The Design And Implementation Of Hardware Abstract Layer Connectivity On DSP/FPGA Based On Software Communications Architecture

Specialized Hardware Supplement to the Software Communications Architecture (SCA) Specification has brought out the conception of Hardware Abstract Layer Connectivity (HAL-C). According to this conception, the waveform developers can implement the software components easily depending on the APIs provided by HAL-C, while the platform developers have the responsibilities of offering HAL-C APIs to the upper developers. In this way, the waveform developers can devote the implementation of the waveform functions, ignoring the details of the lower hardware platforms. The waveform components that depend on the HAL-C APIs have stronger porting abilities than the traditional ones. Furthermore, the programmable hardware resources can be dynamically loaded and reconfigured whenever needed.In this paper, the HAL-C conception is studied according to the project requirements, and describes the functions of the HAL-C in software waveform implementation. Then the issues implementing the HAL-C on the Specialized Hardware Processor are addressed, and the methods of managing the components on FPGA and DSP by Proxy Components with the Domain Descriptor File and the Configuration Table are brought out. In the end, the validity of the proposed methods is tested.
