What fetches and decodes instructions in a computer?
An instruction cycle.
What fetches decodes executes and stores?
the ram
Difference between microprocessor and instruction code?
difference between micro operation and microinstruction
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.
What are the four distinct actions that a machine instruction can specify?
• The processor fetches the instruction from memory • Program counter (PC) holds address of the instruction to be fetched next • PC is incremented after each fetch • Fetched instruction loaded into instruction register
What is the part of a computer that gives directs nstructions?
The instruction unit (decodes and sends commands to alu of the cpu)
