In the original Freight Train of Pixels post, I laid out three main technical challenges to building a continuous recording 3.8Gpx/s imager. All three have now been dealt with, using a Zynq Ultrascale+ SoC as a hardware base. The detailed implementations for each one has its own post:
[The Source] – Full-speed read-in of the CMV12000’s 64 LVDS channels.
[The Pipe] – Hardware wavelet compression engine.
[The Sink] – Sustained 1GB/s writing to an NVMe SSD.
Now it’s time to put all three pieces together and run it as a full pipeline.
The first thing to point out is that this is 12000 frames of continuously-recorded 4K 400fps video. That’s 30s in real-time and 500s of playback at 24fps, something very few existing high-speed imaging systems can do. And I can keep going. This clip is “only” 24GB of a 1TB SSD. To fill the entire 1TB would take about 20 minutes at this bit rate. That’s 20 minutes of real-time, 5.5 hours of playback at 24fps.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
