... specifies the operationto perform, while the reg1 and reg2 represent the registers to use as operands, and the des field represents the register in which to store the result. For example, the 32-bit ... bits of the result. Therefore, if hi is non-zero after wedo the multiplication, then the result of the multiplication is too large to fit into asingle 32-bit word, and we can detect the error.We’ll ... Set Xi and ˆc according to the following rules:• If s == 0, then Xi= 0 and ˆc = 0.• If s == 1, then Xi= 1 and ˆc = 0.• If s == 2, then Xi= 0 and ˆc = 1.• If s == 3, then Xi= 1 and ˆc...
