The present invention provides an integrated circuit comprising a system bus to which a processor is connectable, and first and second peripheral buses to which peripheral units used by said processor are connected, the first peripheral bus operating at a higher clock speed than the second peripheral bus. Further, the integrated circuit comprises bridge logic for providing an interface between the system bus and the peripheral buses to enable signals to be passed between the system bus and the peripheral buses, the bridge logic comprising clock resynchronisation logic for synchronising the system bus and the peripheral buses. Through the provision of first and second peripheral buses operating at different clock speeds, the integrated circuit of the present invention provides a great deal of flexibility for reducing the power consumption of the integrated circuit as compared with a similar integrated circuit having only one peripheral bus. Since the power consumption of each peripheral bus is proportional to the clock frequency and capacitance, significant power consumption savings can be realised by ensuring that each peripheral unit is connected to the slowest peripheral bus appropriate for that peripheral unit.

An information handling system's thermal management is selectively altered by coupling a thermal barrier to the bottom surface of the information handling system chassis so that an air channel insulates against the passage of thermal energy from the bottom surface. A vent opening in a side of the thermal barrier allows airflow through the air channel to a vent opening of the information handling system. The airflow through the air channel cools the base of the thermal barrier so that an end user will experience reduced thermal energy if the information handling system rests on the end user, such as in the end user's lap.

An LRU array and method for tracking the accessing of lines of an associative cache. The most recently accessed lines of the cache are identified in the table, and cache lines can be blocked from being replaced. The LRU array contains a data array having a row of data representing each line of the associative cache, having a common address portion. A first set of data for the cache line identifies the relative age of the cache line for each way with respect to every other way. A second set of data identifies whether a line of one of the ways is not to be replaced. For cache line replacement, the cache controller will select the least recently accessed line using contents of the LRU array, considering the value of the first set of data, as well as the value of the second set of data indicating whether or not a way is locked. Updates to the LRU occur after each pre-fetch or fetch of a line or when it replaces another line in the cache memory.

A method and system for relative positional tracking of a signal source is disclosed that requires no phase synchronization between the tracked source and tracking system. A signal source transmits a repeating signal. The virtual wavelength of the repeating signal establishes zones of coverage. The system's sampling rate (or sync clock) corresponds to the frequency of the repeated signal. One or more ultrasonic transceivers placed within the desired coverage area capture the transmitted signal. Before tracking begins, a coordinate system origin (X=0, Y=0, Z=0) is established so that all tracking calculations are relative to the origin. Relative time-of-flight measurements are made by comparing the received signals against a sync clock. Tracking is accomplished by triangulating distance measurements received from the ultrasonic transceivers.

Variable rate display interfaces are disclosed. In an exemplary aspect, a high-speed reverse data transfer is enabled over plural lanes of a display serial interface (DSI) bus during blanking periods. Further increases in bandwidth of each high-speed reverse data transfer may be achieved by increasing DSI clock speed during the blanking periods. Since a display relies on a host clock to send reverse data, the frequency of the reverse data is increased, which effectively increases the bandwidth of reverse channel lanes. By increasing the reverse bandwidth over existing pins in the DSI bus, more data may be transferred to the host, including raw touch / stylus data rather than processed data. The raw data may then be processed by the host's relatively powerful processors. By shifting the processing to the host, the need for a powerful touch screen controller (TSC) and / or a powerful touch display driver integrated circuit (TDDI) may be avoided.
