The invention belongs to an
avionics system task
processing platform design and development technology, and relates to an
embedded software operating platform design method based on a DDS, and a
simulation platform. The
embedded software operating platform design method comprises the following steps: 1, DDS
middleware is deployed in a kernel of a VxWorks6.6
operating system; 2, the DDS is configured under the VxWorks6.6
system, and data reception and transmission are achieved through design; 3, a CPCI drive program is achieved under the VxWorks6.6
system, and thus the system can complete boardcard calling and data reading through a drive; 4, a CPCI
bus drive program is designed under an AcoreOS653
operating system, and board card calling and
data transmission are completed; and 5, a VxWorks6.6 board card and an AcoreOS653 system board card achieve two-way
data transmission through a CPCI board card. A flexible data distribution scheme is provided for an airborne embedded platform, andthe
embedded software operating platform design method can be suitable for design and development of an
avionics task system.
