摘要： A proximity sensor system includes a sensor matrix array having a characteristic capacitance on horizontal and vertical conductors connected to sensor pads. The capacitance changes as a function of the proximity of an object or objects to the sensor matrix. The change in capacitance of each node in both the X and Y directions of the matrix due to the approach of an object is converted to a set of voltages in the X and Y directions. These voltages are processed by digital circuitry to develop electrical signals representative of the centroid of the profile of the object, i.e, its position in the X and Y dimensions. Noise reduction and background level setting techniques inherently available in the architecture are employed.

摘要： Methods for recognizing gestures made by a conductive object on a touch-sensor pad are disclosed. Tapping, pushing, hopping, and zigzag gestures are recognized by analyzing the position, pressure, and movement of the conductive object on the sensor pad during the time of a suspected gesture, and signals are sent to a host indicating the occurrence of these gestures. Signals for compensating for unintended motion of the conductive object on the touch-sensor pad during the gestures are also sent to the host.

摘要： Methods and apparatus are provided for allowing efficient clock domain crossing management in programmable chip systems. Components associated with different clock domains can be analyzed. Clock domain crossing components are automatically selected from a library of clock domain crossing components to allow connection between disparate clock domains. Clock domain crossing components can be shared, chained, and intelligently selected for increased efficiency.

摘要： Methods and apparatus are provided for allowing a master component such as a processor on a programmable chip to access memory using unaligned addresses. An adapter connected to a master component determines if a master component memory access request is aligned. If the access request is aligned, the request is forwarded to memory and a response is provided to the master component. If the access request is unaligned, the adapter sends multiple access requests to memory and processes the responses in order to provide a correct response to the master component.
