Methods and apparatuses for operating a data processing system

Methods and apparatuses to manage working states of a data processing system. At least one embodiment of the present invention includes a data processing system with one or more sensors (e.g., physical sensors such as tachometer and thermistors, and logical sensors such as CPU load) for fine grain control of one or more components (e.g., processor, fan, hard drive, optical drive) of the system for working conditions that balance various goals (e.g., user preferences, performance, power consumption, thermal constraints, acoustic noise). In one example, the clock frequency and core voltage for a processor are actively managed to balance performance and power consumption (heat generation) without a significant latency. In one example, the speed of a cooling fan is actively managed to balance cooling effort and noise (and / or power consumption).

High bandwidth connector

An improved open pin field connector is provided for enhanced performance when carrying high speed signals by selective application of one or more techniques for controlling electrical performance parameters. Lossy material may be positioned adjacent to conductive elements of the connector so as to reduce resonance in pairs of conductive elements and / or to provide a desired characteristic impedance for pairs of differential signal conductors. The lossy material may be shaped and positioned to avoid capacitive coupling that might otherwise increase cross talk. In a right angle connector, the lossy material may have a step-wise increase in thickness to provide comparable loss along longer and shorter conductive elements. Conductive elements may be shaped to balance performance characteristics of pairs selected to carry differential signals regardless of orientation along a row or column. Alternatively, conductive elements may have narrowed regions, covered with lossy portions, for reducing resonance while supporting DC signal propagation.
