What do Fetch Decode and Execute mean in a microprocessor?
Fetch Decode Execute. This is the cycle that processors will follow. Fetch the Instruction, Decode it into machine code, Execute the commands
What is memory cycle in CPU?
fetch decode exec store
What is a CPU cycle?
The sequence of steps that a CPU performs.Also known as fetch-decode-execute cycle.
What cycle is used by the CPU to execute instructions in a programs?
fetch,decode
Is fetch decode execute cycle is used in coding?
No. Fetch-decode-execute is a machine state time paradigm, not a philosophy used in coding.
What are the four steps in the instruction cycle?
1.fetch 2.decode 3.execute
What are the various phases of an instruction cycle Give the micro operation of fetch and decode phases?
there are 4 phases in instruction cyclefetchdecodeexecutestore
How would you describe the fetch execute cycle?
Fetch Execute Cycle A more complete form of the Instruction Fetch Execute Cycle can be broken down into the following steps: 1. Fetch Cycle 2. Decode Cycle 3. Execute Cycle 4. Interrupt Cycle 1. Fetch Cycle The fetch cycle begins with retrieving the address stored in the Program Counter (PC). The address stored in the PC is some valid address in the memory holding the instruction to be executed. (In case this address does not exist we would end up causing an interrupt or exception).The Central Processing Unit completes this step by fetching the instruction stored at this address from the memory and transferring this instruction to a special register - Instruction Register (IR) to hold the instruction to be executed. The program counter is incremented to point to the next address from which the new instruction is to be fetched. 2. Decode Cycle The decode cycle is used for interpreting the instruction that was fetched in the Fetch Cycle. The operands are retrieved from the addresses if the need be. 3. Execute Cycle This cycle as the name suggests, simply executes the instruction that was fetched and decoded

How does a microprocessor decode?
How many machine cycle required for the instance like move a b?
The MOV A,B instruction requires 1 machine cycle and 4 T-states, 3 to fetch the opcode, and 1 to decode/execute it.
Is the word decode a verb?
Yes, "decode" is a verb. It means to convert a coded message into its original form or meaning.
Is decode an abstract noun?
No, "decode" is not an abstract noun. It is a verb that means to convert a coded message into understandable language.
