Sequential feedback HEC checking method and circuit for asynchronous transfer mode (ATM)

摘要

The present invention provides sequential feedback Header Error Correction (HEC) checking method and circuit for Asynchronous Transfer Mode (ATM). With design of hardware circuit, the present invention of sequential feedback Header Error Correction (HEC) checking method and circuit will allocate the cell boundary in ATM communication, and meanwhile control the state switching among three operation for cell delineation logic, i.e., HUNT, PRESYNC and SYNC.
