A SoC design approach is implemented for the MERGE project which features Machine Learning (ML) interface for the hardware design. This setup deals with
detection and localization of impact on a piezo metal composite. Development of the project is executed on Digilent ZYBO board. ZYBO incorporates Xilinx ZYNQ architecture. This architecture provides Processing System (PS) and Programmable Logic (PL) that communicate with each other via AMBA Standard AXI4 Interface.
Communication cost have major inuence on the system performance. A optimized hardware software partitioning solution will reduce the communication costs. Therefore, best fitting interface for the provided design is needed to be evaluated to trade-off between cost and performance. High performance of AXI Interface will provide efficient localization of impact, especially for real-time scenario. In the thesis, the performance of three different AXI4 interface are evaluated. Evaluation is performed on the basis of the amount of data transferred and the time taken to process it. Evaluation of interfaces are done through implementation of test cases in Xilinx SDK. Hardware design for AXI4-Interfaces is implemented in Vivado and later tested on Digilent ZYBO board. To test the performance of interfaces, read and write operations are initiated by PS on interface design. Each operation is performed for multiple data lengths. Average execution time is calculated that highlights time taken to transfer the corresponding input data length. Through these tests, it is found that AXI4-Stream is the best choice for a continuous set of data. Preferably, it provides unlimited burst length which is useful for the current project. Among other two interfaces, AXI4-Full performed better in terms of execution time as compared to AXI4-Lite.
