Unformatted text preview: to support your discussion. 4. What is a virtual machine? Discuss this definition in terms of the Pep/7 computer. 5. We said that you should have guessed that a Pep/7 instruction would use 5 bits when we said that there were 32 instructions. Explain. 6. Describe the features of the Pep/7 CPU that we covered in this chapter. 7. We covered only two of the four addressing modes. If we had not stated this explicitly, could you have deduced that this was true? Explain. 8. Where is the data (operand) if the address mode specifier is a. 00 b. 01 9. Distinguish between the IR (instruction register) and the PC (program counter). 10. How many bits are required to address the Pep/7 memory? 11. How many more cells could be added to memory without having to change the instruction format? Justify your answer....
