Please answer the following questions about multiplication and division: a. Multiplication: If the multiplicand is in register x28, the multiplier is in register x29, and we would like the multiplication result to be in register x8 (higher 32 bits) and x9 (lower 32 bits). Please write the RISC-V instructions for multiplications in the following cases and explain what each line of code does using comments (i.e., using “//”): 1) The values of x28 and x29 are both signed integers; 2) The values of x28 and x29 are both unsigned integers; 3) The value of x28 is a signed integer, and the value of x29 is an unsigned integer. Division: If the dividend is in register x28, the divisor is in register x29, and we would like to have the quotient in x8 and the remainder in x9. Please write the RISC-V instructions for divisions in the following cases and explain what each line of code does using comments (i.e., using “//”): 1) The values of x28 and x29 are both signed integers; 2) The values of x28…

Assume that a mad scientist has created a computer that has 12-bit registers (storage). The most significant bit is the sign bit. He wants to execute the following computation using 12-bit register. 124-435 (Subtract decimal 435 from decimal 124) Use 2's complement method (in binary) to find the result of the above operation in binary system. Then convert the result back to decimal to check your answer. NOTE: Please don't do the subtraction in decimal! Show all the computations in the answer. Paragraph В I +v Add a File Record Audio
this is COmputer machine architecture ! Help me fix the following code as theres an error. what were trying to accoplish; The assignment is to create a MIPS program that corrects bad data using Hamming codes. The program is to request the user to enter a 12-bit Hamming code and determine if it is correct or not. If correct, it is to display a message to that effect. If incorrect, it is to display a message saying it was incorrect and what the correct data is (the 12-bit Hamming code) again in hex. I will be testing only with single bit errors, so the program should be able to correct my tests just fine. You do not need to worry about multiple bit errors. # This program corrects bad data using Hamming codes # It requests the user to enter a 12-bit Hamming code and determines if it is correct or not # If correct, it displays a message to that effect.

Give the binary microinstruction corresponding to each of the following sets of micro-operations. 1.Increment SP by 1. Store the results back in the SP. Load the MAR with the SP goto 0. 2.Load the contents of register IR into MAR; Read from main memory. 3.Perform the Boolean AND of the contents of IR and AMASK; Store the result in register AC. 4.Test the contents of register TIR for its sign bit N; If N is set, got to the microinstruction at address 50; Shift the contents of TIR one bit to the left; Store the result back into the TIR register.
