Using Altera’s Quartus Ⅱ,Nios Ⅱ IDE and Sopc Builder development tools,the proton precession magne-tometer principle host hardware platform is designed in a cyclone Ⅱ series FPGA chip(EP2C35).The proton precession magnetometer principle host core circuit’s single-chip system-logic design is achieved by building and configuring the Nios Ⅱ soft-core processor,developing the IO interface and sensor control circuits,programming some hardware units’ VHDL code,for example the equal precision cymometer and the DPLL.Through researching the embedded operating system con-figuration technology and building the NIOS Ⅱ soft-core processor’s μClinux cross-compile environment,the μClinux sys-tem is transplanted to the NIOS Ⅱ environment.Another important task is writing the device drivers’ and user programs’ code.Through these work,the design realize the host function and achieve the expected target.
