Abstract


The rapid development of wireless sensor network (WSN) , general-purpose microprocessor and microcontroller can no longer meet the requirements of the wireless sensor network node controller chips, low power and low cost . In order to master the core technology of wireless sensor networks , the establishment of a sensor network hardware and software platform with independent intellectual property rights , and to promote the development of wireless sensor network technology . An urgent need to develop a microprocessor for wireless sensor network applications . The papers on the basis of the study of embedded microprocessor architecture , reference the EM78815 instruction system , designed a 8 dedicated RISC-based microprocessor . The design uses a line of advanced technology , the read and write bus separation of the Harvard bus technology , the advance control technology and advanced interrupt system . Functional testing of the microprocessor and the FPGA board . Finally, the SMIC 180 -nm process flow sheet . The papers in-depth study to achieve low-power low-cost microprocessors for wireless sensor network applications . Using Verilog HDL top-down forward design methods , complete MCU system design and test bench code synthesizable RTL code to write . From the system specification and design of various functional modules integrated into the circuit , and all aspects of the study design low -power low - cost design methodology . The experiments show that the successful implementation of the data acquisition node wireless sensor network node algorithms and data aggregation node algorithm based on the processor to build the hardware platform of wireless sensor network node . A center, self-organizing , multi-hop routing and dynamic topology wireless sensor networks .
