Abstract
A method of controlling data processing logic which causes a data value to be rotated by a number of bits in order to generate a rotated data value; a number of least significant bits of the rotated data value are masked with other bits of said rotated data value not being masked in order to generate a masked rotated data value; a selected bit of said rotated data value are masked with other bits of said rotated data value not being masked in order to generate a bit preset rotated data value; and said sign-extended bit field extracted data value to be generated by subtracting said masked rotated data value from said bit preset data value or said zero-extended bit field extracted data value to be generated by performing a logical exclusive-OR operation with the masked rotated data value and said bit preset data value.
