Volume information analysis module and method thereof

Abstract

A volume information analysis module reads a data by an interface unit. The volume information analysis module uses a compare unit to compare the data. After comparing the data, the compare unit outputs a signal, and then a count unit accumulates result of the comparing according to the signal. A control unit receives a setting signal from a micro process unit to control the interface unit, the compare unit and the count unit. Thereby using the volume information analysis module can accelerate analysis speed and reduce loading of the micro process unit.
