Answer:
The program is as follows:
<em>5 INPUT A,B</em>
<em>6 PROD = A * B</em>
<em>7 PRINT PROD</em>
<em>8 TOTAL = A + B</em>
<em>9 PRINT TOTAL</em>
<em>10 DIFF = A - B</em>
<em>11 PRINT DIFF</em>
<em>12 END</em>
Explanation:
This gets input for the two numbers
<em>5 INPUT A,B</em>
This calculates the product
<em>6 PROD = A * B</em>
This prints the calculated product
<em>7 PRINT PROD</em>
This calculates the sum
<em>8 TOTAL = A + B</em>
This prints the calculated sum
<em>9 PRINT TOTAL</em>
This calculates the difference
<em>10 DIFF = A - B</em>
This prints the calculated difference
<em>11 PRINT DIFF</em>
This ends the program
<em>12 END</em>
Answer:
For 32 bits Instruction Format:
OPCODE DR SR1 SR2 Unused bits
a) Minimum number of bits required to represent the OPCODE = 3 bits
There are 8 opcodes. Patterns required for these opcodes must be unique. For this purpose, take log base 2 of 8 and then ceil the result.
Ceil (log2 (8)) = 3
b) Minimum number of bits For Destination Register(DR) = 4 bits
There are 10 registers. For unique register values take log base 2 of 10 and then ceil the value. 4 bits are required for each register. Hence, DR, SR1 and SR2 all require 12 bits in all.
Ceil (log2 (10)) = 4
c) Maximum number of UNUSED bits in Instruction encoding = 17 bits
Total number of bits used = bits used for registers + bits used for OPCODE
= 12 + 3 = 15
Total number of bits for instruction format = 32
Maximum No. of Unused bits = 32 – 15 = 17 bits
OPCODE DR SR1 SR2 Unused bits
3 bits 4 bits 4 bits 4 bits 17 bits
Answer:
The only element visible is the presentation itself.
Explanation:
All of the other options, such as presenter's assistance, is hidden away from the projector, presentation device, etc. You are the only one that can see the window that shows what slide is next, presenter's notes, etc. <u>In other words, whatever you want the audience to see, that is only what they will see and nothing else.</u>
