Abstract:
A device for classifying input data, comprising:a first memory unit that stores a first maximum data value and a first minimum data value, wherein said first maximum data value and said first minimum data value define a first data range; and a first comparison circuit that inputs first data, said first minimum data value, and said first maximum data and determines a first relationship between said first data and said first data range, wherein said first comparison circuit outputs a first comparison signal based on said first relationship, wherein said first data corresponds to at least a first portion of said input data, wherein said first comparison signal corresponds to a classification of said input data, and wherein said first comparison circuit comprises: a first programmable comparator that compares said first minimum data value and said first data and outputs said first comparison signal based on a relationship between said first minimum data value and said first data; and a first opcode memory unit that is coupled to said first programmable comparator and that stores an opcode, wherein said first opcode memory unit instructs said first programmable comparator to operate in a first comparison mode when said opcode has a first opcode value and instructs said first programmable comparator to operate in a second comparison mode when said opcode has a second opcode value.
