Parallel Sum of Absolute Difference InstructionParallel Sum of Absolute Difference Instructionpsad1
Instruction Type I
Format
(qp) psad1 r1 = r2, r3
Description
The unsigned 8-bit elements of GR r2 are subtracted from the unsigned 8-bit elements of GR r3. The absolute value of each difference is accumulated across the elements and placed in GR r1.
