Abstract: A system and method for scalable video coding that includes base layer having lower resolution encoding, enhanced layer having higher resolution encoding and the data transferring between two layers. The system and method provides several methods to reduce bandwidth of inter-layer transfers while at the same time reducing memory requirements. Due to less memory access, the system clock frequency can be lowered so that system power consumption is lowered as well. The system avoids having prediction data from base layer to enhanced layer to be up-sampled for matching resolution in the enhanced layer as transferring up-sampled data can impose a big burden on memory bandwidth.

Abstract translation: 一种用于可缩放视频编码的系统和方法，包括具有较低分辨率编码的基本层，具有较高分辨率编码的增强层和两层之间的数据传输。 该系统和方法提供了几种减少层间传输带宽的方法，同时减少了内存需求。 由于更少的存储器访问，系统时钟频率可以降低，从而也降低系统功耗。 该系统避免了从基础层到增强层的预测数据被上采样，以在增强层中匹配分辨率，因为传送上采样数据可能对存储器带宽造成很大的负担。

Abstract: Systems, apparatuses, and methods for converting data to a tiling format when implementing convolutional neural networks are disclosed. A system includes at least a memory, a cache, a processor, and a plurality of compute units. The memory stores a first buffer and a second buffer in a linear format, where the first buffer stores convolutional filter data and the second buffer stores image data. The processor converts the first and second buffers from the linear format to third and fourth buffers, respectively, in a tiling format. The plurality of compute units load the tiling-formatted data from the third and fourth buffers in memory to the cache and then perform a convolutional filter operation on the tiling-formatted data. The system generates a classification of a first dataset based on a result of the convolutional filter operation.
