The increasing resolutions combined with storage and processing limitations of mobile devices point to the need for new compression techniques for video coding. Meanwhile, to achieve higher compression rates without compromising quality, the coding process becomes more and more complex. In reference software of HEVC the most time consuming step is the execution of Motion Estimation (ME), which is...

There has been a growing trend in recent years to outsource various aspects of the semiconductor design and manufacturing flow to different parties spread across the globe. Such outsourcing increases the risk of adversaries adding malicious logic, referred to as hardware Trojans, to the original design. In this paper, we introduce a run-time hardware Trojan detection method for microprocessor cores...
This paper presents a complete on-chip ADC BIST solution based on a segmented stimulus error identification algorithm known as USER-SMILE. By adapting the algorithm for efficient hardware realization, the solution is implemented towards a 1Msps 12-bit SAR ADC on a 28nm CMOS automotive microcontroller. While sufficient test accuracy is demonstrated, the solution is further extended to correct linearity...
Prognostic diagnosis is desirable for commercial core router systems to ensure early failure prediction and fast error recovery. The effectiveness of prognostic diagnosis depends on whether anomalies can be accurately detected before a failure occurs. However, traditional anomaly detection techniques fail to detect “outliers” when the statistical properties of the monitored data change significantly...
In this paper, we present CORT, a factored concolic execution based methodology for high-level functional test generation. Our test generation effort is visualized as the systematic unraveling of the control-flow response of the design over multiple explorations. We begin by transforming the Register Transfer Level (RTL) source for the design into a high-performance C++ compiled functional simulator...

Electronic spreadsheet and independent interface configuration is the key research points to realize hot-plug function. After testing, system can be used in electric transmission line leakage current and voltage detection...
There is an increasing demand in the society for an accurate cost sensitive compact biosensor. This is due to the fact that this kind of biosensor can slightly decrease the diagnosis period of diseases, which has major importance on the treatment period. Also it would not require facilities or expertise which is only available in hospital laboratories. Optical biosensors can offer very sensitive and...
Very large-scale Deep Neural Networks (DNNs) have achieved remarkable successes in a large variety of computer vision tasks. However, the high computation intensity of DNNs makes it challenging to deploy these models on resource-limited systems. Some studies used low-rank approaches that approximate the filters by low-rank basis to accelerate the testing. Those works directly decomposed the pre-trained...

The main hardware components are a XC7A75T FPGA performing almost all the computations, a TMS320C6746 digital signal processor organizing...
Recent advancements in MEMS microphone integration have led to the production of low-cost digital MEMS microphones which are suitable for applications in the ultrasonic acoustic spectrum. Using these microphones instead of their analog counterparts can greatly simplify board- and system-design and reduce overall construction cost of an array built with these sensors. In this paper we will propose...
Statistics show, that stroke is one of the main causes of death worldwide, and reliable and fast diagnosis is key to recovery. Modern medical imaging devices provide intricate detail, but lack portability and are in some cases invasive.
