Question: Problem 2 ISA Design Assume that we would like to expand the MIPS register file to 128 registers and expand the instruction set to support240

Problem 2 ISA Design Assume that we would like to expand the MIPS register file to 128 registers and expand the instruction set to support240 different R-type of operations. (a) What should be the minimum number of bits needed by R-type of instructions to support these changes? Show your work by indicating the bitwidth of each field for R-type of instructions (1Spts (b) Increasing the number of registers increases the code size. i. Give an argument that shows that this statement is false. (Spts) i. Give an argument that shows that this statement is true. (Spts)
