Central processing unit
→
Digital logic circuits
depends on
A CPU consists of registers, an arithmetic logic unit, control logic, and interconnects, all implemented using digital logic.
Central processing unit
→
Semiconductor memory
depends on
The CPU needs main memory to store instructions and data; semiconductor memory enables memory hardware to shrink and memory access to speed up alongside the processor.
Large-scale integration
→
Central processing unit
enables
Once a single chip could accommodate more logic gates and registers, the main functions of a central processing unit could be condensed from circuitry spread across multiple boards onto fewer chips.
Microprocessor
→
Central processing unit
evolved from
A microprocessor integrates the main functions of a CPU onto a single chip that can be packaged, continuing the process of consolidation from board-level logic to large-scale integration.
Microprogramming
→
Central processing unit
part of
Microprogramming encodes the control sequences of complex instructions as microinstructions in control memory, providing an implementation method for some CPU control units.
