Study Notes
Control Unit
- The control unit is the component of the CPU that directs the operation of the processor.
- It uses control signals to direct the operation of other units in the CPU.
- In modern computer designs, the control unit is typically located in the microprocessor.
Computer Architecture
- The von Neumann computer architecture included the control unit as a part of its design.
Microarchitectures
- Multicycle microarchitectures are still popular in embedded systems.
Virtual Memory
- Virtual memory is a memory management technique in computing that allows a computer to use more memory than is physically available.
- It uses a memory management unit (MMU) to map memory addresses from virtual to physical.
- Virtual memory makes main storage appear to a process or task as a larger contiguous block of memory than is actually available.
- The operating system manages virtual memory by allocating and deallocating memory spaces as needed.
- The operating system can utilize hard disk storage to extend virtual memory capabilities.
