This reference design provides an example of how to implement a face/object tracking application based on the Lattice sensAI stack. It includes a SPI, DDR memory interface IP blocks, an image signal processing engine, 8 CNN acceleration engines and an overlay engine to indicate the face in the image.
The reference design is optimized for the ECP5-85K FPGA. While the FPGA logic will be loaded from the external flash memory, the weights and biases are loaded from a SD card, connected to SPI interface.
