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.
