Abstract: A system and method for efficiently transporting data across lanes. A computing system includes an interconnect with lanes for transporting data between a source and a destination. When a source receives an indication of a bandwidth requirement change from a first data rate to a second data rate, the transmitter in the source sends messages to the receiver in the destination. The messages indicate that the data rate is going to change and reconfiguration of one or more lanes will be performed. The transmitter selects one or more lanes for transporting data at the second data rate. The transmitter maintains data transport at the first data rate while reconfiguring the selected one or more lanes to the second data rate. After completing the reconfiguration, the transmitter transports data at the second data rate on the selected one or more lanes while preventing data transport on any unselected lanes.

Abstract: An apparatus includes circuitry and an oscillator circuit that may be configured to generate a clock signal dependent upon a control signal. The circuitry may be configured to perform a frequency measurement of the clock signal. In response to a determination that the frequency of the clock signal is greater than a first threshold, the circuitry may also be configured to perform a phase comparison between a divided clock signal and a reference clock signal, and to adjust a value of the control signal such that the adjusted value depends upon a result of the comparison. In response to a determination that the frequency of the clock signal is less than the first threshold, the circuitry may be configured to adjust the value of the control signal such that the adjusted value depends upon a result of the measurement.

Abstract: A method and apparatus for assigning a set of region-based voltage drop budgets to an integrated circuit is provided. Further, a method for partitioning an integrated circuit into optimal voltage drop regions includes analyzing the integrated circuit for worst-case voltage drop data. The worst-case voltage drop data is used to partition the integrated circuit into a set of voltage drop regions, wherein each voltage drop region is assigned a region-based voltage drop budget. The region-based voltage drop budget assigned to a particular voltage drop region is based on a worst-case voltage drop experienced by that voltage drop region.

Logic path segments that reside in different voltage drop regions are tested using a supply voltage inputted by the respective voltage drop region.

Abstract: A temperature monitoring technique that eliminates the need for bipolar devices. In one embodiment of the present invention, a long-channel MOS transistor is configured in a diode connection to sense change in temperature. The diode drives a linear regulator and an oscillator. The oscillator in turn drives a counter, which counts pulses for a fixed period of time. The system clock on the chip is used as a temperature-independent frequency to generate a count. The temperature-dependent frequency is counted for a fixed number of system clock cycles. The present invention eliminates band gap circuitry currently used in most thermal sensing devices to provide a temperature-independent reference.

The device uses a voltage controlled delay element that outputs a reset signal to a flip-flop dependent on a bias signal and the input clock signal.

The duty cycle corrector may be configured to generate the bias signal so as to be able to operatively control the duty cycle of the output clock signal.

Abstract: A clock grid skew reduction technique that uses one or more biasable delay drivers to compensate for unbalanced loading and/or RC wire delay induced skew is provided. The biasable delay driver has a size that may be varied depending on a delay amount of a signal from a clock source to an input of the biasable delay driver. Depending on the delay amount, the biasable delay driver may be either sized up or sized down to modulate delay in order to reduce or eliminate skew between the clock signal at the input of the biasable delay driver and the clock signal at another point in a circuit.
