Functions and characteristics of the CPU Flashcards
How does Clock Speed affect performance?
The clock speed indicates how fast the CPU can run. Therefore if the
clock speed is slow then so will the computer.
How does Cache Size affect performance?
The larger the cache size, the faster the data transfer and the better the CPU performance.
How does Number of cores affect performance?
The number of cores can affect the performance of the computer because a core fetches
and decodes instructions. So if you add more than one it will increase the speed of
performance and mean that it will help create a faster computer system.
What is the Von Neumann theory?
The Von Neumann architecture is a theoretical computer design based on the
concept of stored-program where programs and data are stored in the same memory.
What happens during Fetch?
The first step the CPU carries out is to fetch some data and instructions
(program) from main memory then store them in its own internal temporary memory areas.
What happens during Decode?
Each make of CPU has a different instruction set. The CPU decodes the
instruction and prepares various areas within the chip in readiness of the next step.
What happens during Execute?
The instruction is carried out upon the data .The result of this processing is stored in another register. Once the execute stage is complete, the CPU sets itself up to begin another cycle once more.
what is the fetch decode execute cycle?
The instruction cycle (also known as the fetch–decode–execute cycle ) is the cycle which the central processing unit (CPU) follows from boot-up until the computer has shut down in order to process instructions.
What embedded system does a camera use?
digital image sensor usually either a CCD or CMOS sensor
array that operates with visible light.
What embedded system does a car use?
The embedded system in automobiles is the navigational system using GPS system.
