6. Given the memory contents of the IAS computer shown below: Address Contents

08A 010FA210FB

08B 010FA0F08D

08C 020FA210FB Show the assembly language code for the program, starting ataddress 08A. Explain what the

7. What general categories of functions are specified by computerinstruction?

8. In a computer, what is a bus, and what does it connect?

9. What is the maximum directly addressable memory capacity inbytes, if the address bus is 16-

bit? Assume each memory location is one byte.

10. Consider a hypothetical 32-bit microprocessor having 32-bitinstructions composed of two

fields, the first byte contains the opcode and the remainder is theoperand address.

a. What is the maximum directly addressable memory capacity inbytes? Assume each

memory location is one byte.

b. How many bits are needed for the program counter and theinstruction register?

11. Briefly define the following states of an instruction executionas shown in Figure 3.6.

a. Instruction address calculation

b. Instruction fetch

c. Instruction operation decoding

d. Operand address calculation

e. Operand fetch

f. Data operation

g. Operand store 12. The hypothetical machine of Figure 3.4 has two I/Oinstructions: 0011 = Load AC from I/O

0111 = Store AC to I/O In these cases, the 12-bit address identifies a particular I/Odevice. Show the program execution

(using the format of Figure 3.5) for the following program:

1. Load AC from device 5.

2. Add contents of memory location 940.

3. Store AC to device 6. Assume that the next value retrieved from device 5 is 3 and thatlocation 940 contains a value of 2. 13. Count from 1 to 2010 in the following bases: a. 8, b.5

20. Assume numbers are represented in 8-bit twos complementrepresentation. Convert to binary

and show the calculation. Also indicate if the operation results ina carry bit, and/or if it is a case

of overflow.

a. 6 + 13 b. -6 + 13 c. 6 – 13 d. -6 – 13

21. Find the following differences using twos complementarithmetic. Also indicate if the operation

results in a carry bit, and/or if it is a case of overflow.

a. 111000 b. 11001100 c. 111100001111 d. 11000011
