With the emerging of digital convergence, lots of communication services are generated, and the quantity of data grows rapidly. We face the scalability issue to deal with call data records (CDRs) and so are the other telecom companies. This research uses police CDR query as an example with an intension to increase system execution efficiency and scalability and to reduce total cost by applying cloud...
Multi-PE and SIMD architectures are widely utilized to enhance computing power of embedded DSP processors. Design of such architectures may cost vast amount of computing resource. Allocation of computing resources becomes a critical design issue for embedded applications. If suitable hardware configurations and software algorithms can be explored in early design stage, enormous design time can be...
This paper presents a digital hearing aid chip designed for Mandarin user to enhance speech quality and intelligibility. The hearing aid consists of an 18 subbands analysis and synthesis filter bank, insertion gain stage, and three channels wide dynamic range control for the new Mandarin-specific auditory compensation algorithm. A noise reduction block based on multiband spectral subtraction and enhanced...
Conventional timing-optimized synchronous circuit is designed and constrained by the longest critical path delay, i.e. the worst-case design. However, the path delay of the circuit is absolutely data-dependent. In the example of an 8-bit multiplier simulation, for the 10,000 random input patterns, only about 1% of the input patterns exercise the critical path. This fact motivates us to exploit data-dependent...
