Contemporary mobile platforms use mobile GPUs for graphics-intensive applications, and deploy proprietary Dynamic Voltage Frequency Scaling (DVFS) policies in an attempt to save energy without sacrificing quality. However, there have been no previous systematic studies to correlate the performance, power, and energy efficiency of mobile GPUs based on(More)
The increasing amount of computation in heterogeneous architectures (including CPU and GPU cores) puts a big burden on memory subsystem. With the gap between compute units and the memory performance getting wider, designing a platform with a responsive memory system becomes more challenging. This issue is exacerbated when memory systems have to satisfy a(More)
Mobile platforms are increasingly using Heterogeneous MultiProcessor Systems-on-Chip (HMPSoCs) with differentiated processing cores and GPUs to achieve high performance for graphics-intensive applications such as mobile games. Traditionally, separate CPU and GPU governors are deployed in order to achieve energy efficiency through Dynamic Voltage Frequency(More)
Modern mobile heterogeneous platforms have GPUs integrated with multicore processors to enable execution of highend graphics-intensive games. However, these gaming applications consume significant power due to heavy utilization of CPU-GPU resources, which drains battery resources that are critical for mobile devices. While Dynamic Voltage and Frequency(More)

Network Intrusion Detection Systems (NIDS) are more and more important for identifying and preventing the malicious attacks over the network. This paper proposes a novel cost-effective high speed pattern matching algorithm (named MSH) for NIDS. By applying the characteristics of magic states, a new observation from the deterministic finite state automata(More)
Network Intrusion Detection Systems (NIDS) are more and more important in today’s network security for identifying and preventing malicious attacks over the network. This paper proposes a novel and effective string matching algorithm (named ACMS) with advantages of both compact memory and high performance. By employing the characteristics of magic states(More)
To create a Chinese font, even for professional font designers, it still has to take a lot of time and efforts. A Chinese font typically packs glyphs of several thousand or more Chinese characters, and many of them are very complicated. Previously we had presented an easy and fast solution for an ordinary user to create a Chinese font of his or her(More)
