Abstract
A data processing system is provided with a digital signal processor which has an instruction for expanding one bit to form a mask field. In one form of the instruction, a first bit from a two-bit mask in a source operand is replicated and placed in an least significant half word of a destination operand while a second bit from the two-bit mask in the source operand is replicated and placed in a most significant half word of the destination operand. In another form of the instruction, a first bit from a four bit mask in a source operand is replicated and placed in a least significant byte of a destination operand, a second bit from the four-bit mask in the source operand is replicated and placed in a second least significant byte of the destination operand, a third bit from the four-bit mask is replicated and placed in a second most significant byte of the destination operand and a fourth bit form the four-bit mask is replicated and placed in a most significant byte of the destination operand.
