Abstract
A method is provided for reducing data stored in a capture buffer of an interposer circuit during communication of the data over a data link according to a high-speed, layered packet-based protocol for analysis. The method includes performing data integrity checks of the data in real time, and omitting data integrity bits corresponding to the data integrity checks from transaction layer packets (TLPs) and data link layer packets (DLLPs) of the data when the data integrity checks indicate the data is correct; performing acknowledge and negative acknowledge (ACK/NACK) matching in real time to confirm successful delivery of the TLPs of the data using ACK/NACK packets, where the ACK/NACK packets are omitted from being stored in the capture buffer; removing and/or reducing fields in real time from the TLPs and/or the DLLPs of the data; and compressing data payloads of the TLPs and/or the DLLPs of the data in parallel.
