EdgeCortix SAKURA-II Edge AI accelerator with 60 TOPS and only 8W

edgecortix-sakura-ii AI

EdgeCortix introduces SAKURA-II, an AI accelerator for the Edge with impressive performance of 60 TOPS (INT8) and a low power consumption of 8 watts. The chip is designed for complex AI tasks, such as processing large language models (LLM), large vision models (LVM), and transformer-based multimodal applications, as well as for applications at the network edge, such as devices IoT and autonomous vehicles.

It allows flexibility in terms of hardware, with the possibility of integrating it into both PCIe expansion cards with one or two SAKURA-II chips, or also in M.2 2280 modules (PCIe x8 or x16 interface) If you prefer. Therefore, powers of up to 120 TOPS can be reached with INT8 or 60 TFLOPS with BF16.

The AI ​​platform also offers a part of cutting-edge software, with a MERA suite for programming and optimization, a heterogeneous compilation platform, advanced quantification techniques, and model calibration capabilities. It also features integration with popular development frameworks such as PyTorch, TensorFlow Lite, and ONNX, as well as access to an extensive library of cutting-edge transformative models and convolutional models.

In addition, the company EdgeCortix has also thought about taking its AI accelerator designs further, being able be integrated into SoCs from other companies, such as AMD.
