Embodiment Construction

[0053] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0054] This embodiment mainly involves the following aspects:

[0055] 1. Platform design: The SCA-based software radio platform includes a variety of processing devices, and the dynamic reconstruction of the waveform component FPGA requires the design of the main control CPU, general interconnection network, loading agent FPGA, DDR, and FLASH. The master CPU manages all resources, including FPGA component reconfiguration management functions. The general interconnection network realizes the intercommunication between various computing resources and the intercommunication with the main control CPU. The Load Agent FPGA is responsible for configuring the Waveform Component FPGA. DDR and FLASH are used as auxiliary storage devices for loading agent FPGA, such as figure 1 shown.

[0056] 2. Data channel design: the main control CPU to the load...

Abstract

The invention discloses a software radio platform based on SCA, which includes a main control CPU, a loading agent FPGA, DDR, FLASH and a waveform component FPGA, and the loading agent FPGA includes the following program modules: SRIO_Driver module, HAL_LD-PD module, HAL_LD-PD module APP module, MAIN_CTRL module, FLASH_CTRL module, DDR_CTRL module, K7_CFG module. The loading agent FPGA is responsible for configuring the waveform component FPGA, which effectively solves the problems of IO / component / link adaptation difficulties and easy failure of reconfiguration caused by general FPGA dynamic reconfiguration.

Description

technical field [0001] The present invention designs a kind of software communication architecture (Software Communications Architecture, SCA)-oriented waveform component FPGA reconfiguration method, particularly relates to a kind of in SCA system, waveform component FPGA is automatically reconstructed into new logic, new function on demand, and A method that does not require any equipment outside the system. Background technique [0002] The Software Communication Architecture (SCA) was proposed by the US military's Joint Tactical Radio System (JTRS), which provides an effective reference specification for the development of software-based multi-mode communication terminals. Specific radio functions exist in the form of waveform components, are managed uniformly by the operating system, and are configured according to application requirements. This method provides good support for the synthesis, management, and free configuration of radio functions. [0003] Since the oper...
