1.1 System Architecture Flashcards
1
Q
What is a register
A
A piece of memory in the CPU that does one task
2
Q
What are examples of a register in the CPU
A
- MAR(Memory Address Regester)
- MDR(Memory Data Register)
- ACC(ACCumulator)
- ALU(Arithmetic Logic Unit)
- RAM(if you don’t know this you are in trouble )
3
Q
What does CPU mean
A
Central processing unit
4
Q
What are the 3 c’s that effect CPU speed
A
- Clock speed
- Cache size
- Core number
5
Q
What cycle does the CPU do
A
Fetch execute cycle
6
Q
What concept did Von Neumann come up with
A
Stored program concept
7
Q
What is the Von Neumann “stored program concept”
A
A program and its data are stored in RAM
8
Q
Why is the stored program concept so important
A
Because the CPV can’t access secondary storage
9
Q
What is an embedded system
A
A computer, built into a larger system, that performs 1 specific task
10
Q
What doses the control unit (cu) do
A
Keeps all the registers in time with the clock
