MIPS:
- MIPS stand for Microprocessor without Interlocked Pipeline Stages.
- MIPS instructions have 32-bits general purpose registers.
- The register preceded by “$” in assembly language instruction and it contains two formats for addressing one is register number and another is equivalent names.
- The result of multiplication and division can be stored in the special registers “Lo” and “Hi”.
Example:
Consider an example of MIPS assembly code:
#add the variables and store in “a”
add a, b, c
Here the given instruction tell the computer to add the two variables “b” and “c” and store the result in the “a” variable.

Explanation of Solution
Given statement:
#subtract the values and store in “f”
f = h – 5
#add the variables and store in “f”
f = f + g
Explanation:
Subtract the variable “h” and the value “5” and the result is store it in “f” then the variables “g” and “f” are added and store it in the “f” variable.
Corresponding MIPS assembly code:
#add the constant value with the variable and store in #“f”
addi f, h, -5
#add the variables and store in “f”
add f, f, g
Explanation:
- Here, “addi” instruction is used to add constant values. The variable “h” is added to the “-5” value then store the result in “f” variable.
- The second statement tells the computer to add the two variables “f” and “g” and store the result in the “f” variable.

- Please solve and show all steps. I need to see the Packet Tracer file. Create two subnetworks representing Computer Engineering (CE) and Computer Science (CS) programs. CE subnetwork can use IPs from 169.168.2.0/16 CS subnetwork can use IPs from 170.168.2.0/16 Use the packet tracer program to build your network and make the required configuration to send and receive files between the two programs.arrow_forwardNo AI please.
