Abstract: A microcontroller has a timebase driven by a clock signal, wherein the timebase has a reset input and an output coupled with a comparator. The comparator is further coupled with a register and is operable to generate a synchronization output signal if the timebase matches the register value. The microcontroller further has a first multiplexer receiving the synchronization output signal from the comparator and further receiving at least one event signal generated by a unit other than the timebase, wherein the first multiplexer is operable to select either the synchronization output signal or the at least one event signal as a timebase synchronization output signal.

Abstract: A communication system processes blocks of input data that include control words and a packet of information words are received. The packet has a start preceded by ones of the control words and an end followed by others of the control words. When the block consists exclusively of information words, a one bit block header having a first sense is appended to the block to form a frame. When the block does not consist exclusively of information words, the block is condensed to accommodate a TYPE word, the TYPE word is generated and inserted into the block and a one bit block header is appended to the block to form the frame. When the block does not consist exclusively of information words the one bit block header has a second sense, opposite to the first sense. Use of a one bit block header reduces overhead. Forward error correction is also utilized.

Abstract: A signal processor includes a period detection section which detects that a period is currently used for communication of a frame; a pattern detection section which detects, from the received signal, a first signal pattern by which the end of communication of the frame is recognized; and an output processing section which outputs the received signal to a controller, configured to instruct, upon detection of the first signal pattern in the period being currently used for communication of a frame, the controller to halt startup of communication action of the next frame, until the period being currently used for communication of a frame comes to the end, to thereby reduce an event such that frames are transmitted from a plurality of communication devices simultaneously, and to thereby allow the communication action for the next frame to proceed correctly.

Abstract: A method is disclosed for transmitting a multi-channel data stream comprising frames comprising a plurality of channels, the transmitting being done via a multi-transport tunnel from a first tunnel end-point to a second tunnel end-point, the multi-transport tunnel implementing at least one first carrier supporting a transport protocol with acknowledgement and at least one second carrier supporting a transport protocol without acknowledgement.More specifically, the invention proposes to introduce a delay in the sending of data ( >) via the first carrier as compared with the sending of data ( >) via the second carrier. Thus the invention guarantees the order of arrival of channels that are associated with a same piece of synchronization but are transmitted on distinct first and second carriers and come from the separation of a same multi-channel data frame.
