Accelerator Module datasheet Version 1.4 Features G oogle Edge TPU ML accelerator 4 TOPS peak performance (int8) 2 TOPS per watt I ntegrated power management PCIe Gen2 x1 or USB 2.0 interface Surface-mounted (LGA) module S ize: 15.0 x 10.0 x 1.5 mm Weight: 0.67 g Operating temp: -40 to +85 C RoHS compliant Description T he Coral Accelerator Module is a multi-chip module (MCM) designed to perform high-speed inferencing for machine learning (ML) models. It includes the Edge TPU ML accelerator with integrated power control, and it can be connected over a PCIe Gen2 x1 or USB2 interface. The Edge TPU is a small ASIC designed by Google that accelerates TensorFlow Lite models in a power ecient m anner: it s capable of performing 4 trillion operations per second (4 TOPS), using 2 watts of powerthat s 2 TOPS per watt. For example, one Edge TPU can execute state-of-the-art mobile vision models such as MobileNet v2 at almost 400 frames per second. This on-device ML processing reduces latency, increases data privacy, and removes the need for a constant internet connection. Note: USB 3.0 is also available but requires special design considerations and supportfor details, contact Coral Sales .
