摘要： The frequency of a clock signal is compared to a predetermined range. If the measured frequency is outside the range, a system controller determines if a current operating state of the overall system allows for the internal clock to be adjusted back into compliance. If the controller determines that the current system state allows for the change, then a control signal to the internal clock signal source is changed by the smallest increment available, either to increase or decrease the frequency. If the internal clock signal is out of the desired range, and the system controller does not decide to modify the frequency, the controller may increase the size of the range by decreasing the lower bound and/or increasing the upper bound.

摘要： An optical receiver includes a reception module, a first detector, a second detector, a shift module, a first extraction module, and a second extraction module. The reception module receives a frame. The first detector detects a head position of a first layer, the head position being included in the frame. The second detector detects a head position of a second layer, the head position being included in the frame. The shift module shifts the frame so that the head position of the first layer and the head position of the second layer are located at respective predetermined positions. The first extraction module extracts a header of the first layer from the frame after the frame is shifted. The second extraction module extracts a header of the second layer from the frame after the frame is shifted.

摘要： Technologies are generally described for measuring clock skew between two remote hosts connected through a computer network. According to some examples, pairs of probe packets, also referred to as a compound probe, may be transmitted over an end-to-end path in both directions (forward and reverse paths) to measure a gap value at the end nodes for clock skew estimation. Compound probes may arrive at the end nodes with a zero dispersion gap (no separation) and the gap values along the forward and reverse paths may be determined by a capacity of the links connected to the end nodes added to the clock speeds of the measuring nodes upon arriving at the end nodes. The link capacity is a constant network parameter. Thus, the ratio of the measured gap values may provide an estimate of clock speed discrepancy between the end nodes.

摘要： Disclosed herein are a deskew apparatus and method for Peripheral Component Interconnect (PCI) Express for compensating for a skew. The deskew apparatus includes a lane data input unit, a lane data alignment unit, and a lane data detection unit. The lane data input unit receives 18-bit data from each of lanes of the PCI Express. The lane data alignment unit aligns the 18-bit data using a COM symbol. The lane data detection unit detects a change in a state of alignment of the 18-bit data attributable to deletion or addition of an SKP symbol when the 18-bit data is aligned, and to perform synchronization between the lanes.
