Question
I need the questions answer with work shown:
1. If a processor addresses a maximum of (2 to the power of 20) bytes of memory, then, what is the maximum number of 16-bit words that can be stored in this memory?
2. Convert the following base 12 number "A1B" to decimal. Assume it is unsigned.
3. If a certain processor has a system frequency of 100 MHz, what is the clock period?
4. Write the code to implement the expression
A = (B + C) * (D + E)
On 3, 2, 1, and 0 address machines. In accordance with programming language practice, computing the expression should not change the value of its operands.
5. Compare the number of memory accesses for data needed to compute the expression by the four machines of question 3. A = (B + C) * (D + E)
6. What must an Instruction specify?
7. Instructions can be devided into 3 classes:
8. What is the meaning of the following RTN statement:
(OP:=12) R[ra] <-----R[rb]+R[rc]:
9. Describe the following RTN statements:
a. IR <31..0>
b. OP<4..>:=IR<31..27>
10. What decimal value does the binary word 1010 1111 0101 0100 have when it represents an:
a. Unsigned integer
b. 2's compliment
Explanation / Answer
1)
1 byte = 8 bits = 23 bits
Given Processor can address max = 220 bytes, so number of bits addressed by processor = 220 * 23 = 223 bits
Now, one word requires 16 bits = 24 bits.
Therefore, Maximum number of 16 bits word that can be stored = 223 bits/24 bits
= 219 words.
2)
"A1B" base-12 = 1463 base-10
3)
Given, frequency = 100 MHz
Clock Period = 1/frequency
Clock period is 0.00000001 sec = 10ns
4)
PUSH D
PUSH E
ADD
PUSH C
PUSH B
ADD
MPY
POP A
