"WebNote that the cwd (convert word to double word) instruction does not sign extend the word in AX to the double word in EAX. Instead, it stores the H.O. word of the sign extension into the DX register (the notation "DX:AX" tells you that you have a double word value with DX containing the upper 16 bits and AX containing the lower 16 bits of the value).
