msad4 Function

  • Artículo

Compares a 4-byte reference value and an 8-byte source value and accumulates a vector of 4 sums. Each sum corresponds to the masked sum of absolute differences of different byte alignments between the reference value and the source value.

inline uint4 msad4(
   uint _Reference,
   uint2 _Source,
   uint4 _Accum
) restrict(amp);

Parameters

  • _Reference
    The reference array of 4 bytes in one uint value

  • _Source
    The source array of 8 bytes in a vector of two uint values.

  • _Accum
    A vector of 4 values to be added to the masked sum of absolute differences of the different byte alignments between the reference value and the source value.

Return Value

Returns a vector of 4 sums. Each sum corresponds to the masked sum of absolute differences of different byte alignments between the reference value and the source value.
