Abstract: A DSP system, capturing the data from a main bus via a bus operating at the clock speed of a first frequency, and sending the data to a DSP unit reading the data at the clock speed of a second frequency, the DSP system comprising: a bus control unit, which is adapted to transfer data from the main bus to the bus; a pulse wave generator, producing a pulse wave that synchronous to the bus, the pulse wave is comprised of sequential time slots, wherein a part of the time slots are DRQ slots that respectively comprises a data requesting signal, and the other times slots are normal slots; and an interface unit, capturing the data from the bus control unit via the bus according to the data requesting signal, and transmitting the data to the DSP unit. According to the DSP system of the present invention, the FIFO register that used in the prior art could be abandoned, whereby saving the occupied space of the whole system.

Abstract: An apparatus and method is provided for generating VBI data coding waveforms. The present invention utilizes a single look-up table that stores sampled values of sine waves in direct waveform synthesis for both color burst processing and VBI data coding processing. Furthermore, the present invention utilizes a 2T pulse as a signalling waveform in direct synthesis to overcome the problem of overlap for conventional unit pulse durations.

Abstract: A method and apparatus for noise burst detection in a signal processor is provided. The method and apparatus is based on the zero-crossing rate (ZCR) of the received signal, which is defined as the number of times the magnitude of the received signal becomes zero during a specific counting period, to determine whether the received signal is a noise or a normal signal. The received signal is sampled at a specified sampling rate. Whether the signal waveform undergoes a zero-crossing is determined by comparing the polarity of the current sampled magnitude with that of the previous one. If the polarities are different, it indicates that the signal waveform has undergone a zero-crossing during the current sampling period; otherwise, it indicates that the signal waveform has not undergone a zero-crossing. The count of zero-crossing during each counting period is compared with a preset threshold value.
