l" in the subject line. For these programs, you may use ONLY these instructions: and nor or ori sll srl xor Run the programs by verifying the value of the PC is 0x00400000 (if needed, right-click the field and use Change Register Contents to set it) and then single stepping (pushing F10) and observing the results in the QtSpim register display window. Exercise 1: Start with the instruction that puts a single one-bit into the low order bit of register eight ($t0): ori $t0, $zero, 0x01 Now, by using only shift logical instructions and register to register logic instructions (use NO more immediate instructions), put the pattern Ox55555555 into register Stl. You may not use another andi, ori or xori instruction to set another bit from scratch, you must work from the single bit you set in the first instruction or created directly from that bit. You will need to use more registers than just $tl. See how few instructions and registers you need to do this. Doing this in approximately twelve instructions is reasonable. It can be done in fewer. Again, you MAY NOT create any other data bits from scratch for this, only the single bit you started with. Exercise 2: Again, start with the instruction that puts the single one-bit into register eight ($t0): ori $t0,$zero, 0x01 Now, by using only shift logical instructions and register to register logic instructions (use NO more immediate instructions), put the pattern Ox69696969 into register $ti. Don't use another andi, ori or xori instruction. You will need to use other registers than just $ti. See how few instructions you need to do this. Again, this can be done in approximately ten to twelve instructions. Again, you may only work from the one initial bit. Exercise 3: Again, start with the instruction that puts the single one-bit into register eight ($t0): ori $to, $zero, 0x01 Now, by using only shift logical instructions and register to register logic instructions (use NO more immediate instructions), put the pattern OxFFFFFFFF into register $t1. Don't use another andi, ori or xori instruction. You will need to use other registers than just $t1. See how few instructions you need to do this. This can be done in very few instructions. Again, for all of these exercises, you must work from the one initial bit set using the ori instruction. All other on bits MUST be created from that bit or from bits created directly from that bit. You cannot clear the original bit you set, either. It has to stay a 'l. l" in the subject line.
