WebMar 21, 2024 · 5.1: The Sign Extend Unit. The immediate values which can be part of an instruction are 8 bits, and can be used as an input to the ALU. However, the ALU accepts inputs which are 16 bits. Therefore, immediate values which are passed to the CPU must be expanded to fill 16 bits. The question is how to fill in the high 8 bits when expanding ... WebThe immediate operand of this instruction is 16 bits (as are all MIPS immediate operands).

WebFor two's complement representation, the extension consists of replicating the sign, as shown for m = 5 in Figure 3.1. To simplify the description that follows, we place the binary point after the “sign” bit and index as for fractions.

WebApr 3, 2024 · Note the inconsistency: The addition instructions treat the immediate as a signed 16-bit value (and sign-extend it to a 32-bit value), but the bitwise logical operations treat it as an unsigned 16-bit value (and zero-extend it to a 32-bit value). Stay alert! The last group of instructions for today is the shift instructions. These also never trap.

WebWithout the patch below, only 32 bits are being transferred, thus leaving in place the (high 32-bit) sign extension of -1. When the sim attempts to execute the instruction noted above, it first checks to make sure that the sign extension for the register being transferred is sane. It is not, and therefore quits printing the UNPREDICTABLE message.
