Inside The CPU Flashcards
CPU consists of…
Integrated circuits in the microprocessor 🙀
CPU is responsible for..
Processing information and controlling the computer
CPU is the control unit what does it manage…
Execution of the instructions
ALU performs what..
Mathematical and logical computations
Storage locations is called
Registers
Program counter stores…
Location of the current instruction 😝
Control bus
Sends and receives signals that control the CPU and the other parts of the computer system
Address bus
Carries the address of memory locations used to store data and program instructions
Data bus 🚌
Transfers the binary data around the computer
Control unit sends out what to where
Signals to other parts of the computer system
Control unit is responsible for ..
Organising the fetching, decoding and execution of instructions
Instructions registers holds..
The instruction that is currently being executed by the processor 🙂
Accumulator holds…
The accumulated total of results performed in the ALU. Simply keeps track
Program counter holds..
The memory address of the next instruction to be executed
Clock speed what is it ?
Chunk of vibrating cords and sends out impulses
Clock speed how does it impact performance ?
Higher clock speed the faster the computer 💻
Number of cores what is it?
Number if logical processors is the number of CPU’s x number of cores per CPU
Number of cores how it impacts performance?
Can execute steps and split them up making two cores faster then single core.👊🏻
Cache size what is it?
Small area of memory , stores frequently used instructions and places 👐🏻
Cache sizes how does it impact performance?
Speeds up performance when loading 🚶🚶🚶
