1.1.2 Factors that affect the performance of the CPU
I'll be discussing the 3 factors that affect the performance of the CPU, specifically :
- The clock speed
- The Cache size
- The number of cores
If you have any questions feel free to message me here:
1.1.1 The purpose of the CPU
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
Podcast intro
This short episode is a welcome session to discuss what I will be covering (and what I won't) and a task for you to get hold of a copy of the topic list (from the OCR website) so you know what order the topics I will be covering over the coming weeks.
Link is here for your information: https://www.ocr.org.uk/images/225975-specification-accredited-gcse-computer-science-j276.pdf
Print it out and get highlighting and I'll be back next week with the first topic episode.
Send me a voice message to ask any specific questions and I may include your questions in future episodes
