- 2What is the purpose of the CPU?To process data:
- Searching
- Sorting
- Calculations
- Decisions
Note: FDE cycle is also key in the CPU - 3In the Von Neumann there is: MDR, MAR, Program Counter and the Accumulator What are their jobs?- MAR (Memory Address Register): Holds the address of the instructions being processed.
- MDR (Memory Data Register): Temporary storage for instruction.
- Program Counter: Stores the memory address of the next instruction. Increments after FDE cycle.
- Accumulator: Temporarily stores data while calculations are being worked out. - 4Common CPU components and their functions are..?ALU: completes all calculations (logic or arithmetic)
CU: controls data movement and executes instructions.
Cache: small but fast type of RAM
