Automatic control system module
 The module is designed for reception, analysis and control of incoming data from various user transducers - up to 300 (weight, temperature, humidity, intensity of illumination, vibration, angularity, magnetic field and etc.).
Memec (Avnet) debugging boards, user-defined daughterboard with DAC/ADC devices were applied for the controller implementation. The system includes the Microblaze soft-processor core. It exchanges data via BRAM with four Picoblaze cores which preprocessing data from the appropriate sensors.
Hardware IP cores are realized as well as embedded ucLinux Web-server with direct access through CGI interface to configuration parameters of the sensors.
