Abstract:

A processor for filtering message traffic between communication systems may include an input buffer storing an input message and an output buffer. The processor may also include a memory interface communicatively coupled to a filter rule table that includes message filter rules for verifying input messages received by the input buffer and build output message rules for constructing output messages based on the input messages received by the input buffer. The processor may additionally include a message filter state machine circuit communicatively coupled to the input buffer that applies the message filter rules to the input message from the input buffer and determines whether the input message conforms to each of the message filter rules. The processor may further include a build output message state machine circuit that constructs an output message based on the input message and causes the output message to be stored in the output buffer.
