The control unit determines the particular instruction to be executed by reading the program counter (PC) (Englander, I. 2014). Primary memory holds program instructions and data and interacts directly with the CPU during program execution. The control unit also reads and interprets instructions from memory and transforms them into a series of signals to activate other parts of the computer. The control unit …show more content…
Cache memory is organized into blocks. Each block provides a small amount of storage, perhaps between 8 and 64 bytes, also known as a cache line. The block will be used to hold an exact reproduction of a corresponding amount of storage from somewhere in main memory (Englander, I. 2014). Another important factor is a processor's L2 cache, which stores memory data and speeds up operation by making recently accessed data immediately available to the processor. A register is a single, permanent storage location within the CPU used for a particular, defined purpose registers are used in several way in a computer it depends on the register it my hold data to be processed, an execution order for instruction or even memory or I/O address to be accessed registers can even process special binary codes that are used for special purposes.
