Give two reasons why caches are useful?
It minimizes the miss match between the main memory and the processor Actually, there is one reason for a cache to exist: speed. A cache exists to speed up the time that the processor takes to obtain a bit of data. Typically, main memory is many times slower than the processor - in modern computers, it can be 1000 times slower. So, caches are made up of memory more expensive and faster than main memory, to store parts of main memory in, in the hopes that the data the processor wants will be available in the cache.
What is the function of cache memory?
Cache memory is used to hold a copy of the data from the most frequently accessed memory locations to minimise calculation time. For example, a CPU's cache will hold this data so that it doesn't have to call data from the RAM for every calculation it makes, and merely draws from its local cache.
Why not make cache larger?
A cache is intended to speed things up. The larger the cache, the slower it performs. If it becomes slower to access the cache than the memory itself, it defeats the purpose of having a cache.
What characteristics of the motherboard architecture determine the amount of memory that a CPU can address?
RAM and the memory cache
When data and instructions are not being used where are they kept?
Originally they're kept on the hard drive in the form of a program. Once run, the instructions and data are loaded into main memory until the processor is ready for them. They are then read into the various levels of CPU cache when awaiting execution.
What is the name of the memory cache that is shared by cores in a multicore processor?
L3 Cache
What is the name of the memory cache that is shared by cores in a multie-core processor?
L3 cache
What is a cache outside the processor called?
L2 cache. Today's processors all have some memory on the processor chip (called a die). Memory on the processor die is called Level 1 cache (L1 cache). Memory in the processor package, but not on the processor die, is called Level 2 cache (L2 cache). Some processors use a third cache farther from the processor core, but still in the processor package, which is called Level 3 cache (L3 cache).
What are the type of cache memory?
There are different type of cache memory: processor cache memory, cache memory ram,1 cache memory l2, cache memory, CPU cache memory, disk cache memory, hard disk cache, cache memory motherboard.
What memory serves as a staging area from the processor?
Cache memory
What are the two types of cache memory?
There are different type of cache memory: processor cache memory, cache memory ram,1 cache memory l2, cache memory, CPU cache memory, disk cache memory, hard disk cache, cache memory motherboard.
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.
What is the name of the memory that sits between the processor and the primary memory?
Cache
What is on chip memory?
It is integrated with Processor. Also called Cache Memory.
What is the memory of the cache that is closest to the processor die but is not housed on the die?
Level 2 cache (L2 cache)
