Is it possible to use the jump (j) MIPS assembly instruction to set the PC to the address as 0x4000 0000? Is it possible to use the branch-on-equal (beq) MIPS assembly instruction to set the PC to this same address? no and no 2.40 If the current value of the PC is 0x00000000, can you use a single jump instruction to get to the PC address as shown in Exercise 2.39? No, jump can go up to 0x0FFFFFFC. 2.42 If the current value of the PC is 0x1FFFF000, can you use a single branch instruction to get to the PC address (0x20014924) as shown in Exercise 2.39? Apply the equation we use to calculate branch target T = C + 4 + 4 * D where T = The address of the instruction we want to branch to C = Address of current instruction (the branch instruction) D = displacement in the branch instruction Normally, knowing T and C, we would solve for D. Instead, here we find the most positive and most negative values of D and use them to find the maximum range of addresses we could branch to, starting from C. 17:12:58 7/21/19 C:\USR\TC\CLASSES\CS281\HOMEWORK\ASSIGNMENTS\H-02\H-02-WrittenAssignment-Solutions.wpd 1/2
