Coral Accelerator Module
from Google
Murata and Google develop the world's smallest AI module

Overview

Accelerating the algorithms essential to AI

Google

Google combined Murata’s compact package technology and Google’s own Edge TPU chip enabling power-efficient and high-performance machine learning inference to create a new compact AI module.
Enclosing Google’s Edge TPU ASIC in a package with a smaller footprint simplifies the design of the printed circuit board.

Strengths

  • Supports operation at up to 4 TOPS (trillion operations per second).
  • Boosts power efficiency by ensuring power consumption of only 0.5 W per 1 TOPS.
  • Supports PCIe Gen 2 and USB 2.0 interfaces.

The Accelerator Module is a multi-chip module (MCM) integrating the Edge TPU and exclusive power control technology. Compactness is key to achieving extremely robust functionality in devices with limited space, because it is essential to optimize use of all space on circuit boards.

Designed by Google, the Edge TPU is a compact ASIC that speeds up model estimation times while using very little power. Murata’s compact package technology and power supply design (noise suppression) make it possible to achieve a high-performance, compact product that takes up very little space.

Model estimation time comparison

When implemented on the latest embedded CPU or the Coral Dev Board, a comparison of model estimation times using TensorFlow Lite format shows that inference time is substantially reduced and confirms that genuinely high performance can be achieved.
