MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -Decode means to parse the instruction to determine its meaning. A typical instruction consists of an opcode and (usually) one or more arguments. These arguments may refer to specific registers or memory addresses or can be immediate values to be used directly during execution.

Detailed explanation-2: -Fetch: involves receiving the instruction from memory. Decode: The fetched instruction is now decoded for conveying to execution.

Detailed explanation-3: -Ans : The instruction cycle consists of four phases: fetching an instruction from memory, decoding the fetched instruction, reading the address from memory, and finally, instruction execution. The computer processor carries it out.

Detailed explanation-4: -The Instruction Decode and Execute stage takes instruction data from the instruction fetch stage (which has been converted to the uncompressed representation in the compressed instruction case). The instructions are decoded and executed all within one cycle including the register read and write.
