1.1 System Architecture Flashcards
What does CPU stand for and what is it’s function?
Central Processing Unit, It processes all of the data and instructions that make the system work.
What are the common characteristics of the CPU?
Clock speed
Cache Size
Number of cores
How does the Clock speed affect the performance of the CPU?
The higher the clock speed, the greater the number of instructions the CPU can carry out.
How does the Cache size affect the performance of the CPU?
The higher the cache size the faster the CPU can access more data.
How does the Number of cores affect the performance of the CPU?
The more cores a CPU has, the more instructions it can carry out at once.
What is the function of the Embedded system?
A computer built into another larger system.
What are some examples of the Embedded system?
Dishwashers
Microwaves
TV’s
What are the main parts of the CPU
CU(Control Unit)
ALU(Arithmetic Logic Unit)
Cache
What does CU stand for and what is it’s function?
(Control Unit) It executes program instructions by following the cycle.
What does ALU stand for and what is it’s function?
(Arithmetic Logic Unit) does all the calculations.
What is the function of the Cache?
Stores regularly used data so the CPU can access it quickly.
What are the types of Registers?
MAR(Memory Address Register)
MDR(Memory Data Register)
What does MAR stand for and what is it’s function?
(Memory Address Register) holds any memory address that’s about to be used by the CPU.
What does MDR stand for and what is it’s function??
(Memory Data Register) holds the actual data or instruction.
What is the function of the Program counter?
Holds the memory address of the instruction for each cycle.
