This paper addresses the design of systolic array (SA) based convolutional neural network (CNN) accelerators for mobile and embedded domains. On- and off-chip memory accesses to the large activation inputs (sometimes called feature maps) of CNN layers contribute significantly to total energy consumption for such accelerators; while prior has proposed off-chip compression, activations are still stored on-chip in uncompressed form, requiring either large on-chip activation buffers or slow and energy-hungry off-chip accesses. In this paper, we propose CompAct, a new architecture that enables on-chip compression of activations for SA based CNN accelerators. CompAct is built around several key ideas. First, CompAct identifies an SA schedule that has nearly regular access patterns, enabling the use of a modified run-length coding scheme (RLC). Second, CompAct improves compression ratio of the RLC scheme using Sparse-RLC in later CNN layers and Lossy-RLC in earlier layers. Finally, CompAct proposes look-ahead snoozing that operates synergistically with RLC to reduce the leakage energy of activation buffers. Based on detailed synthesis results, we show that CompAct enables up to 62% reduction in activation buffer energy, and 34% reduction in total chip energy. [ABSTRACT FROM AUTHOR]

Managers, executives and professionals spend immeasurable hours on their learning, networking, meetings, delivering presentations, writing articles/papers, getting qualifications, and attending lectures, workshops and classes for training and developing themselves just to stay competitive in this fast growing world. But a significant number of them overlook their own professional image; they need to pay attention to this aspect of professionalism, as it adds to their demeanor and success. The way we dress at workplace has an incredible influence on the way others perceive us. Thus, careful consideration should be paid to the dress code and style as it enhances the business performance strategy. The matter of fact is that significant contributions towards business contentment can be visually seen through dress code. Hence, the paper focuses on examining the impact of dressing on the performance of an employee and also the level of awareness of dress code amongst people, further highlighting the right dress code using a broader range of styles.
