Model-Based Design of A Real-time Context-Aware Speech Enhancement System on an FPGA-SoC
2020 20th International Symposium on Computer Architecture and Digital Systems (CADS)(2020)
摘要
Modern Implementation platforms are suitable for realizing complex adaptive systems that require the system to adjust its behavior to satisfy variable design goals. A prominent example is context-aware systems that are capable of automatically adapting their operations according to the dynamic system context. This work introduces a model-based design flow for a context-aware FPGA-SoC-based system in the speech enhancement domain. The proposed design flow implements the adaptive context-awareness by exploiting the runtime reconfiguration feature of the state-of-the-art FPGA-SoC devices. By employing the proposed design flow and architecture, a context-aware speech enhancement application can be implemented in such a way that it is able to change its own processing algorithm to meet runtime goals and can lead to the area reduction of the FPGA by using one hardware-accelerated algorithm at a time.
