PC-relative Addressing (8 points). Why do branches use PC-relative addressing rather than the pseudo-direct addressing that jumps use? [Hint: Remember that neither addressing mode provides direct access to the full 32-bit addressing space.] 4. 5. MIPS ISA Design (8 Points). Going on the principle that "three's a crowd," your boss tasks you with writing a report detailing the feasibility of removing the J-format from MIPS. To write this, you must consider how you would implement the now pseudo instruction, j label. Provide a functionally-equivalent implementation using MIPS ISA instructions that use only the I- and R-formats. PC-relative Addressing (8 points).
