In this paper, we disclosure a cost-efficiency FFT via hardware-reduction and dynamic current scaling (DCS) schemes in a low-power OFDM modem. These reductions are realized by the pipelined data path modifying and the hardware sharing at two stages. For low power, the operating current is scalable to reduce power consumption, namely DCS. All our works are synthesized and simulated by the TSMC 65nm...
The development of industry informationization and electronic commerce (e-commerce) promote the emergence of electronic market (e-market). One called electronic exchange (e-exchange) is a typical business model. It requires a higher security level for the business operating system. This paper systematically studies the e-exchange security problems from the view of e-commerce security, analyzes the...
