Inter-cell interference (ICI) is always a big issue in orthogonal frequency division multiple access (OFDMA) based communication networks. In this paper, we apply power control to an Improved Fractional Frequency Reuse (IFFR) scheme and investigate the system performance. IFFR scheme divides the whole available resources into two segments: the first segment and the second segment. The first segment...
The past few years have witnessed high-end processors with increasing numbers of cores and larger dies. With limited instruction-level parallelism, chip power constraints, and technology-scaling limitations, designers have embraced multiple cores rather than single-core performance scaling to improve chip throughput. This article examines whether this approach is sustainable by scaling from a state-of-the-art...
This paper proposes a novel unified low cost hardware architecture which can accelerate both RSA and SHA-1. And a scalable and unified crypto function unit is presented to support high performance cryptographic computation in the RISC-like processor. To evaluate the effectiveness of our solution, a low power crypto-processor is proposed to integrate the unified function unit, and the execution time...
High-performance systems are undergoing a major shift as commodity multi-core systems become increasingly prevalent. As the number of processes per compute node increase, the other parts of the system must also scale appropriately to maintain a balanced system. In the area of high-performance computing, one very important element of the overall system is the network interconnect that connects compute...
