System Architecture Flashcards
What are the 3 main parts in the cpu
Alu
Cu
Memory unit
What is the alu
Responsible for all the arithmetic calculations and logical operations
It also performs binary calculations
The is the cu
The control unit is responsible for the processing of data and instructions . It interprets instructions and sends the correct data to the ALU
What is the memory unit
It is composed of registers which are small individual memory locations.
The memory unit stores the instructions and data input and output
What is a register
A small data holding place that may hold one instruction or storage address
Located in the computer processor
What different types of processor are there
Accumulator, data,address, program counter , memory data, index, memory buffer
How does clock speed affect computers perforamce
This refers to the speed of which the processors can execute instructions
How does cache memory affect a computers performance
The larger the cache size the faster the data transfer
How does number of cores affect a computers performance
It allows the computer to run multiple programs at the same time
What is the accumulator
Where intermediate arithmetic and logic results are stored
What is the CIR
Current instruction register. Contains the current instruction during the processing
What is the program counter
Contains the address of the next instruction
What is the MAR
Memory address register. Holds the location of the data that needs to be accessed
What is the MDR
Memory address register holds data that is being transferred to or from memory
What is an embedded system
An embedded system is a computer system with a dedicated function within a larger mechanical or electrical system
