Next Generation Architecture for Heterogeneous Embedded Systems

摘要

The Software Communications Architecture (SCA), a mandatory specification for Software Radio implementations by the Joint Tactical Radio System (JTRS), defines a Common Object Request Broker Architecture (CORBA) based component model for building portable applications in a heterogeneous environment. The Object Management Group's (OMG) CORBA is an accepted architecture for distributed systems that recently added a component model to its suite of standards. The authors' effort in leveraging the strength of CORBA by reusing OMG standards within the SCA, and improving OMG standards to match JTRS expectations, yields synergies that will broaden the vision of SCA as well as easing implementations and improving scalability within the SCA framework. A case study shows seamless integration of FPGA components into an SCA application. The Streaming Component Environment (SCE), a Mercury product that provides this kind of flexibility within our current high-performance embedded systems, is being extended to comply with the OMG and SCA specifications.
