The Design Of Reusable Waveform Component In FPGA Based On OCP

As the Software Communication Architecture(SCA) applying to high-speed and broadband Softeware Defined Radio(SDR) system,it can not satisfy with the requirement of processing only using GPP and DSP,and FPGA is increasedly used in SDR platform based on SCA.CORBA is used by SCA as the message passing technique for the communication between waveform components.However,offering support for CORBA can be difficult and impractical to achieve within FPGAs. Therefor,researching on the technique by which the interfaces of SCA waveform component are designed in FPGA has great significance for practical application of SCA in SDR.CP289 aims to standardize the way in which components communicate with their external environment,and provides a mechanism by which SHPs,such as DSPs and FPGAs,can be integrated into the SCA.The paper aims to implement the reusability of the waveform component in FPGA, in-deepth studies the principles that the CP289 is built on to extend the SHP waveform component reusability and portability,focuses to analyse the Open Core Protocol and researches on the key technique by which the interfaces of SCA waveform component are designed in FPGA based on OCP.According to the CP289,the paper designes and implementes the OCP interfaces for the SCA components and container in FPGA, simulates the function of the system,and tests the reuseability of the wavform components.
