What are the factors affecting the processing speed?
Factors affecting CPU performance
- clock speed.
- cache size.
- number of cores.
What is processor & memory communication?
The Central Processing Unit(CPU) has a Memory Data Register (MDR) and a Memory Address Register (MAR). The Memory Data Register (MDR) keeps the data which is transferred between the Memory and the CPU. The Arithmetic and Logic unit of CPU places the address of the memory to be fetched, into the Memory Address Register.
What ISA full form of ISA?
(ˈaɪsə ) noun acronym for. individual savings account: a tax-free savings scheme introduced in Britain in 1999.
What are the factors affecting the speed of microprocessor of a computer?
Front Side Bus (FSB) Speed The CPU’s FSB speed determines the maximum speed at which it can transfer data to the rest of the system. Other factors affecting data transfer rates include the system clock speed, the motherboard chipset, and the RAM speed.
How does RAM affect the processing speed of a computer?
Generally, the faster the RAM, the faster the processing speed. With faster RAM, you increase the speed at which memory transfers information to other components. Meaning, your fast processor now has an equally fast way of talking to the other components, making your computer much more efficient.
What is the working relation between memory and processing unit of a computer?
The hardware that defines a computer is the CPU and memory . Without these a computer could not function. The CPU and memory work together to run programs. Memory – stores program operations and data while a program is being executed .
How computer architecture affects a language?
Computer architectures and programming languages are traditionally developed indepen d ently. Through suitable computer architecture, for instance, one can attempt to speed up the processing of a stream of data and instructions, leaving to the software the burden of preparing these streams.
How is information sent from the control unit to the processing unit?
The control unit sends them. Likewise, when the time is right, the control unit sends these items from memory to the arithmetic/logic unit, where an arithmetic operation or logical operation is performed. After being processed, the information is sent to memory, where it is hold until it is ready to he released to an output unit.
What happens when a process is swapped out of memory?
When processes are swapped out of memory and later restored, additional information must also be stored and restored. Key among them are the program counter and the value of all program registers. Figure 3.1 – A process in memory 3.1.2 Process State Processes may be in one of 5 states, as shown in Figure 3.2 below.
What happens to program instructions when computer is off?
Memory stores program instructions or data for only as long as the program they pertain to is in operation. Keeping these items in memory when the program is not running is not feasible for three reasons: Most types of memory only store items while the computer is turned on; data is destroyed when the machine is turned off.
How is the ISA implemented in hardware?
The implementation of the ISA in hardware is couched in terms of the fetch-decode-execute cycle illustrated in Figure 2.2. In the fetch step, operands are retrieved from memory. The decode step puts the operands into a format that the ALU can manipulate. The execute cycle performs the selected operation within the ALU.
