Abstract: Moving a pointer in a graphical user interface environment is provided. An input comprising an initial delta value determined by a device driver is received from the device driver. The initial delta value is located in a data structure. A new delta value associated with the initial delta value is selected from the data structure. A new position of a pointer in the graphical user interface environment is calculated based on the new delta value. The new position of the pointer is sent to the graphical user interface environment for rendering.

Abstract: Occurrences of a particular event in an electronic device are counted by incrementing an event counter each time a variable number of the particular events have occurred, and automatically increasing that variable number as the total count increases. The variable number (prescale value) can increase geometrically according to a programmable counter base each time the count mantissa overflows. The event counter thereby provides hardware-implemented automatic prescaling while significantly reducing the number of interface bits required to support very large count ranges, and retaining high accuracy at very large event counts.
