Imagination Technologies has announced two neural network accelerator cores

IP licensor Imagination Technologies has announced two neural network accelerator cores; the first devices within the PowerVR Series2NX family that the company first disclosed in September 2017.

The AX2185 and AX2145 offer inferencing capability on mobile applications and support a high degree of flexibility in terms of data resolution across neural networks, one of the more notable features of the architecture.

The PowerVR 2NX  has been designed as a core for inferencing on a mobile SoC from the ground up. It is a scalable architecture that comes with up to 8 neural network compute engines. Each engine is capable of up to 128 16bit multiply accumulates per clock (MACs/clk) and 256 8bit MACs/clk, giving at the high end 1024 16bit and 2048 8bit MACs/clk.
