1. Functional Requirements

   • Definition: Those functions that the control unit must perform
     • Basic functional elements of the processor
       • Registers
         • Are used to store data internal to the processor.
         • Some records contain necessary status information to manage the instruction sequence.
       • Internal data paths
         • Are used to move data between registers and between Register and ALU.
       • ALU
         • Is the functional essence of the computer.
       • Control unit
