What is the task of cache memory of processors?

Question

for example 2 proccessors each one 3.2 GHz but one of them 512MB cache and another 256 MB of cache memory.
I know these numbers on a RAM but no Idea what about a proccessor memory, what is it for?
please.
thanks.

Answer 1

It is faster to access memory right on the CPU than having to retrieveit over the bus from the main RAM.

Answer 2

A center is nearly a human strategies, it does each and all the computations (I won't clarify how, this is extremely perplexing in case you don't understand electric powered logic). New processors have distinctive cores, the extra the extra effectual as extra calculations could nicely be finished concurrently part with the aid of part. Having an extra center is like having yet another processor. Intel have a characteristic called hyper-treadding the place it creates yet another logical center for each actual center so with an i7 severe version you are able to have 12 cores (6 actual, 6 logical) A cache is like RAM purely it has very extreme records pass expenses whilst in comparison with RAM. this is used for storing records oftentimes getting used. with the aid of fact it has extreme records pass expenses and does not ought to trip virtually as a the right thank you to get to the CPU to be calculated the records is despatched calculated and won plenty quicker than RAM.

Answer 3

Quite simple
1,. Go with the processor having 512 MB of cache (pronounce it as cash).
2. Cache mem is the mem between processor and RAM
3. Most of the time it hold the record (index ) of location of various instructions fetched from RAM to CPU.
4. So in case repetetion of instructions CPU need not to fetch it from RAM (data /instruction) and can pickup directly from the cache or may get the index location of same in the RAM or other storage device.
5. commonly u may have data or instruction cache or may have combination of both

Answer 4

The processor uses this cache memory for it to become faster. When it runs, it puts some amount of data to the cache memory so that when it needs those data again, its easier to access and it becomes faster.
