Make a efinix fpga module === Artix 7's module XME0712
We can use XME0712 module to test the base board.
AI Control High Tension Scenario
In high tension scenario, people are affect by prior.
We can leverage AI.
For example in police work:
Video and Audio and Police Body/Brain status are feed to AI for analysis
All interaction are control by AI
AI told police what to say.
Prevent high tension escalation.

PSRAM
Pseudostatic RAM (PSRAM or PSDRAM) is dynamic RAM with built-in refresh and address-control circuitry to make it behave similarly to static RAM (SRAM). It combines the high density of DRAM with the ease of use of true SRAM. PSRAM is used in the Apple iPhone and other embedded systems such as XFlar Platform.[71]
Some DRAM components have a self-refresh mode. While this involves much of the same logic that is needed for pseudo-static operation, this mode is often equivalent to a standby mode. It is provided primarily to allow a system to suspend operation of its DRAM controller to save power without losing data stored in DRAM, rather than to allow operation without a separate DRAM controller as is in the case of mentioned PSRAMs.
An embedded variant of PSRAM was sold by MoSys under the name 1T-SRAM. It is a set of small DRAM banks with an SRAM cache in front to make it behave much like a true SRAM. It is used in Nintendo GameCube and Wii video game consoles.
Cypress Semiconductor's HyperRAM[72] is a type of PSRAM supporting a JEDEC-compliant 8-pin HyperBus[73] or Octal xSPI interface.

FT4233HPQ FT4232+PD
FT4233HPQ This Hi-Speed USB device with Type-C/PD 3.0 controller IC fully supports the latest USB Type-C and Power Delivery (PD) standards enabling support for power negotiation with the ability to sink or source current to a USB host device.
This has one Dual-role PD port (PD port 1) which also carries the USB data communication. This can switch between the roles of sinking power from the host to power the peripheral, and sourcing power to charge the host computer. A second included PD port (PD port 2) is a power sink and can be used to connect an external power source/charger. This can provide power to the peripheral board as well as charging the host via PD port 1.
This is a USB 2.0 Hi-Speed (480Mb/s) to UART IC. It has the capability of being configured in a variety of industry standard serial or parallel interfaces. This fast quad channel bridge chip features 4 UARTs. Two of these have an option to independently configure an MPSSE engine allowing to operate as two UART/Bit-Bang ports plus two MPSSE engines used to emulate JTAG, SPI, I2C, Bit-bang or other synchronous serial modes.
