Assume that we want to make the following modifications on MIPS instruction set architecture. Please discuss the impact of these changes on the instruction format of the MIPS architecture. Change 1: Increase the number of registers to 128 Change 2: Support four times as many different instructions (Note that the total number of bits necessary to encode an instruction after the given changes may exceed 32-bit) a) For each of the changes given above, show the size of the bit fields of an R-type format instruction. change 1: change 2: b) For each of the given changes above, show the size of the bit fields of an I-type format instruction. change 1: change 2: c) Do you see any scenario in which the given changes above could decrease the size of a MIPS assembly program? Please, explain how. d) Do you see any scenario in which the given changes above could increase the size of a MIPS assembly program? Please, explain how.
