A custom hardware module that interfaces bridge between Mother Board and both mass storage devices such as SATA 2.0 HDD and USB 2.0 storage Devices that can fit in 5-1/4” bay in COTS. This included hardware, firmware, device driver software, test software, simulation software along with enclosure. It has FPGA based custom Host and Device Interfaces interconnected as a bridge between PC’s mother board and HDD device, USB Device. It incorporates custom SATA-HOST, SATA-DEVICE IP cores in one FPGA for SATA interface and custom USB-HOST, USB-DEVICE IP cores in other FPGA for USB interface.

After user authentication, the system boots using an ARM Cortex A9 controller from an OTP, verifies the content of a NOR Flash holding the application code of the system and the bit stream of configuration files for SATA and USB FPGAs. Once verified, respective FPGAs are configured using SATA and USB bridges, COTS is released from power on reset to establish seamless communication with respective storage devices.
