Abstract: In some embodiments, the inventions includes a transmitter including a cycle encoding circuit to receive a data input signal and to provide a full cycle encoded signal in response thereto by continuously joining portions of different encoding signals. Some of the encoding signals have a different frequency than others of the encoding signals and some of the encoding signals have a different phase than others of the encoding signals. Data is represented in data time segments of the full cycle encoded signal and no data time segment has more than one cycle of an encoding signal. In some embodiments, a receiver receives the cycle encoded signal and recovers data of the data input signal.

Abstract: A fully asynchronous parallel synchronizer having staged write and read enables and an asynchronous interface for same. The asynchronous interface can be used to interconnect two processor systems (e.g., within a multiple processor system or a parallel processor system). The parallel programmable synchronizer contains n latches coupled in parallel having n individual enable lines having staggered enable signals. The latches are coupled such that they output to a multiplexing circuit that also receives individual staggered read enable signals which are based on the write enable signals. According to the parallel programmable synchronizer, data is written into a particular latch in clock cycle (i) just after other data was read from the same particular latch in a just prior clock cycle (i-1). While the synchronizer contains n latches, the number of latches used, x, for any particular embodiment is programmable and the enable signals adjust to accommodate the number of latches selected.

Abstract: An asynchronous interface enabling a processor node operating at a first clocking frequency to transfer and receive information from a communications network operating at a second clocking frequency. The asynchronous interface comprises an input synchronizer and an output synchronizer. The input synchronizer asynchronously receives a first plurality of information packets from the processor node and synchronously transfers the first plurality of information packets into the communications network. The output synchronizer, however, synchronously receives a second plurality of information packets from the communications network and asynchronously transfers the second plurality of information packets into the processor node. Both the input and output synchronizers are coupled between the communications network and the processor node.
