What is the recommended size of cache memory in a processor?
The maximum size of a cache memory is theoretically equal to the amount of primary memory(RAM).Like Cache only memory architecture where the whole memory space is filled up with the cache only.
Cache memory and register memory?
Register memory are smaller in size than cache memory and registers are faster than cache..Cache memory store the frequently used data from main memory..
Why is cache memory smaller than main memory?
because cache memory is costlier than main memory and physical size of cache memory also matters.ignoring the cost , if we use large cache memory, it will take larger physical space.so mother board won't be able to accomodate it
What is the size of L1 and L2 cache?
Usually the size of the L2 cache will be larger than the L1 cache so that if data hit in L 1 cache occurs, it can look for it in L 2 cache.. If data is not in both of the caches, then it goes to the main memory...
What is an example of L2 cache memory size?
Level 2 (L2) cache is built onto the processor. On Older slot-mounted processors, L2 cache was external to the processor die, and ran at slower speeds than the processor. on socketed processors, L2 cache is built onto the processor. If the processor does not find the desired memory locations in L1 cache, it checks L2 cache next. However Processors with larger L2 caches perform most tasks much more quickly than processors that have smaller L2 caches for two reasons. Cache memory is faster than main memory and the processor checks cache memory for needed information before checking main memory.
How do you calculate the cache size for a system?
To calculate the cache size for a system, you typically need to consider the cache line size, the number of cache sets, and the associativity of the cache. The formula for calculating cache size is: Cache Size (Cache Line Size) x (Number of Sets) x (Associativity). This formula helps determine the total amount of memory that can be stored in the cache for faster access by the system.

How can I use a cache calculator to optimize the performance of my system?
To optimize system performance using a cache calculator, input the cache size, block size, and associativity to determine the most efficient configuration for your system's cache memory. This can help reduce memory access times and improve overall system speed.
Diagram to show the address mapping of RAM and Cache?
consider a RAM of 64 words with a size of 16 bits.Assume that this memory have a cache memory of 8 Blocks with block size of 32 bits.Draw a diagram to show the address mapping of RAM and Cache, if 4-way set associative memory scheme is used.
What is the cache memory used for?
Cache is a high speed buffer memory for storing automatically small areas of frequently used memory, so that the machine does not have to wait for the full memory access time every time it needs to access the data in those areas.Most computers have separate but similar cache memories for data and instructions. This allows the same access time advantages for both, but as data and instructions are usually in different places in memory eliminates any conflicts in usage.Some computers have multiple levels of different speed cache with different sizes. These are typically referred to as L1 cache, L2 cache, L3 cache, etc. with L1 being the fastest, most expensive, smallest size cache closest to the processor; the others are successively closer to the main memory.
Which is more important cache size or processor speed?
Processing speed is far more important than cache size. Cache is a small amount of memory located in, or around the processor that is used to store small amounts of information that the processor can refer to as a quick reference. There are millions of bits flowing through cache memory every time the processor works. Any more, there is a standard amount of cache memory that is in every processor. Speed is a totally different thing and almost has nothing to do with cache size. Speed is definitely more important.
