Burst memory transfer from a memory to a microprocessor (CPU) is accomplished using analysis including determining first and second conditions. If an output enable is consecutively activated for more than one consecutive system clock cycle, following the address phase, the memory will initiate a burst transfer sequence. The addresses of subsequent data bytes or words following the first byte or word are determined by the memory advancing or incrementing its internal address counter until the burst transfer has been suspended or terminated. If the output enable pin is deactivated prior to the next address phase requested by the CPU, burst transfer will be suspended until the output enable pin is activated again. If the CPU requests the next address phase (chip enable activated) from the memory while the output enable is activated, the burst in progress will be terminated.

A spark knock detection system is disclosed which has a vibration detector connected in proximity to the engine for converting a vibration into an electrical output signal representative of the vibration. A sampler which is connected to the vibration detector samples the electrical output signal and converts the electrical output signal into a numerical data pattern corresponding to the electrical output signal. A feature extractor which is connected to the sampler converts the numerical data pattern into frequency domain signal portions which have a magnitude. A classifier which is connected to the feature extractor receives the frequency domain signal portions. The classifier has predetermined coefficients for classifying the frequency domain signal portions to indicate the presence of spark knock.
