FPGA-based realization of multi-sensor access

With the development of communication technology and computer network, data collection and processing have become an important part of data communications, which are widely used in digital communication and control. Traditional data collection and processing uses a microcontroller or DSP as the CPU to make sure the implementation. In this way, the data processing is limited by machine cycles and processing speed, which cannot meet the requirements of real time and synchronization For that reason we propose the attempt of multi-sensor access by using FPGA that can be reset and is full of system building flexibility. Our research is based on XILINX´s Spartan3A-DSP-1800´s FPGA development board and adopts modular design that lets different IP cores assigned to crossover module, temperature and humidity sensor module, counter module, pressure sensor module and communication module respectively to implement the construction of system on chip, improve the system´s flexibility and stability and greatly simplify the circuit.
