First Claim
Patent Images
1. A multi-protocol frame filter system, comprising:
- one or more programmable registers configured to store frame filter data;
a receiver configured to receive an incoming frame;
a multi-protocol frame filter coupled to the one or more programmable registers and the receiver, the multi-protocol frame filter configured for;
comparing one or more fields of the incoming frame to the frame filter data, where the one or more fields are indicative of a wireless communications protocol; and
determining, based on the comparing, to accept or discard the frame.

Abstract
Systems, methods and circuits implementing a multi-protocol frame filter are disclosed. In some implementations, one or more programmable registers are configured to store frame filter data. A receiver is configured to receive an incoming frame. A multi-protocol frame filter is coupled to the one or more programmable registers and the receiver. The multi-protocol frame filter is configured for: comparing one or more fields of the incoming frame to the frame filter data, where the one or more fields are indicative of a wireless communications protocol; and determining, based on the comparing, to accept or discard the frame.

9. A method of multi-protocol frame filtering, comprising:
-
programming one or more registers in a wireless transceiver circuit with frame filter data; receiving, by a receiver of the wireless transceiver circuit, an incoming frame; comparing, by a multi-protocol frame filter of the wireless transceiver circuit that is coupled to the one or more registers and the receiver, one or more fields of the incoming frame to the frame filter data, where the one or more fields are indicative of a wireless communications protocol; and determining, based on the comparing, to accept or discard the frame. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A multi-protocol frame filter system, comprising:
-
one or more programmable registers configured to store frame filter data; a receiver configured to receive an incoming frame having one or more fields, the one or more fields being indicative of a wireless communications protocol and including frame type and frame version fields; a multi-protocol frame filter configured to; conduct a first comparison of the one or more fields to the frame filter data; make a determination, based on the first comparison, to accept the frame type or frame version fields; conduct a second comparison, based on the determination, of one or more other fields of the frame to one or more filter rules; and enable a subsequent processing of the frame based on the second comparison indicating that the one or more other fields comply with the one or more filter rules. - View Dependent Claims (17, 18, 19, 20)
