摘要： In some embodiments, the invention involves a system having a first group of integrated circuits connected in a truncated ring fashion, wherein the truncated ring includes a truncated region to allow for additional integrated circuits to be added to the ring. In some embodiments, the invention involves a system having a group of integrated circuits connected in a pseudo ring fashion, wherein the pseudo ring is created by data flow of bi-directional signaling between the integrated circuits. In some embodiments, the invention involves a system having a group of integrated circuits connected in a pseudo differential arrangement in which multiple conductors carrying signals share a common reference signal conductor.

摘要： For one disclosed embodiment, an integrated circuit may comprise an internal transmission line in one or more layers of the integrated circuit. The internal transmission line may be coupled to receive a signal from an external transmission line at a first end of the internal transmission line without use of termination circuitry. The internal transmission line may transmit the signal passively to a second end of the internal transmission line. The integrated circuit may also comprise first circuitry having an input coupled to the internal transmission line at a first location of the internal transmission line to receive the signal and second circuitry having an input coupled to the internal transmission line at a second location of the internal transmission line to receive the signal. The second location may be different from the first location. Other embodiments are also disclosed.

摘要： Generally, this disclosure provides error management across hardware and software layers to enable hardware and software to deliver reliable operation in the face of errors and hardware variation due to aging, manufacturing tolerances, etc. In one embodiment, an error management module is provided that gathers information from the hardware and software layers, and detects and diagnoses errors. A hardware or software recovery technique may be selected to provide efficient operation, and, in some embodiments, the hardware device may be reconfigured to prevent future errors and to permit the hardware device to operate despite a permanent error.

摘要： A digital bus includes a transmitter unit, a receiver unit, and a transmission medium to couple the transmitter unit to the receiver unit and to provide a path for exchanging information between the transmitter unit and the receiver unit. The receiver unit includes a first-in-first-out (FIFO) unit and a synchronizer unit for receiving information from the transmitter unit. The synchronizer unit receives a plurality of write clock signals and a reset signal and generates a read reset signal positioned with respect to the plurality write clock signals and a sample clock signal. The read reset signal has a latency with respect to each of the plurality of write reset signals of between 0 and 1 clock cycles.
