2. (20 points) Assume we would like to extend the MIPS architecture to support a larger register file with 256 registers and supporting twice as many instructions. a. How would this architecture change affect the size of each of the bit fields in an R-type instruction? b. How would this affect the size of each of the bit fields in the I-type instruction? C. How could each of the two proposed changes decrease the size of a MIPS assembly program? d. How could each of the two proposed changes increase the size of a MIPS assembly program? 2.
