Translate the C expression f = g*23 to MIPs assembly language

Assume that f and g are allocated in s0 and s1.

do not use multiplication instruction.

Expert Solution

Program Explanation

Define the segment for mentioning the data variables/registers
Define registers $s0, $s1, 23, $t0 and $t1 and store them into the CPU with lw command
Define segment where the code will be present
Initialize the output to 0, register t0 to 1 and t1 to 0
Define the .loop segment
Define the Multiplication_loop function
Use beq to check if the multiplier is 0 or not.
Use and operator to get the LSB value when the multiplier is not 0
Use beq to add the multiplicand to the output only if LSB is not zero
Use beq to check if LSB is not zero, and if this satisfies then apply the multiplication shift function
Define Multipliction_do_add function
Immediately add the multiplicand to the result in this case and store it in the output register which is $s1
Define Multiplication_do_shift function
Use sll command to left shift the multiplicand
Use srl to right shift the multiplier
With j command return back to the multiplication loop
Return the output in the $s1 register with jr command.
