System-on-chip with master/slave debug interface

Abstract

A System-on-Chip (SOC) debugging system comprising a plurality of SOCs connected to a shared bus, at least one of the plurality of SOCs being a master SOC and comprising a master/slave debug interface, wherein the master/slave debug interface is a bidirectional debug interface configured to initiate transactions on the shared bus and operable to send and receive debug data between the SOCs, wherein the debug data comprises trace data.

Dependencies are inferred from the claim text.
