Future designs are expected to improve their capabilities and performance by incorporating novel features, such as emerging neuromorphic devices and analog computation. There is, however, a lack of high-level performance estimation tools to evaluate the impact of such features at the architectural level, to evaluate architectural tradeoffs, and to aid with co-design and design-space exploration. Existing neuromorphic simulators either do not consider hardware performance, only model abstract SNN dynamics or are targeted to a single specific architecture. In this work, we propose SANA-FE, a novel simulator that can rapidly and accurately estimate performance and energy efficiency of different SNN-based designs. Our simulator uses a general and configurable architecture description format that can specify a wide range of neuromorphic designs. Using such an architecture description, SANA-FE simulates system activity when executing a given spiking application at an abstract time-step granularity, and it uses activity counts and per-activity performance metrics to estimate energy and latency for each time-step. We further show a calibration methodology and apply it to model performance of Intel’s Loihi platform. Results demonstrate that our simulator can predict Loihi’s energy and latency for three real-world applications, within 12% and 25%, respectively. We further model IBM’s TrueNorth architecture, simulating a random network over <inline-formula> <tex-math>$20times $ </tex-math></inline-formula> faster than existing discrete-event-based TrueNorth simulators. Finally, we demonstrate SANA-FE’s design-space exploration capabilities by optimizing a Loihi baseline architecture for two application, reducing run-time by 21% while increasing dynamic energy usage by only 2%.","PeriodicalId":13251,"journal":{"name":"IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems","volume":"44 8","pages":"3165-3178"},"PeriodicalIF":2.7,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144663731","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When in-field testing is performed periodically, some of the test periods may be shorter than others. Short test periods should focus on the faults that are the most likely to occur with aging, whereas long test periods can apply a more comprehensive test set. This article studies this scenario in the context of a logic built-in self-test (LBIST) approach that partitions compressed tests into subvectors for on-chip storage, and combines subvectors into compressed tests on-chip using counters. This approach has low storage requirements, allows complete fault coverage to be achieved, and uses a moderate number of tests. The problem of applying a small number of tests during a short testing period is formulated as a static problem of rearranging the subvectors (with possible repetitions and modification) such that the first <inline-formula> <tex-math>$n_{1}$ </tex-math></inline-formula> subvectors are sufficient for detecting a subset of faults <inline-formula> <tex-math>$F_{1}$ </tex-math></inline-formula>, and <inline-formula> <tex-math>$n_{1}$ </tex-math></inline-formula> is as small as possible.

In recent years, PUFs based on resistive random access memory (RRAM) have demonstrated excellent reliability and integration density. Most previous designs store PUF keys directly in RRAMs, increasing vulnerability to attacks. This article proposes a dual-mode RRAM PUF, named differential mode and flexible mode, utilizing the difference in switching capability between RRAMs during parallel SET operations as the entropy source. The proposed PUF can reliably reproduce keys between cycles, so a key concealment scheme is used to protect PUF keys from being continuously exposed, improving the security of the RRAM PUF. The proposed RRAM PUF exhibits high reliability over ±10% VDD and a wide temperature range from −25°C to 125°C through post-processing operations. The flexible mode can generate a significant number of keys for high-security applications. Since the PUF keys can be concealed, the proposed PUF is compatible with in-memory computing. It can be implemented using the same RRAM array as experimentally validated using a MAGIC operation, thus reducing the hardware overhead.","PeriodicalId":13251,"journal":{"name":"IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems","volume":"44 8","pages":"2870-2882"},"PeriodicalIF":2.7,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144657471","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, existing methods often struggle to place data at the optimal cache level promptly due to their reliance on historical access patterns and inflexible placement strategies. These methods face two main challenges: 1) for already cached data with sufficient access history, existing approaches only optimize movement between adjacent cache levels, potentially delaying data arrival at its globally optimal cache level and leading to unnecessary bandwidth consumption and increased latency and 2) for newly entered data without access history, current methods cannot accurately predict their future hotness and simply place them at a fixed cache level (i.e., first or final level), overlooking future accesses of new data and potentially resulting in high cache miss rates or cache pollution. To address these issues, we propose CMCache, an adaptive cross-level data placement method for multilevel cache. CMCache applies distinct placement strategies for cached and new data to reach the optimal level timely, considering their different characteristics. It also logically divides cache space into two sections to manage cached and new data separately, dynamically adjusting section sizes based on access patterns. This approach significantly improves data placement efficiency, achieving up to an 89% reduction in miss rates and a 79% decrease in average response times compared to existing methods.","PeriodicalId":13251,"journal":{"name":"IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems","volume":"44 8","pages":"2911-2924"},"PeriodicalIF":2.7,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144657469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, worst-case PVT and workload conditions rarely occur in practice, resulting in significant timing slack and hence performance and energy loss, especially in reconfigurable dataflow accelerator RDA due to their large-scale and configurable features. Previous studies have attempted to exploit workload or PVT slack, yet achieving limited benefits for reconfigurable dataflow accelerator (RDAs) with large-scale processing element PE arrays. The key issues come from restricted scaling ranges for the clock, insufficient representations for the workload, and unbalanced workloads within processing elementss (PEs). To address these challenges, this article proposes the first multidomain collaborative adaptive clock scheme (MACS) to efficiently exploit both the workload and PVT timing slack for large-scale reconfigurable dataflow acceleratorss (RDAs). MACS partitions the RDA into several clock domains and allows constrained clock domain crossing, which enhances the hardware efficiency with minimal overhead and supports timing validation using conventional static timing analysis (STA) tools. In each domain, an operand-aware workload detection unit is developed, using both static configurations and dynamic operands to assess workload. The detected workload, combined with the monitored PVT conditions, determines the subsequent clock period. Additionally, to enable the exploration of timing slack over a broader range, the period range of the adaptive clock is extended. Experimental results show that MACS achieves a performance improvement of 76.3% or an energy saving of 36.6% with a hardware cost of 3.5%.","PeriodicalId":13251,"journal":{"name":"IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems","volume":"44 8","pages":"2992-3005"},"PeriodicalIF":2.7,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144657396","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we develop a Zram instance pool framework called ZramPool for adaptive memory compression. The framework consists of the swap space with multiple Zram instances and the adaptive Zram compression module. Through introducing linear regression analysis, the number of Zram instances can be adaptively adjusted based on the size of the compressed data, allowing Zram instances to work in parallel to match the workload. In ZramPool, we achieve two different requirements of reducing CPU utilization while keeping compression speed and increasing compression speed while keeping CPU utilization. ZramPool is deployed in the embedded Linux OS with a 8GB memory size running on the ARMv8 architecture. For the first requirement, ZramPool can reduce CPU utilization by an average of 11.42% while the compression speed only decreases by an average of 2.4%.
