| Abstract(in English) | It is well known that the lattice filter is very useful for real-time filtering, and adaptive signal processing because of low sensitivity of filter coefficients. In the configuration of the lattice filter, there are several types for the structure. We discuss the relation between a equivalent circuit model using distributed-constant lines and the equivalent digital lattice filters for signal processing, and introduce a new hardware structure adopting a programmable architecture to realize a flexible DSP on a Field Programming Gate Array (FPGA). In order to realize a system on VLSI including the lattice filter in reasonable cost, we propose a new hardware core and a design method by using VHDL and the components designed by VHDL. We realize a simple speech synthesizer by using our programmable DSP and show the experimental results of our hardware design. |
