Macro Library Absolute difference of signed words: computes the absolute difference of two input signed words, which are destroyed Absolute difference of unsigned bytes: output = abs(Input1 - Input2), both Input1 and Input2 are destroyed Absolute value of signed doublewords: stores into Output the absolute value of Input which is destroyed Absolute value of signed words: stores into Output the absolute value of Input which is destroyed Average of unsigned bytes: MMX implementation of the SSE PAVGB instruction: InputDest = (InputDest + InputSrc) / 2 Clear variable: clears input variable Set variable: sets all bits of input variable to 1 Maxima of signed words: mirrors the PMAXSW SSE instruction: returns in the Destination variable the greater value of the Destination and Source variables Maxima of signed bytes: returns in the Destination variable the greater value of the Destination and Source variables Minima of signed words: mirrors the PMINSW SSE instruction: returns in the Destination variable the lower value of the Destination and Source variables Minima of signed bytes: returns in the Destination variable the lower value of the Destination and Source variables
