In general Application Specific Integrated Circuits (ASIC) and Digital Signal Processors (DSP) are usually used for implementing digital filters. As compared to the conventional methods available the speed of computation of digital filter is increased by implementing on field programmable logic gate array (FPGA). This paper provides a novel design and implementation of digital filter in FPGA using a high level description tool like Xilinx System Generator. The designed filter with desired specification is analyzed in Simulink environment in MATLAB. A method for implementing IIR filter in FPGA using System Generator is proposed. The Xilinx system generator is used for synthesizing and simulation for FPGA filter analysis. The FPGA shows its high performance in terms of speed, memory, resource management, and power consumption.

In recent years,the multi-element phase-controlled transducer used in high intensity focused ultrasound(HIFU) treatment have attracted the attention of many researchers due to their advantages such as adjustable focal *** phase control and drive system of the multi-element phase-controlled transducer is one of the key factors that determine whether it can be used in clinical *** this paper,a field programmable logic gate array(FPGA),a high-speed digital-to-analog converter and an integrated power amplifier are used to design a phase control and drive system for multi-element phase-controlled transducer for high intensity focused ultrasound *** system has functions of multichannel output and real-time transmission of delay data of each channel by the personal *** actual measurement results show that the peak-to-peak value of the output sine wave signal of each channel of the system can reach 35.3 V,the phase resolution can reach 1 ns,the delay error is less than 1 ns,and the output signal has no high-order harmonic interference,which meets the phase resolution and driving requirements of multi-element phase-controlled transducer applied in clinical treatment.
