A system and method for communicating with a processing element in a CORBA (Common Object Request Broker Architecture) system does not use an ORB (object request broker) in the processing element. A CORBA location is assigned to the processing element with a host loader and stored in a memory in the processing element. Addresses of CORBA objects are acquired with the host loader and loaded in the memory. The processing element communicates with the CORBA objects using CORBA object addresses. The CORBA objects communicate with the processing element using the assigned CORBA location of the processing element. Data is loaded into the processing element with the host loader.

CORBA field programmable gate array/digital signal processor system

An improved architectural approach for implementation of a low power, scalable topology for a software defined radio (SDR). Low power processors and switching elements forming building blocks are employed in an embedded switched fabric architecture network having a repeating building block topology that advantageously employs wormhole routing and has self-healing, fail-safe properties. Differential signaling is used and data rates in excess of 250 Mbps are possible. In one embodiment a dual civilian and military channel SDR is disclosed; in other embodiments, a plurality of independent SDR channels, with or without encryption, are disclosed. A plurality of different topologies are disclosed including torodial topologies having a planar topology with orthogonal connections, a planar topology with orthogonal and diagonal connections, and a cube topology with both orthogonal and/or diagonal connections.
