Sign extend in mips

Web--- Notes: The sign-extension logic modeled by BFD is an integral part of the MIPS64 architecture spec. It appears in the virtual address map, where sign extension allows for 32-bit compatibility segments [1] with 64-bit addressing. 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).
