Central Processor Unit (CPU)
3.2 Introduction
3.3 CPU Control Unit
3.4 Arithmetic/Logic Unit
Technical Data
The central processor unit (CPU) consists of a CPU control unit, an
arithmetic/logic unit (ALU), and five CPU registers. The CPU control unit
fetches and decodes instructions. The ALU executes the instructions.
The CPU registers contain data, addresses, and status bits that reflect
the results of CPU operations. See
Features include:
The CPU control unit fetches and decodes instructions during program
operation. The control unit selects the memory locations to read and
write and coordinates the timing of all CPU operations.
The arithmetic/logic unit (ALU) performs the arithmetic, logic, and
manipulation operations decoded from the instruction set by the CPU
control unit. The ALU produces the results called for by the program and
sets or clears status and control bits in the condition code register
(CCR).
