The document discusses the key requirements placed on a processor during instruction execution. A processor must fetch instructions from memory, interpret the instruction to determine the required action, and may need to fetch data from memory or I/O modules to execute the instruction. Understanding these fundamental requirements is important for analyzing the organization of a processor.

 To understand the organization of the processor, let us consider the
requirements placed on the processor, the things that it must do:
 Fetch instruction: The processor reads an instruction from memory
(register, cache, main memory).
 Interpret instruction: The instruction is decoded to determine what
action is required
 Fetch data: The execution of an instruction may require reading data
from memory or an I/O module.
