The phase-change random access memory (PRAM) technology is fast maturing to production levels. Main advantages of PRAM are non-volatility, byte addressability, in-place programmability, low-power operation, and higher write endurance than that of current flash memories. However, the relatively low write bandwidth and the less-than-desirable write endurance(More)
The number of cores in a single chip multiprocessor is expected to grow in coming years. Likewise, aggregate on-chip cache capacity is increasing fast and its effective utilization is becoming ever more important. Furthermore, available cores are expected to be underutilized due to the power wall and highly heterogeneous future workloads. This trend makes(More)
BACKGROUND Control algorithms that regulate blood glucose (BG) levels in individuals with type 1 diabetes mellitus face several fundamental challenges. Two of these are the asymmetric risk of clinical complications associated with low and high glucose levels and the irreversibility of insulin action when using only insulin. Both of these nonlinearities(More)
A key design issue for chip multiprocessors (CMPs) is how to exploit the finite chip area to get the best system throughput.The most dominant area-consuming components in a CMP are processor cores and caches today.There is an important trade-off between the number of cores and the amount of cache in a single CMP chip.If we have too few cores, the system(More)
Type 1 diabetes is characterized by a lack of insulin production by the pancreas, causing high blood glucose concentrations and requiring external insulin infusion to regulate blood glucose. Continuous glucose sensors can be coupled with continuous insulin infusion pumps to create a closed-loop artificial pancreas. A novel procedure of ‘‘human-friendly’’(More)
This paper considers the use of constrained minimum crest factor multisine signals as inputs for plant-friendly identification testing of chemical process systems. The methodology presented here effectively integrates operating restrictions, information-theoretic requirements, and state-of-the-art optimization techniques to design minimum crest factor(More)
OBJECTIVE The purpose of this study was to develop an advanced algorithm that detects pending hypoglycemia and then suspends basal insulin delivery. This approach can provide a solution to the problem of nocturnal hypoglycemia, a major concern of patients with diabetes. RESEARCH DESIGN AND METHODS This real-time hypoglycemia prediction algorithm (HPA)(More)
The slow speed of conventional execution-driven architecture simulators is a serious impediment to obtaining desirable research productivity. This paper proposes and evaluates a fast manycore processor simulation framework called two-phase trace-driven simulation (TPTS), which splits detailed timing simulation into a trace generation phase and a trace(More)
The term “plant-friendly” system identification has been used within the chemical process control research community in reference to the broad-based goal of accomplishing informative identification testing while meeting the demands of industrial practice. While many different identification topics (such as control-relevant identification, closed-loop(More)
This paper proposes and studies a distributed L2 cache management approach through page-level data to cache slice mapping in a future processor chip comprising many cores. L2 cache management is a crucial multicore processor design aspect to overcome non-uniform cache access latency for high program performance and to reduce on-chip network traffic and(More)
