Third-party intellectual property (3PIP) cores are widely used in integrated circuit designs. It is essential and important to ensure their trustworthiness. Existing hardware trust verification techniques suffer from high computational complexity, low extensibility, and inability to detect implicitly-triggered hardware trojans (HTs). To tackle the above problems, in this paper, we present a novel...
Many companies are deploying services, either for consumers or industry, which are largely based on machine-learning algorithms for sophisticated processing of large amounts of data. The state-of-the-art and most popular such machine-learning algorithms are Convolutional and Deep Neural Networks (CNNs and DNNs), which are known to be both computationally and memory intensive. A number of neural network...
Ray tracing, as a global illumination based rendering method, is famous for generating high-fidelity images of 3D scene and is widely used in computer graphics. Implementations of ray tracing based on Central Processing Unit (CPU), Graphic Processing Unit (GPU) and Field-programmable Gate Array (FPGA) have been proposed in the past few decades. In this paper, we present a hardware acceleration engine...
Firewalls are critical security devices handling all traffic in and out of a network. Firewalls, like other software and hardware network devices, have vulnerabilities, which can be exploited by motivated attackers. However, because firewalls are usually placed in the network such that they are transparent to the end users, it is very hard to identify them and use their corresponding vulnerabilities...
In this paper, we propose an effective macroblock (MB) layer rate control (RC) scheme with low complexity for efficient H.264/AVC video encoder hardware implementation. Linear mean absolute difference (MAD) prediction is crucial in H.264/AVC rate control. The MAD prediction accuracy in JVT G012 is imperfect with high complexity. Therefore we propose a new MAD prediction arithmetic which computes MAD...
At present many cities in our country have massive plans in constructing comprehensive transportation hubs. To realize security operation of it well, the paper proposes establishing "the regional security monitoring center" in the hubs. It can realize different complex transportation supervisory system's information sharing and the seamless connection. Firstly, the paper discusses on the...
