Abstract
Programmable data recorders are provided in a network semiconductor chip to monitor and record all or portions of data from various interfaces, including the input and output interfaces of network links interfacing the chip. A data recorder is provided for each network link. The data recorders store captured data in storage arrays. Data may be compressed and associated with time stamps to conserve space in the storage arrays. A data recorder manager in the chip may start and stop the data recorders at approximately the same time. The programmable mode of the data recorders determines which interfaces are monitored, the portion of data captured, and the format of the data in the storage arrays.
