Field programmable gate array (FPGA)-based common object request broker architecture (CORBA) communication device

Abstract

The invention provides a field programmable gate array (FPGA)-based common object request broker architecture (CORBA) communication device, which comprises a master resolution module, a master packaging module, an interconnect module, a plurality of resolution sub-modules and a plurality of packaging sub-modules, wherein each resolution sub-module and each packaging sub-module correspond to each application module on an FPGA; the master resolution module performs data information exchange with other processors by external data interfaces, and transmits data information to the application modules by the interconnect module and the resolution sub-modules; and each application module transmits the data information to the master packaging module by corresponding packaging sub-modules and the interconnect module. The FPGA-based CORBA communication device is designed, implemented and run on the FPGA, is free from the limitations of the specific type of the FPGA, and can realize direct CORBAcommunication between the application modules on the FPGA and the application modules on the other processors without running any adaptor module and agent module on a general purpose processor.

Description

Technical field [0001] The present invention relates to the field of computer communication, and in particular to a communication device designed and implemented on an FPGA (Field Programmable Gate Array) in an application system containing a variety of processors, which can enable a communication device running on the FPGA The application module directly communicates with the application modules running on other processors with CORBA (Common Object Request Broker Architecture, Common Object Request Broker Architecture). Background technique [0002] With the rapid development of application technologies such as mobile communications, navigation and positioning, remote sensing and remote sensing, it is increasingly necessary to rely on multi-processor application systems composed of FPGAs and general-purpose processors to complete various complex tasks in these fields. In multi-processor application systems, FPGAs usually run application modules with simple logic and huge calcula...

Problems solved by technology

[0006] 1. Each function call request between the application module on the general processor and the application module on the FPGA must go through up to 6 times of data processing before it can be completed. If the function call request needs to return the function call result, it also needs to go through It takes 6 times of data processing to complete, which increases the operation delay and reduces the communication efficiency

[0007] 2. Since an adapter module and several agent modules corresponding to each application module on the FPGA must be run on the general processor, thus increasing the workload of the general processor, and the more the number of application modules on the FPGA, The general-purpose processor will be more loaded

[0008] 3. Since the message format actually transmitted between the general-purpose processor and the FPGA is user-defined and non-standard, different manufacturers will define different message formats, which leads to general-purpose processors developed by different manufacturers The adapter module cannot interoperate with the FPGA adapter module and the FPGA application module, and cannot really take advantage of the good interoperability of CORBA
