摘要
为满足MIMU/GPS组合导航系统微型化、高精度的要求,以TI公司TMS320VC33型浮点DSP器件为CPU,Altera公司的Cyclone系列EP1C6Q240I7型号FPGA为外设扩展器件,设计了一种实时性好、精度高、体积小、外设配置灵活的组合导航计算机系统;采用浮点放大器和FPGA实现了MIMU的高速、高精度数据采集;采用单片机控制接收、判断和校验GPS-OEM板异步串口输出的报文;各处理器之间通过双端口RAM共享数据,从而实现了分布式控制。
In order to meet the requirements of MIMU/GPS integrated navigation system, which are mini-size, high precision, an embedded navigation computer system is designed, in which the CPU is high speed and float type DSP chip TMS320VC33 produced by TI, the peripheral device expansion is implemented by FPGA chip EP1C6Q24017 produced by Alters. The system has the characteristics of good real time, high precision, small size, peripheral device modified easily. Using float-point amplifier and Field--Programmable Gate Array （FPGA）, sampling the data of MIMU in high speed and high accuracy has been realized. Single chip miero-eomputer has been used to receive, judge and verify the GPS message and they can be sent to the dual port RAM to be share, which leads to the realization of distributed control of the system.
