20100235156Automated Simulation Fabric Discovery and Configuration - A configuration manager identifies a first device and a second device within a simulated system. Each device within the simulated system includes an inbound port and an outbound port. Next, the configuration manager injects a simulation only packet on the first device's outbound port and detects that the second device's inbound port receives the simulation only packet. As a result, the configuration manager determines that a direct connection exists between the first device's outbound port and the second device's inbound port. In turn, the configuration manager configures one or more first device configuration registers and one or more second device configuration registers that correspond to the first device and the second device, respectively.09-16-2010
20100235158Automated System Latency Detection for Fabric Simulation - A configuration manager identifies a first device and a second device within a simulated system. Each device within the simulated system includes an inbound port and an outbound port. Next, the configuration manager injects a simulation only packet, at an “outbound time,” on the first device's outbound port and detects that the second device's inbound port receives the simulation only packet at an “inbound time.” As such, the configuration manager identifies a direct connection between the first device and the second device and computes a latency time for the connection. In turn, the configuration manager configures one or more first device configuration registers and one or more second device configuration registers based upon the computed latency time.09-16-2010

A charge pumping circuit is enabled by an oscillator. The charge pump oscillator is enabled by the output of a comparator. The comparator compares an input voltage to a comparator voltage, which is a divided version of the output voltage. The output voltage is referenced to a regulated voltage and the comparison voltage is divided between the two voltages by a resistor divider. The regulated voltage remains flat until the input voltage equals the reference voltage. At that point, the regulated voltage will begin to rise and follow the input voltage. Before the reference voltage is reached, the output voltage equals the input voltage multiplied by the resistor divider ratio. Once the input voltage reaches the reference voltage, the difference between the output voltage and the input voltage becomes a constant.04-21-2011

In one example, a first processor provides a location of a plurality of non-stationary pixels in a current frame by comparing pixel data in the current frame with corresponding pixel data in a previous frame for use by a second processor. The first processor also provides pixel data describing substantially only non-stationary pixels in the current frame, for use by the second processor. The second processor calculates motion vector data for the plurality of non-stationary pixels based on the non-stationary pixel location information and the pixel data describing substantially only non-stationary pixels. The first processor encodes the current frame using the motion vector data for the plurality of non-stationary pixels from the second processor.02-02-2012
