A novel field programmable gate array (FPGA) implementation of content-based music retrieval system is presented in this paper. The system adopts a novel hardware architecture for approximate string matching. The architecture is based on a simple shift-and-or algorithm. It has the advantages of low area cost and high throughput. Numerical results show that the proposed architecture has significantly...
This paper describes a direct phase control scheme for unity power factor three-phase buck type rectifier modulated with space vector PWM method (SVPWM). The advantages of the developed system are low harmonic distortion in AC supply currents, nearly unity power factor over wide operating scope, easily realization. The theory analysis and modeling method are introduced first. Second, the control scheme...
A self-sampling PI (proportional-integral) control all digital phase-locked loop (ADPLL) is introduced in this paper. Our design is based on the self-sampling PI control scheme. An advantage of this is that the transfer function as linear approximation of the system model remains almost the same at different lock point, a feature enabling theoretical analysis and systematic design. The complete design...
