Many scientific or engineering applications involve matrix operations, in which reduction of vectors is a common operation. If the core operator of the reduction is deeply pipelined, which is usually the case, dependencies between the input data elements cause data hazards. To tackle this problem, we propose a new reduction method with low latency and high(More)
Java possesses many advantages for embedded system development, including fast product deployment, portability, security, and a small memory footprint. As Java makes inroads into the market for embedded systems, much effort is being invested in designing real-time garbage collectors. The proposed garbage-collected memory module, a bitmap-based processor(More)
Hardware accelerators such as FPGAs and GPUs in heterogeneous systems are being increasingly important for many applications. For high performance computing, the flexibility and efficiency of FPGA makes it an attractive alternative to other approaches. However, for applications that have to decompose large matrices, not many scalable solutions can be found(More)
Along with the rapid growth of new science and technology, the functions of smartphones become more and more powerful. Nevertheless, everything has two aspects. Smartphones bring so much convenience for people and also bring the security risks at the same time. Malicious application has become a big threat to the mobile security. Thus, an efficiency(More)
This paper introduces a novel FPGA-based signature match co-processor architecture serving as the core of a hardware-based network intrusion detection system (NIDS). The signature match co-processor architecture is based on the shift-or algorithm. The architecture is comprised of simple shift registers, or-gates, and ROMs where patterns are stored. As(More)
Matrix decomposition applications that involve large matrix operations can take advantage of the flexibility and adaptability of reconfigurable computing systems to improve performance. The benefits come from replication, which includes vertical replication and horizontal replication. If viewed on a space-time chart, vertical replication allows multiple(More)
Green computing has been an active research area which studies an efficient use of computing resources. It is a growing import subject that creates an urgent need to train next generation computer scientists or practitioners to think “green.” However, green computing has not yet been well taught in computer science (CS) or computer(More)
