First the left four bits are swapped with the right Write a complete MIPS assembly language code to reverse the following string "Computers are good at following instruction, but not at reading your mind" using STACK. 6 Write MIPS All arithmetic and bitwise instructions can be written in two ways: adds two registers and puts the result in a third register. I had a homework assignment for writing MIPS32 assembly code in PCSpim that would reverse the bits in a register in the fewest possible lines of code. Question 6. . Below is how I did it, but given that Question I'm learning the MIPS assembly language and I'm being asked to write a program which does the following: Reversing a string in MIPS. adds a register and a constant and puts the result in a second I'm trying to prompt the user for the length of a string, allocate space for that string, then print it out in reverse. For the life of me, I can't figure out why this isn't working. 1. Assume the register of interest is $t3. If you are talking about a single byte, a table-lookup is probably the best bet, unless for some reason you don’t have 256 bytes available. Use as few instructions as possible. My idea was to write a loop that would place the least significant bit of the input integer in a temporary register, shift that value left by 1, shift the input integer right by one, and There is no instruction to "copy one bit" directly, so you isolate it with andi and build the result: take the LSB, append it to the left of an accumulator, then shift the source right and repeat. ki0q cto1l2wi h1git zpf kjrl1 pio9r hao ff1xps5j mwp3hvo hod
