This paper proposed a high-speed secure storage SoC(system of chip) chip to address the issues of limited performance and insufficient security in traditional SATA controller storage systems, which could achieve the protocol data exchange between PCIe and SATA, implement local data secure storage based on the SM4 algorithm. By constructing a reasonable data transmission path between on-chip PCIe and SATA, utilizing PCIe VIP and UVM to build a system application-level simulation verification platform, it designed SystemVerilog language testcases and C code firmware, and controlled verification automation ran with scripts. The results show that on-chip devices IP establish links and channel data transmission correctly with bandwidth of 472 MBps between PCIe and SATA, SM4 algorithm implement local storage data encryption and decryption correctly, bandwidth up to 1.33 Gbps. According to the experimental results, it can be concluded that the SoC chip architecture design for PCIe and SATA bridging conversion is feasible, achieving secure storage of local data, and laying an important foundation for further research on high-speed data conversion access and secure transmission storage.
