Description

technical field [0001] The invention relates to an evaluation system and method, in particular to an evaluation system and method for an embedded sensor network terminal. Background technique [0002] Sensor network technology is an important technology in the field of information technology applications. At present, for different sensor systems, it is generally necessary to design corresponding development systems, especially to develop various hardware architectures of sensor networks. This kind of development requires the design of a dedicated processor system and sensor interface circuit. Usually, the debugging and testing of the sensor network can only be implemented after the completion of the hardware system. The advantage of this method is that it is targeted, but its disadvantage is that it cannot evaluate the designed system before the hardware is manufactured. Therefore, it is impossible to demonstrate whether the design structure meets the requirements of the de...
