摘要: A processing engine for classifying data according to a decision tree having n-nodes is disclosed, wherein each node is represented by a respective test according to which a flag may be set or unset, comprising: a respective test unit and corresponding to each node, having an output flag and being configured to set or unset the respective output flag according to an output of the respective test; a memory configured to hold an n-bit word, each bit corresponding to a one of the respective output flags; and a data-structure configured as a look up table, each entry of the look up table representing a class of the data. Corresponding methods are also disclosed, as are devices and systems incorporating such processing engines.
