hxGPT SONG AI Cores: Scalable Deep Neural Network AI Accelerators for Handsets and Edge Processing

THIS POST WAS ORIGINALLY PUBLISHED ON THIS SITE Click Here To Read Entire Article

LAS VEGAS, Jan. 12, 2018 /PRNewswire/ — Consumer Electronics Show — Today Hua Xia GPT (hxGPT), China’s leading licensor of customizable processor IP cores, announced a scalable, programmable AI accelerator family available for licensing at CES 2018. Solutions scaling from handset to edge processing support a wide range of applications including the Internet of Things (IoT), Advanced Driver Assistance Systems (ADAS), Self-driving Cars, Robotics, Surveillance, and Machine Vision.

The “Song” AI core is a highly configurable IP block that provides for efficient implementations of CNN’s. Running at up to 1GHz in 28nm technology, each accelerator core contains 288 MAC units scalable to beyond 2 TFLOPS. Performance, power, and size can be optimized efficiently supporting both low power embedded IoT devices, handsets, and edge processing designs. Accuracy can be optimized using built-in 16-bit integer or floating point operations. Support for compressed 8-bit data is provided. Extended precision intermediate results reduce errors in both regression and classification workloads.

Targeting inference applications, the AI accelerator supports multi-dimensional tensor processing. The highly optimized design provides direct support for convolution, pooling, dropout, padding, and programmable activation functions.  A library of popular CNN networks is provided with generalized framework support (e.g. Tensorflow, Caffee, etc.) in development.

Previously hxGPT announced availability and licensing of the Changcheng out-of-order superscalar CPU. Validated in TSMC’s 28nm process, the core is configurable providing for multiple performance levels based on customer requirements. Memories, caches, and out-of-order features (issue window, ROB, rename, etc.) can all be customized. Depending upon technology selection the core can run up to 3GHz at very low power.

Building on hxGPT’s expertise in heterogeneous computing, the Song AI core easily integrates with hxGPT’s Changcheng CPU for ease of programming. Both are programmed using the same familiar processor programming environment.

WuxiDSP, hxGPT’s customer of both the Changcheng core and Song AI core noted “hxGPT’s cores are highly optimized and power efficient. Our first silicon using both of these cores is scheduled to sample later this year targeting edge IoT processing,” said Xiaodong Zhang, Chief Engineer of WuxiDSP.
