When the processor needs to read from or write to a location in main memory, it
first checks whether a copy of that data is in the cache.
The first part gives an overview of cache, while the second part ... Cache memory
helps by decreasing the time it takes to move information to and from the ...
Cache memory, also called CPU memory, is random access memory (RAM) that
a computer microprocessor can access more quickly than it can access regular ...
called a cache between the main memory and the processor. The idea of ... first
presented to the cache memory, and if the cache cannot respond, the request is ...
the lower end of any common hierarchical memory design, this paper focuses on
optimization techniques for enhancing cache performance. The levels of the ...
