Abstract: In an embodiment, a transmitter includes a transmission path configurable to generate first pilot clusters in response to a matrix, each first pilot cluster including a respective first pilot subsymbol in a first cluster position and a respective second pilot subsymbol in a second cluster position such that a vector formed by the first pilot subsymbols is orthogonal to a vector formed by the second pilot subsymbols, the matrix having a dimension related to a number of cluster positions in each of the first pilot clusters. For example, where such a transmitter transmits simultaneous orthogonal-frequency-division-multiplexed (OFDM) signals (e.g., MIMO-OFDM signals) over respective channels that may impart inter-carrier interference (ICI) to the signals due to Doppler spread, the pattern of the pilot symbols that compose the pilot clusters may allow a receiver of these signals to estimate the responses of these channels more accurately than conventional receivers.

Abstract: Resources of multiple systems are managed in a computer device. A first processing system having a set of dedicated resources also has a resource manager to manage at least one of the resources. The first processing system is prevented from directly accessing the resources without authorization. A second processing system, connected to the set of dedicated resources, has a supervisor application to grant control to individual resources to the resource manager of the first processing system. A computer program is executed in the first processing system. The supervisor application grants control of at least one resource to the resource manager of the first processing system in a way that is transparently to the computer program executing in the first processing system.

Abstract: A start/stop condition detection circuit is coupled to receive the SDA and SCL signals from an IIC Bus. The circuit generates a first signal in response to an edge of the SDA signal and generates an inversion of the first signal as a second signal in response to an opposite edge of the SCL signal. The first and second signals are logically combined to generate an output signal. The particular directions of the edges of the SDA and SCL signals that the circuit is response to determines whether the output signal is indicative of a start condition detection or a stop condition detection.
