Development of Asynchronous Data Processing System by using General-purpose Microprocessors
Development of asynchronous data processing system is usually based on dedicated asynchronous elements. Advanced generalpurpose microprocessors have a set of features facilitating development of asynchronous data processing system. Such a system is designed for non-stationary signals using non-conventional digital signal processing methods. Implementation of the principles of the data level-crossing sampling, switching system to power reduction modes and asynchronous interaction between system units is determining asynchronous nature of the system. Paper represents architecture of the system implemented on Philips P89PLC936 microcontroller using a principle of the level-crossing sampling. The system is able to process input signal with maximum frequency fmax = 2kHz using sampling level number N = 7. Ill. 3, bibl. 10 (in English, summaries in English, Russian and Lithuanian).
