Abstract: A method for determining a steering wheel angle of a vehicular steering system includes determining a center position for the steering sensor output every time the vehicle is started.  The method employs the use of a yaw sensor for computing an estimate of the actual steering position so that a center position may be back computed to provide immediate and accurate steering position data using the steering sensor signal for controlling an automotive device.  The accuracy of the initial estimates may be improved upon by implementing interim and final center algorithms as vehicle operating characteristics permit.

Abstract: A method and an apparatus for writing and reading display data (213) to and from a FIFO (205). A memory controller (203) retrieves display data from the memory and writes the retrieved data to a FIFO. An output display controller (207) generates a FIFO read signal (211) which is received by the FIFO and in response to the FIFO read signal the display data entries are sequentially read from the FIFO and transferred to an output display. A programmable memory circuit (237) stores a value pointing to a particular display data entry in the FIFO. This value is chosen to minimize the occurrences of overflow (241) and underflow (239) conditions in the FIFO. The present apparatus has the capability to dynamically adapt to different computer system configurations having different frequencies of a system clock (217) and video clock (219).
