Command Set of Real-Time Micro-Measurement System and Its Analyzing Algorithm
To minimize the interference in the long-range transmission of small signal, we propose a new design scheme of an embedded micro-measurement system where the digital measurement part is close to the output of the converter. It use dual-core hardware system with Field-Programmable Gate Array (FPGA) and Advanced RISC Machines (ARM) and program-controlled command set based on real-time operating system in software. FPGA takes charge of synchronous sampling in the system for its real-time performance, while ARM could be used to analyze the command and send reply since it is more flexible and easily to be controlled in transactional issues. This command set is referred to the command syntax of oscilloscope, based on the real-time operating system and the properties of ARM as well. Meanwhile, it has the open part to develop in the future, which make the system more flexible and expandable.
