摘要: Methods and apparatuses for computing an absolute difference of two vectors numbers. In one aspect the invention, a method execution by microprocessor in response to receiving single instruction includes: first plurality numbers second numbers; generating simultaneously third numbers, each which is between number The above operations are performed instruction.
