AI ACCELERATOR

Dedicated Artificial Intelligence (AI) IP: ‘GPT’ AI Accelerator

​

The configurable ‘GPT’ AI accelerator is designed for Convolutional Neural Network (CNN) inference. The highly-optimized design provides for convolution, pooling, dropout, padding, and programmable activation functions. Running at up to 1GHz in 28nm technology, the design contains building blocks of 288 MAC units, scalable to beyond 2,000 MACs. Performance, power, and accuracy can be optimized using built-in integer or 16-bit floating point operations. GPT provides a library of popular CNN networks; support for frameworks such as Tensorflow and Caffe is in development.
