Quiz submission record for quiz3-1-2 at Tue Jul 6 10:59:10 2004: Your Answer for Question 1: I think it cannot be the same bit pattern. Because the MIPS instructions have each own instructions's bits, so they cannot be same... Your Answer for Question 2: jump-and-link instructions invoke procedures that have no reason to be near the call, and so they normally use other forms of addressing. Hence the MIPS architecture offers long addresses for procedure calls by using the J-type format for both jump and jump-and-link instructions.
