With the USB 3.0 plugin module, any computer with USB 3.0 connectivity can be used as an AXIOM Recorder. This allows for defining format/container/metadata/etc. of uncompressed raw 4k footage.

One AXIOM Beta USB 3.0 plugin module provides users with around 400MB/S bandwidth (3.2Gbit/s) and, in theory, this can be doubled by utilising two of the AXIOM Beta's module slots.

1 Development Notes

Development Status: PCB has been populated. Software in development.

The USB3 interface chip is an FTDI FT601 (https://www.ftdichip.com/Products/ICs/FT600.html) and acts as a multi channel 32-bit FIFO interface.

FTDI works out of the box and can be programmed/configured via USB if necessary.

The Lattice MachXO FPGA needs to be programmed through the Beta - the JTAG interface (as well as control signals) of the Lattice MachXO FPGA on the USB3 plugin are connected to the IO pins of the plugin module slot. A little trick is required for utilizing this:

  1. A special MachXO2 bitstream is loaded which basically passes through a bunch of signals between the Plugin IO pins and the PIC microcontroller
  2. A special PIC firmware is used which does basically the same as the original one, but with slightly different pins (i.e. those connected to MachXO GPIOs not the JTAG interface). This way the normal scripts (pic_jtag_* scripts) which usually program the MachXO2 on the camera's Main Board, now generate signals which get relayed to the plugin IOs.
