NettetIn an ASL operation, the bits are shifted to the left by a certain number of positions, and the sign bit is shifted out of the number. However, in order to preserve the negative value of the number, the sign bit needs to be set again after the shift operation. This is done by shifting in a 1 at the rightmost position. NettetHowever, for hexadecimal the professor wants us to implement it using a circular left shift (in order to perform a left rotation). IE. 0010 1111 0000 1001 + 0010 1111 0000 1001 ----- 0101 1110 0001 0010 We have to do this 4x and then apply a mask to clear all bits from [15:4] in order to print out the ascii value of bits [3:0].
