1. Draw the functional block diagram of SAP-I architecture and also discuss the main difference with SAP-II. 2. Write a program in SAP-1 using the mnemonics that will display the result of 4+5-2. Use addresses AH, BH and FH for data. 3. Briefly describe instruction set. Also discuss the use of bi-directional registers 4. Briefly describe the functions of various registers in SAP-1 architecture 5. Suppose we want to transfer the data from memory to B register. We need a new instruction, say OMB (Out Memory data to B register). What are the complete SAP-1 microinstructions for this? Express your answer in hexadecimal and binary form. 6. In SAP-II, all the register output to the W-bus are three states, but those not connected to the bus are two states, why? 7. What are the SAP-1 microinstructions for the LDA routine and for the SUB routine? Express the answers in binary and hexadecimal form. 8.
