Difference between Cache Memory and Register
Parameters |
Cache Memory |
Register |
---|---|---|
1. Definition |
In a computer, the cache is the smallest and fastest part of the memory system. |
Registers make up a small portion of the computer CPU and are quick storage components. |
2. Data Stored |
A computer’s cache stores information and data that has been recently used. |
Registers store the data that the computer’s CPU is currently working on. |
3. Used by CPU |
To find previously stored data, the CPU uses the cache memory. |
The CPU uses registers to process all new data and information. |
4. Location |
The cache can be found either inside the CPU or on the main circuit board of the computer. |
Registers are a component located within the CPU itself. |
5 Data Processing |
It keeps information in a processed state, ready for use. |
It keeps information in an unprocessed state, waiting to be worked on. |
6. CPU Memory Access Speed |
Compared to registers, the CPU can access cache memory significantly faster. |
The CPU can perform many operations on data in registers within a single clock cycle when using registers. |
7. Examples |
Examples of cache include database query cache, web browser cache, and more. |
An example of a register is the loop register. |
What is Register Memory?
Register memory is a type of computer memory that consists of a small set of storage locations within the central processing unit (CPU) itself. These storage locations, known as registers, are used to store data temporarily during the execution of a program. More and bigger registers allow faster CPU operation. Different register types like accumulators, data registers, and address registers serve different purposes for the CPU.
