Write code to multiply the contents of the B register by 77. (2 instructions.) Based on your code, in which register would you expect to find the most significant byte of the product?
Write code to divide the contents of the A register by 10. (2 instructions.) Based on your code, in which register would you expect to find the remainder?
Homework Answers
MOV A,#77H;
MUL AB
the result of the of the code will be stored in the register A,
therefore the most significant byte of the product is stored in register A.
MOV B,#10;
DIV AB;
the result of division has two parts:
quotient and remainder
Register A will hold quotient and Register B will hold remainder.

Write MIPS code for each of the following instructions, Your assembly should implement the C code directly – i.e.,do not ’optimize’ the C code to change the order of operations or reduce computations. Use commands only like add, sub, lw, sw, immediate Part 1. x = 3-13*x; Do not use multiply. One way of doing the multiply without a multiply instruction is by using many add instructions (x+x+...+x). For this problem, you should do it with fewer additions. Hint: We...

MIPS ASSEMBLY PROGRAM: PLEASE Write in MIPS Assembly language. Take strings as input and calculate and print a simple checksum for each string. Make your string long enough to hold 50 characters. Don't forget to leave space for the null byte. Our checksum algorithm will produce a value which you can print with the syscall for printing a character. Stop reading strings when the user enters ".". The syscall to read a string (sycall code 8) adds a newline to...
