This paper presents a device model for nanoelectronic resistive switches which are based on the electrochemical metallization effect (ECM). The focus is set on modeling variability as well as irreproducibility which are essential properties of scaled nanoelectronic devices. In particular, a Poisson-based random ion deposition model and a non-linear filament surface effect are described. The model is especially useful for circuit simulation and can be implemented on standard circuit simulation platforms such as Spice or Spectre using inbuilt standard elements. Based on this model, effects of variability were examined by Monte Carlo simulation for a particular hybrid CMOS/nanoelectronic circuit. The results show that the proposed model is able to cover significant scaling effects, which is necessary for prospective design space exploration and circuit optimization.

In High-level Synthesis, scheduling has a critical impact on the quality of hardware implementation. However, the schedules of different operations are actually having unequal impacts on the Quality of Result. Based on this fact, we propose a novel scheduling framework, which is able to schedule the operations separately according their significance to Quality of Result, to avoid wasting the computational efforts on noncritical operations. Furthermore, the proposed framework supports global code motion, which helps to improve the speed performance of the hardware implementation by distributing the execution time of operations across the their parent BB.

In this paper we are interested in flow-based microfluidic biochips, which are able to integrate the necessary functions for biochemical analysis on-chip. In these chips, the flow of liquid is manipulated using integrated microvalves. By combining several microvalves, more complex units, such as micropumps, mixers, and multiplexers, can be built. In this paper we propose, for the first time to our knowledge, a top-down control synthesis framework for the flow-based biochips. Starting from a given biochemical application and a biochip architecture, we synthesize the control logic that is used by the biochip controller to automatically execute the biochemical application. We also propose a control pin count minimization scheme aimed at efficiently utilizing chip area, reducing macro-assembly around the chip and enhancing chip scalability. We have evaluated our approach using both real-life applications and synthetic benchmarks.

Real-time task scheduling becomes even more challenging with the emerging of island-based multi-core architecture, where the local memory module of an island offers shorter access time than the global memory module does. With such a popular architecture design in mind, this paper exploits real-time task scheduling over island-based homogeneous cores with local and global memory pools. Joint considerations of real-time scheduling and memory allocation are presented to efficiently use the computing and memory resources. A polynomial-time algorithm with an asymptotic 4-approximation bound is proposed to minimize the number of needed islands to successfully schedule tasks. To evaluate the performance of the proposed algorithm, 82 benchmarks from the MRTC, MediaBench, UTDSP, NetBench, and DSPstone benchmark suites were profiled by a worst-case-execution-time analyzer aiT and included in the experiments.

Multi-core system simulation techniques have been especially essential to system development in recent years. Although these techniques have been studied extensively, we have found that both conventional polling and collaborative timing synchronization approaches all encounter a severe scalability issue when the number of target cores is more than that of the host cores. To resolve this issue, we propose an effective hybrid technique that combines the advantage of the two approaches. According to the experimental results, the proposed technique effectively resolves the scalability issue and shows one to four orders of improvement compared to conventional approaches.

An extremely low-voltage operating high speed and low power 2bit/step asynchronous SAR ADC is presented. Wide range dynamic threshold configuring comparator is proposed to enable power and area efficient 2bit/step operation. By configuring the comparator threshold by simple Vcm biased current sources, the ADC holds immunity against 10% power supply variation. The prototype ADC fabricated in 40nm CMOS achieved 44.3 dB SNDR with 6.14 MS/s at a single supply voltage of 0.5 V. The ADC achieved a peak FoM of 5.9fJ/conv-step at 0.4V and operates down to 0.35V.

This work presents an iterative look-up table based thermal simulator, I-LUTSim, to efficiently estimate the temperature profile of three-dimensional integrated circuits. I-LUTSim includes two stages. First, the pre-process stage constructs thermal impulse response tables. Then, the simulation stage iteratively calculates the temperature profile via the table lookup. With this two-stage scheme, the maximum absolute error of I-LUTSim is less than 0.41% compared with that of a commercial tool ANSYS. Moreover, I-LUTSim is at least an order of magnitude faster than a fast matrix solver SuperLU [1] for the full-chip temperature simulation.

Microfluidic biochips have been recently proposed to integrate all the necessary functions for biochemical analysis. There are several types of microfluidic biochips; among them there has been a great interest in flow-based microfluidic biochips, in which the flow of liquid is manipulated using integrated microvalves. By combining several microvalves, more complex resource units such as micropumps, switches and mixers can be built. For efficient execution, the flow of liquid routes in microfluidic biochips needs to be scheduled under some resource constraints or routing constraints. The execution time of the biochemical operations depends on the binding and scheduling results. The most previously developed binding and scheduling algorithms are based on heuristics, and there has been no method to obtain optimal results. Considering the above, this paper proposes an optimal method by casting the problem to a clique problem.

With an efficient intra prediction design, its maximum throughput reaches 1991Mpixels/s for 7680×4320p 60fps video, 9.4x to 32x faster than previous designs. The encoder also incorporates a 1.41Gbins/s CABAC architecture that has been enhanced by 31%. Moreover, low energy consumption is achieved by the high parallelism and hardware efficiency of this design. 1080p 30fps encoding dissipates only 2mW at 0.8V and 9MHz.
