Difference between scratchpad and cache
WebBoth the cache and Scratch-Pad SRAM allow fast access to their residing data, whereas an access to the off-chip memory (usually DRAM) requires relatively longer access times. … Scratchpad memory (SPM), also known as scratchpad, scratchpad RAM or local store in computer terminology, is an internal memory, usually high-speed, used for temporary storage of calculations, data, and other work in progress. In reference to a microprocessor (or CPU), scratchpad refers to a special high-speed memory used to hold small items of data for rapid retrieval. It is similar to the usage and size of a scratchpad in life: a pad of paper for preliminary …
