Google is going to launch a new set of Coral Accelerator Hardware for the AI at the edge applications. Both are using Edge TPU Co-processor technology from Google.
Coral Accelerator module is chip scale miniature 15×10 mm SMT module with PCIe/USB 2.0 interface. On the other hand, the Dev Board mini is a full fledged Single board computer having MediaTek Quad core Processor with 8GB eMMC, 2GB RAM and other peripherals.
About Coral
Coral technology provides a complete platform for accelerating neural networks on embedded devices. At the heart of our accelerators is the Edge TPU co-processor. It’s a small-yet-mighty, low-power ASIC that provides high performance neutral net inference.
The onboard TPU Co-processor is capable of 4 trillion operations per second (TOPS), using 0.5 watts for each TOPS (2 TOPS per watt). For example, it can execute state-of-the-art mobile vision models such as MobileNet v2 at 400 FPS, in a very power efficient manner.
