A unique feature of these attacks is that they no longer require intrusion into the hardware and software components of the victim vehicle; rather, it is possible to subvert the application by providing wrong or misleading information. We consider the problem of making vehicular systems resilient against these threats. A promising approach is to adapt resiliency solutions based on anomaly detection through Machine Learning. We discuss challenges in making such an approach viable. In particular, we consider the problem of validating such resiliency architectures, the factors that make the problem challenging, and our approaches to address the challenges.","PeriodicalId":188228,"journal":{"name":"Proceedings of the Great Lakes Symposium on VLSI 2022","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122832238","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}

Random placement of pages in Phase Change Memory (PCM) with more write accesses incurs higher write latencies. So, migrating write intensive pages from PCM to DRAM helps to reduce execution time and memory response time for applications. Existing techniques mainly focus on selecting the page migration candidate and migrate it immediately when it becomes eligible. This direct migration approach can hamper the response time of regular memory accesses. So, in our paper, we identify migration candidates and in addition, schedule when they can be migrated to DRAM. To realize this, we have used Selection and Run-time Scheduling of page Migration (SRS-Mig), a frame-based scheduling approach for migrations and read/write requests. SRS-Mig reduces migration overhead and guarantees future accesses to migrated pages to yield an improved execution time and memory response time for the applications. Experimental evaluation shows 30% improvement in execution time; 26% improvement memory response time, and considerable energy savings with the existing baseline techniques.","PeriodicalId":188228,"journal":{"name":"Proceedings of the Great Lakes Symposium on VLSI 2022","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126526265","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}

In this paper, we propose a probabilistic prediction processing system, dubbed P3S, to eliminate redundant compute-heavy convolution operations by predicting whether output activations are zero-valued. By exploiting the probability characteristic of Gaussian-like distributed activations and weights in CNNs, P3S calculates the partial convolution across values greater than a standard deviation-related threshold, to predict the ineffectual output activations. P3S skips remaining convolutions and sets outputs to zero in advance if output activations are predicted to be zero. P3S reduces 67% computations within 0.2% accuracy loss and does not even require retraining or fine-tuning CNNs. We further implement a P3S-based CNN accelerator that achieves 2.02x speedup and 2.23x energy efficiency on average over the traditional accelerator. Compared with the state-of-the-art prediction-based accelerator with 3% accuracy degradation, our P$^3$S yields up to 1.49x speedup and 1.69x energy efficiency.","PeriodicalId":188228,"journal":{"name":"Proceedings of the Great Lakes Symposium on VLSI 2022","volume":"04 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130520273","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}

Bufferless NoC has emerged as a popular design choice to address area and energy concerns associated with buffered NoC systems. For low to medium injection rate applications, both bufferless and buffered routers show similar network performance. As the network load rises, network performance of bufferless router based designs deteriorate due to increased deflections. This paper proposes a subnetwork based bufferless design, DAReS, to minimize deflections by redirecting contending flit in one subnetwork to unoccupied productive ports of other subnetwork without incurring any extra cycle delay. From evaluations, we observe that our proposed design approach improves network performance by minimizing deflection rate, power dissipation and shows better throughput in comparison to state-of-the-art bufferless router.","PeriodicalId":188228,"journal":{"name":"Proceedings of the Great Lakes Symposium on VLSI 2022","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134619423","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}

Edge inference, in which inference is performed locally in embedded systems with limited power resources, is researched for its energy efficiency. An approximate encoder is proposed in this study for decreasing switching activity, which minimizes power consumption in CNN accelerators at the edge. The proposed encoder performs approximate encoding based on a pattern matching of a comparison pattern and current data. Software determines the value of the comparison pattern and the availability of the recommended encoder. Experiments with a CIFAR-10 dataset utilizing LeNet5 show that using the suggested encoder, depending upon the comparison pattern, power consumption of a CNN accelerator can be reduced by 21.5% with 1.59% degradation on inference quality.","PeriodicalId":188228,"journal":{"name":"Proceedings of the Great Lakes Symposium on VLSI 2022","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114188369","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}

An SR-latch cascading scheme is presented to further improve the speed and energy efficiency for large TCAM array. Additionally, a same clock phase cascading scheme is proposed to reduce latency in cascading structure, by placing evaluation phase of all stages in the same clock phase. With the suggested ML booster, our 64-bit 1-stage design has speed and energy consumption matching the best performance reported by other emerging non-volatile memory (eNVM) based TCAM design.

In this paper, we study the security of basic LUT-based locking against a set of oracle-less attacks, i.e. attacks that do not have access to a functional oracle of the original circuit. Specifically we perform cut graph/truth-table prediction using deep and graph neural networks with various data encoding strategies. Overall we observe that naive LUT-based locking with small cuts with 2 or 3 inputs may be vulnerable to oracle-less approximation whereas such attacks become less feasible for higher cut sizes. We open source our software for this attack.","PeriodicalId":188228,"journal":{"name":"Proceedings of the Great Lakes Symposium on VLSI 2022","volume":"509 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122628027","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}
