摘要： A method for discarding perpetually-rejected packets in a fabric-based interconnect having a reliable physical layer is disclosed. A transmitting component keeps a count of the number of negative acknowledgements (NAKs) it receives from the receiving component for packets the transmitting component sends. If the transmitting component receives a number of consecutive NAKs for the same packet that exceeds some pre-determined threshold, the packet is not resent, but is, instead, treated as having been acknowledged, and subsequent packets are allowed to be transmitted. Higher-level processes are then notified of the problem so as to allow the error to be dealt with at a higher level, but without obstructing the flow of packets on the physical layer.

摘要： Disclosed is an adaptive method for training a source synchronous parallel receiver. The adaptive method for training, or aligning, parallel data channels permits a parallel communication receiver to adaptively adjust the timing of data channels to align the data channels with a frame channel and achieve a source synchronous signal for the parallel data channels. Further, portions of the frame channel training pattern may be used because possible time shift accuracy error is accounted for between the communication channels and a determination is made as to which portion of the frame pattern is currently being received. The data channels are then aligned appropriately.

摘要： Disclosed is a method for minimizing the buffer size of an elasticity FIFO queue when synchronizing data between two clock domains. Data communication is typically sent by a transmitter device to a receiver device. The transmitted data signal includes an embedded clock signal and null data characters, as specified by the data communication signal protocol. A null character indicates an empty data frame and is included as part of most standard communication protocols. An embodiment skips one or more null characters from the elasticity FIFO queue during a single clock cycle when it is detected that the write pointer is catching up to the read pointer. By skipping multiple null characters during a single write cycle, the read pointer is moved ahead by one or more queue locations and the write pointer is insured to not catch up to the read pointer for a wider variation in frequencies between a transmitter and receiver than is normally possible. Typically, the elasticity FIFO queue size must be increased in order to support a larger frequency variation. By reducing the need to increase the elasticity FIFO queue size, the gate count and area needed for the elasticity FIFO queue on the silicon chip of the receiver is reduced, thus, reducing the cost contribution of the elasticity FIFO queue to the receiver device. Skipping null characters also reduces the latency time between a write and the associated read of a non-null data character.

摘要： Disclosed is a method for reducing latency between two clock domains in a digital electronic device. The time between a write to a queue position and a corresponding read of the queue position is reduced by up to one clock cycle by including a delay in the time before first writing data to a First In First Out (FIFO) queue used to buffer and synchronize data between two clock domains. The two clock domains have the same frequency, but may be out of phase. Reducing the latency between the write and the corresponding read reduces the required size of the FIFO queue and also results in more efficient system operation.

摘要： A logical gate and a comparator are used to detect page boundaries in a data stream. A current address and a predetermined page size, that is an integer power of 2, are compared using a Boolean logic gate such as AND or XOR to detect a page boundary in a data stream. The output from the Boolean logic gate is compared to a predetermined value to cause a signal to be generated, indicating the end of the page.

摘要： Methods of leveling ink on substrates and apparatuses useful in printing are provided. An exemplary embodiment of the methods includes irradiating ink disposed on a surface of a porous substrate with radiation emitted by at least one radiant energy source. The radiation heats the ink to at least a viscosity threshold temperature of the ink to allow the ink to flow laterally on the surface to produce leveling of the ink. The ink is heated sufficiently rapidly that heat transfer from the ink to the substrate is sufficiently small during the leveling that ink at the substrate interface is cooled to a temperature below the viscosity threshold temperature thereby preventing any significant ink permeation into the substrate.
