What part in the computer Fetches and decodes instruction?
The part of the computer that fetches and decodes instructions is the Central Processing Unit (CPU), specifically within its control unit. The control unit retrieves instructions from memory, decodes them to understand what actions are required, and then sends signals to other components of the computer to execute those instructions. This process is fundamental to the operation of a computer, enabling it to perform tasks efficiently.
What fetches instructions from memory decodes them and process them?
Control Unit
Instruction cycle with indirect?
In an instruction cycle with indirect addressing, the CPU fetches the instruction, decodes it to determine the memory address of the operand stored in a register, fetches the operand from the memory location pointed to by the register, and executes the instruction using the operand. Finally, the CPU stores the result back in memory if needed. This extra step of fetching the operand based on the indirect memory address adds complexity to the instruction cycle.
What component fetches instructions from memory decodes them and processes them?
My ball sack
What happens after the microprocessor completes an instruction?
It fetches the next instruction.
What do you understand by programming model of a microprocessor?
Micro-Processor programming model refers to the Micro-Processor system as seen by a programmer. It involves the following: The Instruction Set - The Micro-Processor internal Registers - The way Micro-Processor accesses the memory (Addressing - Mode): Micro-Processor 'Fetches' (reads) an instruction from memory, 'Decodes' (interprets) the instruction, and then 'Executes' (carries out the task) the instruction. It repeats the cycle for next instruction. By Fijabi Isaac M. Tech Computer Sc.
I-time and e-time definition?
I-Time: In I time CU fetches an instruction from memory and place it in register. E-Time: In E time CU fetches an instruction from memory to register and place it in the Arithmetic Logic Unit.
What is the use of instruction decoder?
Instruction decoder takes bits stored in the instruction register and decodes it and tells to CPU what it need to do for it and enable the components for the operation. Simply, instruction decoder is like a dictionary. It tells the meaning of the instruction.
How many times does the CPU need to refer to memory when it fetches and excutes an indirect addressing mode instruction if the instruction is a branch?
In indirect addressing mode for a branch instruction, the CPU typically needs to refer to memory twice. First, it fetches the address of the target instruction from the memory location specified by the operand. Then, it uses that fetched address to access the actual target instruction in memory. Thus, the total is two memory accesses for executing an indirect branch instruction.
