Abstract

The current ultrasound therapy machines are implementing continuous waveform, which in fact, is not an optimum technique for therapy treatment process. Apparently, pulse waveform appearing as a more effectively way of signal generation in terms of its power consumption, low cost hardware and short timing used. In order to overcome these drawbacks of conventional therapy machines, we proposed a programmable pulse generator for pulse waveform production with high frequency more than 1MHz through Cyclone 2 Field Programmable Gate Array (FPGA) development board. The generator is developed with maximum controllable 10 number of burst and clock frequency 50MHz. Register Transfer Level designs with Very-High-Speed Integrated Circuit Hardware Description Language (VHDL) coding are also implemented throughout this project. Pin assignment was used to assign the pin connection in FPGA for linkage of input and output data of FPGA. The result of generated waveforms were observed using oscilloscope. Based on the findings, the developed programmable FPGA is able to produce high frequency signal effectively and accurately.
