ZHANG Sheng, ZHANG Guo-yong, YAN Ao. SOPC design of sensor node based on open source processor[J]. 2016, 35(3): 111-114. DOI: 10.13873/J.1000-9787(2016)03-0111-04.
System on programmable chip( SOPC) of sensor node for wireless HART network is designed based on open source microprocessor OpenRISC1200
which adopts the method of hardware / software co-design. It can implement basic function of node task processing and others. The whole hardware system is simulated firstly. Then use ISE tools to synthesize it and evaluate the overall performance
at last download to FPGA for software development and validation. For practical applications
real-time operating system RAW-OS and wireless HART protocol are ported
and programs are compiled to complete the test
the result shows that the desiged node system on chip( SOC) is stable and reliable in function.
