Abstract
An apparatus comprising a classifier cache, a plurality of variable length decoder circuits and a core engine circuit. The classifier cache may be configured to store one or more compressed classifier streams. The plurality of variable length decoder circuits may each be configured to generate one or more uncompressed classifier streams in response to a respective one of the compressed classifier streams received from the classifier cache. The core engine circuit may be configured to detect one or more objects in a video signal by checking a portion of the video signal using the uncompressed classifier streams.
