Question
Chapter 10, Problem 1P
Program Plan Intro
a.
“MOV” Command:
- “MOV” instruction or command is used to copy the contents from source to destination address.
- The original content remains unchanged in the source location and the duplicate contents are stored in the destination address.
- “MOV” command copies the files or data from source to destination address as long as rung is true.
“N7:13”:
- “N7:13” is an integer word address.
- “N7:13” represents a single word and word number 13 in an integer file 7 where N represents an integer type of file.
Program Plan Intro
b.
“N7:112”:
- N7:112 is an integer word address.
- N7:112 represent a single word and word number 112 in an integer file 7 where N represents an integer type of file.
“MOV” Command:
- “MOV” instruction or command is used to copy the contents from source to destination address.
- The original content remains unchanged in the source location and the duplicate contents are stored in the destination address.
- “MOV” command copies the files or data from source to destination address as long as rung is true.

Light Emitting Diode (LED):
- LED is an output interface.
- LED is defined as a panel display which uses an array of light-emitting diodes as pixels for video display.
- In public transport vehicles, LEDs are used to display destination signs.

Using the mov.w instruction we copy the 16-bit word 0xB612 to the address 0x1C20. You do not need to know any details of the instruction here, all you care is that the word is stored at the given address. (a) What is the byte that is stored in location 0x1C20? (b) What is the byte that is stored in location 0x1C21?
The control signal 'ALUSrc' controls the multiplexor whose output goes into the ALU.
The inputs to this multiplexor are the 'Read Data 2' from the 'Register' block and the
32-bit wide sign-extended offset from the instruction.
If the instruction is a 'load word' (Iw), which of these two inputs will this control signal
propagate to the multiplexor output and hence to the ALU input?
Choose the best answer.
Since the command is a lw, the 'Read Data 2' needs to be propagated to the ALU
Since the command is a lw, the offset needs to be propagated to the ALU
O This is a trick question. There is no need for the sign-extended offset to be input to the ALU
as it only gets data from the registers
Since this is a lw instruction, the ALU does not come into the picture at all as this datapath
goes directly to the Data Memory bypassing the ALU. This is a 'dont-care' situation
