Abstract: A method and apparatus are provided for navigating source code (112) by capturing a program trace data history (134) from a target (150) in response to execution of application executable code (123) thereon and decorating the source code blocks (252) on a graphical user interface viewer (251) by displaying an execution instance control indicator (253-255) corresponding to each detected execution instance, where an execution instance control enables control of which execution instance is displayed and an execution instance indicator displays information about the sequence of instructions that were executed at runtime in that execution instance.

Abstract: An apparatus comprising: a lower-layer decoder configured to decode a data stream formatted according to a lower-layer protocol that interleaves portions of a first data stream and one or more additional data streams to produce separated data streams comprising the first data stream and separately the one or more additional data streams; and a higher-layer decoder configured to decode the first data stream formatted according to a higher-layer protocol to produce trace data, the higher-layer decoder comprising: synchronization logic configured to process the first data stream to detect a data pattern within the first data stream as a synchronization event; and decoding logic configured to use the synchronization event to synchronize decoding of the received first data stream to produce the trace data.

Abstract: A tone relay system comprises a tone detector arranged to receive a sequence of signal samples and to provide a plurality of media descriptors, each media descriptor comprising a cell of one or more of the signal samples and a tone detection meta-information for the cell; and a tone relay module arranged to receive each media descriptor, to perform an evaluation of the meta-information and modify the meta-information depending on one or more preceding media descriptors when a result of the evaluation indicates an undetermined tone state, and to provide the media descriptors with a predetermined delay to a tone aggregator module, when the meta-information indicates a tone, for transmission over a network, and to provide the media descriptors without the predetermined time delay to an encoder module, for transmission over the network, otherwise.
