Abstract: A system for a pipeline cascaded content addressable memory CAM system for sequentially processing input data includes an input register, a CAM core, cascade logic and an output register. As the memory association functions produce matches in the CAM core, the cascade logic in parallel composites data associated with each matching CAM core. Each cascade processes a separate data input simultaneously then passes on the cumulative results to the next stage.

Abstract: The present invention encompasses a method of storing ternary data that includes the steps of (1) initializing a conversion register by storing binary-to-ternary mask data in a conversion register; (2) storing ternary data in a content addressable memory (CAM) by inputting a single bit binary data to the conversion register, and converting the binary data into two bits of ternary data using the conversion register; and (3) simultaneously storing the two bits of ternary data in first and second memory cells. For subsequent searching, the method further includes the steps of searching for a match of input search binary data to the stored contents of the CAM; providing a match valid output responsive to the input search binary bits matching any of the stored contents; and generating an address corresponding to a location in the CAM where the match is found.

Abstract: A method for monitoring the performance of a catalytic converter (34) computes the oxygen storage capacity and desorption capacity of a catalyst within the catalytic converter (34). An engine control unit (10) receives mass flow rate information of air from a mass air flow rate sensor (12) and an injector driver (24), and receives electrical signals from an upstream exhaust gas sensor (28) and a downstream exhaust gas sensor (30). The engine control unit (10) calculates normalized air fuel ratios for the exhaust gas entering and leaving the catalytic converter (34) and performs numerical integration to determine the oxygen storage capacity and oxygen desorption capacity of the catalyst in the catalytic converter (34). The calculated oxygen storage and desorption capacities of the catalyst are compared with threshold values to determine the performance of the catalytic converter (34).

Abstract: In order to derive accurate DR heading information from the wheel speed, the distance between the centers of the tires, or the wheel track, must be known to high precision. Unfortunately, the wheel track may not always be known to a high level of accuracy whereby different classes of the same vehicle type can produce variations of up to 5 %. This current invention removes the error growth associated with wheel track error by automatically estimating and calibrating the wheel track. The wheel track is measured by computing a heading rate directly from the GPS Doppler measurements, and comparing it with the heading rate derived from the wheel sensors whereby subsequent refinements to the estimated wheel track are computed by filtering each measured track.

Abstract: A selective call communication system (10) transmits a frequency hopped spread spectrum signal as a Reed Solomon code word modulated as a four-level frequency shift keying (4FSK) signal. A base site transceiver (150) receives the signal on a plurality of narrow band channels and a DSP (152) performs an FFT on the signal. The DSP (152) has a comparator (342) that computes energy of a 4FSK symbol. The comparator (342) establishes a ratio of a maximum energy and a next largest energy to an eye-opening threshold to indicate a probability of error. A determinator (344) in response to the probability of error determines when there is a fade, an erasure marker (346) marks a position of a Reed Solomon symbol in the fade as an erasure and error correcting code (348) corrects errors in the Reed Solomon code word with the marked erasure.
