Abstract
By handling initial processing of HDLC frames, an HDLC engine can free up a server microprocessor that would otherwise be tasked to respond to incoming frames. Sharing a memory with the microprocessor, the engine periodically accesses an address status table in the memory to retrieve data in order to process received frames based on the status of the frame address.
