Soon launching via the Crowd Supply website is the Vision FPGA SoM development board, offering an FPGA-based SoM with integrated vision, audio, and motion-sensing capability. The Vision FPGA SoM measures just 3 cm x 2 cm and is an iCE40 5K FPGA based System on Module that integrates a low power qVGA vision sensor, 3 axis accelerometer/Gyroscope and an I2S MEMS microphone in a small form factor. The board has been developed with the following in mind say it’s creators.
– Low Power Image Sensor + FPGA: Overall power consumption will be minimized and in the 10-20mW range to enable battery powered applications.
– Well-designed Host Interface: Easy to integrate into a larger system using an interrupt driven SPI host interface, programmable IO voltages to support a glueless HW interface.
– Modular Design: Complexity will be localized to the SoM so that the developer can quickly integrate this device into their system using a breadboard as well as a simple API. All required components for vision/audio/motion (eg. image sensor and illumination) will be integrated so the developer doesn’t have to cobble together parts. The solution will translate into a final product with minimal changes.
– Flexible and Easy to Use: The Vision FPGA SoM is made to be easy to integrate mechanically and electrically. The SoM will appear like an SPI device with a SW library to support it. You will have the ability to configure the FPGA CRAM instead of having to program the Flash followed by a reset to configure the FPGA. Provide flexibility to the developer in choosing an image sensor while providing a reasonable low-cost default option.
– Strong set of features: Will not be just another FPGA board clone. Require a reasonably sized SRAM to allow for temporary data storage at low power (not DRAM!) which is especially important for vision applications where multiple image frames may need to be captured/processed. Audio and IMU are commonly used together with vision and will make sense to integrate on this platform.
– Documented and Open FPGA code: Ideally use an open source toolchain. Well-documented code and plenty of simple examples for each subsystem as well as a large design that ties together various parts of the SoM.

Potential applications for the small form factor Vision FPGA SoM board include :
– Image/Sound/Motion capture
– Trigger on scene change/sound/motion to capture video/audio
– Capture IMU readings with images for VR/AR applications
– Beamform audio with vision input to pay attention to areas with motion
– Low Power Edge Processing. Preserve privacy by processing data on the SoM
– Enable developers to detect objects, keywords and gestures using a low complexity Neural Network with no cloud connectivity required ie. tinyML
