Abstract: Hardware accelerators for accelerated grouped convolution operations. A first buffer of a hardware accelerator may receive a first row of an input feature map (IFM) from a memory. A first group comprising a plurality of tiles may receive a first row of the IFM. A plurality of processing elements of the first group may compute a portion of a first row of an output feature map (OFM) based on the first row of the IFM and a kernel. A second buffer of the accelerator may receive a third row of the IFM from the memory. A second group comprising a plurality of tiles may receive the third row of the IFM. A plurality of processing elements of the second group may compute a portion of a third row of the OFM based on the third row of the IFM and the kernel as part of a grouped convolution operation.

Abstract: Embodiments described herein provide a processing apparatus comprising compute circuitry to generate neural network data for a convolutional neural network (CNN) and write the neural network data to a memory buffer. The compute circuitry additionally includes a direct memory access (DMA) controller including a hardware codec having encode circuitry and a decode circuitry. The DMA controller reads the neural network data from the memory buffer, encode the neural network data via the encode circuit, writes encoded neural network data to a memory device coupled with the processing apparatus, writes metadata for the encoded neural network data to the memory device coupled with the processing apparatus, and decodes encoded neural network data via the decode circuit in response to a request from the compute circuitry.

Abstract: A mechanism is described for facilitating efficient memory layout for enabling smart data compression in machine learning environments. A method of embodiments, as described herein, includes facilitating dividing an initial tile representing an image into primary multiple tiles such that each tile of the primary multiple tiles is regarded as an independent image as processed by one or more processors of a computing device. The method may further include computing the primary multiple tiles into secondary multiple tiles compatible in size of a local buffer. The method may further include merging the multiple secondary multiple tiles into a final tile representing the image, and compressing the final tile.
