WebThe buffer is a region in a memory that is accessible (i.e., read/write) by both the host processor and the PPU 200. For example, the I/O unit 205 may be configured to access the buffer in a system memory connected to the interconnect 202 via memory requests transmitted over the interconnect 202. WebThe cache memory basically acts as a buffer between the main memory and the CPU. Moreover, it synchronizes with the speed of the CPU. Besides, it stores the data and instructions which the CPU uses more frequently so that it does not have to access the main memory again and again. Therefore the average time to access the main memory …

WebSep 16, 2024 · Cache memory as mentioned in the introduction is a high-speed memory, which is smaller in size though faster than the main memory (RAM). The CPU can reach it more quickly than the primary memory. Therefore it is also used to synchronize with a high-speed CPU furthermore to improve its performance. WebFeb 13, 2024 · Caches act as a high-speed buffer between CPU and Main Memory. It improves performance by making the data needed in pipeline available within a few cycles, thereby preventing stalling in the pipeline.

WebThe speed of the CPU is generally faster than main memory's speed. This results in slow down in processing speed of the CPU as main memory is not able to provide data and instruction as per CPU's processing rate. So a technique was developed of using a small, high speed cache memory and place it in between CPU and main memory.
