| Components of CPU:
- The arithmetic logic unit (ALU), which performs arithmetic
and logical
operations.
- The control unit (CU), which extracts instructions from memory
and decodes and execute them, calling on the ALU when necessary.
CPU was housed inside a silicon chip called microprocessor. Microprocessor
has three basic characteristics which are:
- Instruction set - The set of instructions
that the microprocessor can execute.
- Bandwidth - The number of bits processed in
a single instruction.
- Clock speed - Given in megahertz (MHz or GHz),
the clock speed determines
how many instructions per second the processor can execute.
