Today we're looking at the purpose of the CPU, specifically the following parts from the OCR Computer Science Specification (https://www.ocr.org.uk/images/225975-specification-accredited-gcse-computer-science-j276.pdf)
the purpose of the CPU
Von Neumann architecture:
- MAR (Memory Address Register)
- MDR (Memory Data Register)
- Program Counter
- Accumulator
common CPU components and their function:
- ALU (Arithmetic Logic Unit)
- CU (Control Unit)
- Cache
the function of the CPU as fetch and execute instructions stored in memory
clock speed
