HIGH-SPEED REAL-TIME MONITORING DEVICE FOR EMBEDDED SYSTEMS

摘要

The invention of high-speed synchronous digital electronic data communication method and target embedded systems using differential signal transmission method to debug the circuit and the CPU firmware to the operating state of the high-speed real-time or on a high-speed real-time monitoring device of an embedded system that can be monitored in real time, which synchronous data communication method of the digital clock signal and digital data signal and a differential signal driver actuation signal generating the other hand, the monitoring data packets sent to receive MCU / DSP input a start signal, a digital clock signal and a first differential signal to the differential signal driver for substitution, the second differential signal driver to replace the digital data signal to the differential signal with , packet data transmission begins monitoring the inverse differential signal substitution third target embedded system consisting of a differential signal receiver and a digital clock a differential signal from the first differential signal receiver station to replace, the second differential of the inverse substitution digital data differential signal and a signal receiver, and a real-time monitoring equipment consisting of a third differential signal driver to replace the monitoring data packet transmission start signal to the differential signal, the first covering wire pairs connecting the first differential signal and a first actuator and a differential signal receiver, the second differential signal driver and the second covering wire pairs connecting the second differential signal receiver and the third coated wire pair and connecting the third differential signal to the actuator and the third differential signal receiver, the logic of the target embedded systems and real-time monitoring equipment The ground features composed of a transmission line consisting of interconnected logic ground line.
