In recent years, the stock market plays an important role, which has attracted more and more attentions. The key problem of the stock market prediction is how to design a method to improve the prediction performance. As we know, the biggest challenge is that the stock time series is essentially dynamic, nonlinear, complicated, nonparametric and chaotic. In this paper, we propose a novel method to...
Routing protocols in Vehicular Ad hoc Network (VANET) have drawn lots of attention in recent years, most existing research efforts focus on designing IP-based protocols. In this paper, we present a new routing protocol for VANET based on Named Data Network (NDN). We optimize the routing path by using a new distance metric in the protocol, avoiding the shortcomings of hop-count based metric. Moreover,...
This paper describes a tile-able 16-kByte 6-T SRAM macro in a High-K Metal-Gate (HKMG) 28-nm bulk technology with an operating window from 4.8 GHz at 1.12 V VDD down to 10 MHz at 0.5V, meeting almost all of the Dynamic Voltage Frequency Scaling (DVFS) requirements of Level-1 (L1) caches of a digital microprocessor SOC. It uses an unmodified technology-supported 0.156um2 high-current (HC) SRAM cell...
This paper describes an on-chip intellectual property (IP) testing platform, Universal High Frequency Test structure (UHFTs), which makes logic, memory, and analog / mixed-signal IPs at-speed testable in the same testing structure. Any functional testing pattern can be loaded from an external pattern generator or a tester through standard 5-pin JTAG interfaces operating at 10MHz or below. The on-chip...
A fully-pipelined tile-able 1MB SRAM IP with a 0.127um2 cell in a HKMG 28nm bulk technology has an area of 1.39mm2/MB with 79.2% array efficiency. It operates with 2-cycle latency up to 1GHz. The no-repair hardware has a circuit limited yield of 99.92 and 53% at 100 and 850MHz, respectively with 0.75V VDD. A Data Retention Voltage of 0.42V has been measured.
Managing complex enterprise networks requires an understanding at a fine granularity than traditional network monitoring. The ability to correlate and visualize the dynamics and inter-relationships among various network components such as hosts, users, and applications is non-trivial. Network security visualization is a highlighted topic of network security research in recent years, The existing research...
As technology continues to scale, reducing leakage is critical to achieve energy efficiency. Power gating can potentially save a significant part of leakage but it incurs both energy and performance penalties. Therefore, power gating decisions need to be made carefully. In the current low-power SoC design, an IP core is power gated when it is not operating. In this paper, we explore the IP idle time...
Optimizing memory system performance is critical for delivering high system performance for multimedia applications since they are usually memory intensive. As the number of IP cores in a multimedia MPSoC (Multi-Processor System-on-Chip) continues to increase, system performance will be eventually limited by the memory system. In this paper, we tackle the memory performance issue of multimedida MPSoCs...
This paper puts forward a session-based mobility management in MANET which in an efficient manner meets the requirements of rapid deployment of the network with auto-configuration but no need of manual intervention in disaster-rescue situations. A new system called MMAH, which eliminates the otherwise restrictions of mobility management of Mobile IP in MANET, promises more extensive applications of...
Emergency situations are one of the main potential commercial applications of mobile ad hoc network (MANET). These situations propose three requirements to the network: fast deployment, automatic formation and Internet connection. To fulfill the first and the second requirements, the hosts in the MANET may obtain network configurations by auto-configuration. When the MANET connects to the Internet,...
