ISA Design Tradeoffs. We are designing an ISA based on MIPS with the following changes: the number of possible non-R type instructions is quadrupled. The instruction width remains 32 bits. (a) Assuming the shamt uses the same number of bits, how many different R-type instructions can be en- (b) What is the maximum distance in number of instructions between a J-type jump instruction target and ven its previously expected next instruction?
