An identification of internal components of a Central Processing Unit (CPU).
Arithmetic and logic unit: An arithmetic and logic unit (ALU) performs arithmetic and logic functions that are created by the computer. The A and B registers hold the input data, and the accumulator receives the result of the operation. The command register contains the command that the ALU must execute.
Instruction pointer and register: The instruction pointer specifies the location in memory that contains the next instruction to be executed by the CPU. When the CPU finishes executing the current instruction, the next instruction is loaded into the instruction register from the location pointed to by the instruction pointer.
Cache: Cache is faster than system RAM and it's closer to the processor because it's on the processor chip. Cache provides data storage and instructions that prevent the CPU from waiting for data to be retrieved from RAM. When the processor needs data (and program instructions are also treated as data), the cache determines where the data has been and makes it available to the processor.
Memory Management Unit: The Memory Management Unit (MMU) manages the flow of data between the main memory (RAM) and the CPU. It also provides the memory protection and conversion between virtual memory addresses and physical addresses required in multitasking environments.
Processor Clock and Controller: All processor components must be synchronized to work properly with each other. The control block performs this function at a rate determined by the clock speed and is responsible for directing the operation of other blocks using synchronization signals extending throughout the CPU.
Processor Clock and Controller: All processor components must be synchronized to work properly with each other. The control block performs this function at a rate determined by the clock speed and is responsible for directing the operation of other blocks using synchronization signals extending throughout the CPU.
Random Access Memory (RAM): It is not actually part of the processor. Its function is to store programs and data so that they are ready for use when the processor needs them.
