This paper proposes a passband lock loop for tunable band-pass-filter (BPF). AC-coupling, swing amplification, peak conversion and low-noise S/H circuit are designed to differentiate several hundred uV of swing difference. All-digital peak-tracking-controller and FSM are also realized for easy verification and low area. The proposed loop was integrated with a BPF cell with 7-bits controls and 30M∼50MHz...
In this work, we propose a reconfigurable near-data systolic array accelerator (NDSAA) for the 3D DRAM systems. The NDSAA supports the iterative operations for different applications, and the data movement between the processor core and the 3D DRAM is reduced. In our experiments, the 3D DRAM stacking the NDSAA reduces the latency by 51% ∼ 70% compared to the one stacking the general bi-directional...
The emerging security analysis challenge in big data environment is getting more attention of security industry and research institute. The current problems are mainly about the volume of security data and the understanding of the data. To solve the problems, we should employ the big data technology, and meantime, consider the semantic processing methods. In this paper, we combine the big data processing...
High output power multiplier is necessary for local oscillator source of terahertz communication. However, single multiplier chip power-handling capability is limited by understandably low efficiency level and other technical constraints. To enhance the power-handling capabilities, we propose a power-combined multiplier architecture based on fundamental frequency vector modulation utilizing double...

It works in the 59–64GHz RF frequency with two 2.16GHz bandwidth IF communication channels in the 8.64GHz. The cavity band pass filters are added in the output of the TX and the LO link to realize the high sideband reject and low spurious. This kind of capacity-loading filter can realize...
We prove a complexity dichotomy for complex-weighted Holant problems with an arbitrary set of symmetric constraint functions on Boolean variables. In the study of counting complexity, such as #CSP, there are problems which are #P-hard over general graphs but P-time solvable over planar graphs. A recurring theme has been that a holographic reduction [Val08] to FKT precisely captures these problems...
In this work, we propose a half-size frequent pattern compression algorithm (HSFPC) for the 3D DRAM system. In the 3D DRAM system, the access data compressed by HSFPC can achieve better compression rate than by the traditional compression method, frequent pattern compression (FPC). In our experiments, the 3D DRAM system using HSFPC can reduce the peak temperature by 0.5 °C ∼ 4.5 °C compared with the...
For the question of information security vulnerabilities discovery, the parallel vulnerabilities discovery method is given based on the CAPEC, CWE, CVE and other open source database and text mining. Firstly, we can extract the association vulnerability CWE under the same attack mode, then from CWE associated with CVE based on open source database. That can help us to analyze the potential parallel...

Freezing of gait (FOG) is a common motor impairment to suffer an inability to walk, experienced by Parkinson's disease (PD) patients. FOG interferes with daily activities and increases fall risk, which can cause severe health problems. We propose a novel smartphone-based system to detect FOG symptoms in an unconstrained way. The feasibility of single device to sense gait characteristic was tested...
Multicast congestion control is essential to avoid congestion collapse and ensure fair competition in bandwidth with unicast.

3D parts inspection can be conducted by comparing the ideal design geometry with the real measurement points. Since the design coordinate system is different from the measurement coordinate system, these measurement points should be registered to the design coordinate system first. In this research area, iterative closest point (ICP) is the best-known algorithm, however, in order to converge to the...
