一种基于SCA的FPGA硬件抽象层设计方法

Hardware Abstract layer design of FPGA based on SCA

针对软件无线电关于波形软件的可移植性要求,借鉴软件通信体系硬件抽象层连接规范,采用开放式体系结构和模块化设计思想,研究了一种针对FPGA的硬件抽象层设计与实现方法。通过引入source和sink接口抽象底层的硬件连接,使FPGA的波形设计与具体硬件平台分离,实现硬件系统中波形软件的动态配置。在实际信号处理系统中的应用表明,使用该方法设计的软件具有很好的可移植性、可重用性和可互操作性,可减少重复开发,能有效缩短系统开发周期,提高系统开发效率。

According to the portability requirement of waveform component,the specifications of hardware Abstract layer connecting in the system of software communications architecture（SCA）,and the open architecture and module design idea,a method of hardware Abstract layer（HAL） on FPGA was dealt with.This paper referred to how to separate the FPGA waveform design from the lower layer characteristic of the hardware and dynamical deploy waveform component on hardware system by introducing source and sink interface.In fact,the software based on this method can easily apply their codes to other platform,and greatly decrease the systemic cycle of design,and improve its efficiency.
