1. An especial processor has to be designed based on Accumulator architecture with the following specifications. The processor should access up to 64Kbyte memory and have a maximum of 32 instructions with three different addressing modes. Indicate all necessary fields in the instruction formats and their width in bits when answering the following questions. (i) What do you suggest as the instruction formats for different instruction categories: arithmetic and logic operations, data movement operations and branching operations? Justify your answer and give examples for each instruction category. (8 marks) (ii) Show how the instructions of this processor stored in the byte organized memory. (3 marks) (iii) Describe which type of control unit (Hardwired or Microprogrammable) is suitable for this processor. Give reasons. (5 marks) (iv) What are the steps that you follow to design the control unit of the processor? (4 marks) 1.
