1. (15 points) The instructions in progress in the MIPS pipeline shown below are unidentified. Your task is to determine as much as you can of the five instructions in the five pipeline stages. If you cannot fill in a field of an instruction, state why. Hint: Try writing as many of the 32 bits of each instruction in binary before writing the instructions in assembly language notation; use the end pages to get the instruction values.
