基于硬件构件的虚拟仪器硬件及底层驱动设计

Design of Hardware and Driver of Virtual Instrument Platform based on Hardware-component

硬件构件是一种开发嵌入式硬件系统的新方法,它利用具有重用性的硬件功能模块,大大简化嵌入式系统的硬件开发过程,有效提高系统的稳定性。采用新兴的硬件构件思想设计实现了一种虚拟仪器硬件平台,包括功能模块、主控模块和通信模块,可实现示波器、波形发生器等功能。在底层驱动的设计中,提出了一种可应用在小型操作系统上的硬件抽象层设计方案,能"无缝"连接不同功能模块,实现了平台良好的扩展性和可移植性。

Hardware-component is a new method to develop hardware of embedded system by using hardware function modules, which can simplify the development process and enhancing the stability of system. A platform of virtual instrument is designed according the method, including function module, main control module and communication module. This platform can implement different virtual instruments： virtual oscillograph, virtual waveform and etc. Then constructing hardware abstract layer based on tiny OS is proposed in the development of driver program,which can connect different modules smoothly.
