ABSTRACT:
Various embodiments of the present invention provide circuits and methods for improved virus processing. As one example, a method for virus processing is disclosed that includes providing a first memory that includes a first set of virus signatures, and a second memory that includes a second set of virus signatures. In addition, a virus co-processor and a general purpose processor are provided. The virus co-processor is communicably coupled to the first memory, and the general purpose processor is communicably coupled to the virus co-processor and to the second memory. A subset of the second set of virus signatures that is not included in the first set of virus signatures is determined. The subset of the second set of virus signatures is processed on the general processor, and the first set of the virus signatures is processed on the virus co-processor.
