The energy and payload capacity of small UAVs impose constraints on the complexity and size of the neural network. While Model compression has the potential to optimize the trained neural network model for efficient deployment on em-bedded platforms, pruning a neural network for DRL is more difficult due to the slow convergence in the training before and after pruning. In this work, we focus on improving the speed of DRL training and pruning. New reward function and action exploration are first introduced, resulting in convergence speedup by 34.14%. The framework that integrates pruning and DRL training is then presented with an emphasize on how to reduce the training cost. The pruning does not only improve computational performance of inference, but also reduces the training effort with-out compromising the quality of the trajectory. Finally, experimental results are presented. We show that the integrated training and pruning framework reduces 67.16% of the weight and improves trajectory success rate by 1.7%. It achieves a 4.43x reduction of the floating-point operations for the inference, resulting a measured 41.85% run time reduction.","PeriodicalId":239260,"journal":{"name":"2022 27th Asia and South Pacific Design Automation Conference (ASP-DAC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128289584","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

HD computing first encodes all data points to high-dimensional vectors called hypervectors and then efficiently performs the classification task using a well-defined set of operations. Although HD computing achieved reasonable performances in several practical tasks, it comes with huge memory requirements since the data point should be stored in a very long vector having thousands of bits. To alleviate this problem, we propose a novel HD computing architecture, called DistriHD which enables HD computing to be trained and tested using binary hypervectors and achieves high accuracy in single-pass training mode with significantly low hardware resources. DistriHD encodes data points to distributed binary hypervectors and eliminates the expensive item memory in the encoder, which significantly reduces the required hardware cost for inference. Our evaluation also shows that our model can achieve a $27.6times$ reduction in memory cost without hurting the classification accuracy. The hardware implementation also demonstrates that DistriHD achieves over $9.9times$ and $28.8times$ reduction in area and power, respectively.","PeriodicalId":239260,"journal":{"name":"2022 27th Asia and South Pacific Design Automation Conference (ASP-DAC)","volume":"229 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123306219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To improve the routing quality, this paper presents a deep learning-based congestion estimation algorithm that applies the estimation to a global router. Unlike existing methods based on traditional compressed 2D features for model training and prediction, our algorithm extracts appropriate 3D features from the placed netlists. Furthermore, an improved RUDY (Rectangular Uniform wire DensitY) method is developed to estimate 3D routing demands. Besides, we develop a congestion estimator by employing a U-net model to generate a congestion heatmap, which is predicted before global routing and serves to guide the initial pattern routing of a global router to reduce unexpected overflows. Experimental results show that the Pearson Correlation Coefficient (PCC) between actual and our predicted congestion is high at about 0.848 on average, significantly higher than the counterpart by 21.14%. The results also show that our guided routing can reduce the respective routing overflows, wirelength, and via count by averagely 6.05%, 0.02%, and 1.18%, with only 24% runtime overheads, compared with the state-of-the-art CUGR global router that can balance routing quality and efficiency very well. In particular, our work provides a new generic machine learning model for not only routing congestion estimation demonstrated in this paper, but also general layout optimization problems.","PeriodicalId":239260,"journal":{"name":"2022 27th Asia and South Pacific Design Automation Conference (ASP-DAC)","volume":"257 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117354161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While analog in-memory computing is extremely energy-efficient, the low precision narrows the spectrum of viable applications. In contrast, digital in-memory computing has deterministic precision and can therefore be used to accelerate a broad range of high assurance applications. Unfortunately, the state-of-the-art digital in-memory computing paradigms rely on repeatedly switching the non-volatile memory devices using expensive WRITE operations. In this paper, we propose a framework called STREAM that performs READ-based in-memory computing for streaming-based data processing. The framework consists of a synthesis tool that decomposes high-level programs into in-memory compute kernels that are executed using non-volatile memory. The paper presents hardware/software co-design techniques to minimize the data movement between different nanoscale crossbars within the platform. The framework is evaluated using circuits from ISCAS85 benchmark suite and Suite-Sparse applications to scientific computing.

Glass-based EWOD chips with non-regular electrodes are proposed, which allow more reliable droplet operations and facilitating integration of optical sensors for many biochemical applications. Besides, non-regular electrode designs (e.g., interdigitated electrodes) are utilized in EWOD chips to precisely control droplet volume, and electrodes with a specific shape become necessary for certain applications. However, due to the technical barriers of fabricating multi-layer interconnection on the glass substrate (e.g., unreliable process and high cost), both control electrodes and wires are fabri-cated with a single-layer configuration, which poses significant challenges to pin selection for non-regular electrodes under the limited routing resource. In this paper, we propose a minimum cost flow-based routing algorithm called NR-Router that features efficient and robust routing for single-layer EWOD chips with non-regular electrodes, which overcomes the challenges mentioned above. NR- Router is the first algorithm that can accurately route in single-layer EWOD chips with non-regular electrodes to the best of our knowledge. We construct a minimum cost flow algorithm to generate optimal routing paths followed by a light-weight model to handle flow capacity. NR-Router achieves 100% routability while minimizing wirelength at shorter run time, and generates mask files feasible for manufacturing via adjustments of design parameters. Experimental results demonstrate the robustness and efficiency of our proposed algorithm.","PeriodicalId":239260,"journal":{"name":"2022 27th Asia and South Pacific Design Automation Conference (ASP-DAC)","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122965974","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, prior works of BNN do not simultaneously meet the criterion that 1) achieving similar accuracy w.r.t its full-precision counterpart; 2) fully binarized without full-precision operation; and 3) rapid BNN construction, which hampers its real-world deployment.
