working memory for a component of a computing system, and is not a cache or similar to a cache in its role. Shmuel (Seymour J.) Metz Username:Chatul 01:07, 25 February 2021 (UTC)
A CPU cache is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. [1] A cache is a smaller, faster memory, located closer to a processor core, which stores copies of the data from frequently used main memory locations.
CPU cache memory is divided into an instruction cache and a data cache. Harvard architecture is used as the CPU accesses the cache. In the case of a cache miss, however, the data is retrieved from the main memory, which is not formally divided into separate instruction and data sections, although it may well have separate memory controllers ...
Scratchpad may refer to: A pad of paper, such as a notebook , for preliminary notes, sketches, or writings Scratchpad memory , also known as scratchpad, scratchpad RAM or local store, is a high-speed internal memory used for temporary storage of calculations, data, and other work in progress
