gr-eventstream is a set of GNU Radio blocks for creating precisely timed events and either inserting them into, or extracting them from normal data-streams precisely. It allows for the definition of high speed time-synchronous c++ burst event handlers, as well as bridging to standard GNU Radio Async PDU messages with precise timing easily. http://deepsig.nl

# # Copyright 2017 Tim O'Shea # This directory contains the GNU Radio Eventstream Out-of-Tree Synchronous Stream-Event Scheduler These blocks are intended to help improve the translation of streams of data items into scheduled-finite length events occurring in the data streams in both directions. * es.sink provides the translation from stream to events * es.source provides the translation from events to streams * triggers cause events to be scheduled in es.source and es.sink block event queues. Some examples of specific triggers included are, - es_trigger_edge_f: cause an event when float stream rises above a fixed threshold value - es_trigger_sample_timer: cause an event to occur on a periodic sample increment in the stream * handlers consume events and do some ammount of signal processing on them Some example of specific handlers included are, - es_handler_print: print the event to STDOUT - es_handler_pdu: convert the event to a PDU and send it out a message port - es_handler_insert_vector: a source handler which populates an event window from a PMT vector - es_handler_file: a sink handler which writes event contents out to a file
