Direct Memory Access

Question

Locality of Reference is use Cache Memory but not DMA. Why?

I mean atleast temporal locality should use DMA. as definition of temporal locaity is "Temporal locality refers to the reuse of specific data, and/or resources, within a relatively small time duration"

So, it can use direct memory . right?

@Shubham 

I just tried a divide and conquer strategy ;p

I  break the word locality of reference and tried to find the meaning

Here I thought locality means some part of area

and reference means it is refering those data

that is very informal thing I thought

U can chk here a question https://gateoverflow.in/2593/gate1995-1-6

hope got it

@srestha yes correctly said  locality of reference means that only..

DMA is use to transfer the data between I/O to Main memory.

Main memory do not flushes its data within certain interval so we need not to use temporal locality.
