One strength of VxWorks is that it provides a high degree of architectural and hardware independence for application code. This portability is due to VxWorks’s modular design, which isolates all hardware-specific functionality into a set of libraries called the Board Support Package (BSP). The BSP libraries provide an identical software interface to the hardware functions of all boards. They include facilities for hardware initialization, interrupt handling and generation, hardware clock and timer management, mapping of local and bus memory spaces, memory sizing, and so on. 文档下载:http://www.51mcu.net/upimg/soft/VxWorks-BSP.pdf |
