SYSTEM AND METHOD FOR PROVIDING DIAGNOSTIC INFORMATION

摘要

A data processing system has a system bus, an analog-to-digital converter (ADC), a signal processor, a memory, compression and packing units, and a debug unit. The ADC samples a baseband signal, and provides a digitized signal representative of the baseband signal the system bus. The signal processing block converts the digitized signal to a processed signal in the frequency domain. The memory is coupled to the system bus and is for storing the processed signal. The compression unit is coupled to the system bus and is for capturing the processed signal and compressing the processed signal to produce a compressed signal. The packing unit is coupled to the compression unit and is for packing the compressed signal to produce a packed signal. The debug unit is coupled to the packing unit and is for converting the compressed and packed signal to a diagnostic message. The disclosed data processing system and method provides diagnostic messages in near real-time.

1. A method for providing diagnostic information in a data processing system, the method comprising:
sampling baseband signals in time domain; converting the baseband signals to digitized signals; storing the digitized signals in a system memory; converting the digitized signals to processed signals in frequency domain; compressing the processed signals to generate compressed signals; packing the compressed signals to generate packed signals; and generating a diagnostic message from the packed signals.
