Which of the following gives the correspondence between the main memory blocks and those in the cache?
mapping function
The correspondence between the main memory blocks and those in the cache is specified by a mapping function.
What is the use of cache memory and main memory in program execution?
Cache memory is used to reduce the average time to access data from the Main memory. The cache is a smaller and faster memory which stores copies of the data from frequently used main memory locations. There are various different independent caches in a CPU, which store instructions and data.
How does cache memory speed up the CPU execution of instructions?
Cache memory holds frequently used instructions/data which the processor may require next and it is faster access memory than RAM, since it is on the same chip as the processor. This reduces the need for frequent slower memory retrievals from main memory, which may otherwise keep the CPU waiting.
What is the function of cache memory in a PC?
Cache memory temporarily stores information, data and programs that are commonly used by the CPU. When data is required, the CPU will automatically turn to cache memory in search of faster data access.
Which memory is assembled between memory and CPU?
Cache Memory
Explanation: It is called the Cache Memory. The cache memory is the high speed memory between the main memory and the CPU.
Which memory acts as a buffer between the CPU and the main memory?
Cache memory
Cache memory is an extremely fast memory type that acts as a buffer between RAM and the CPU. It holds frequently requested data and instructions so that they are immediately available to the CPU when needed. Cache memory is used to reduce the average time to access data from the Main memory.
How does the cache memory increase the speed of computer?
Cache memory allows for faster access to data for two reasons:
- cache uses Static RAM whereas Main Memory (RAM) uses dynamic RAM.
- cache memory stores instructions the processor may require next, which can then be retrieved faster than if they were held in RAM.
