Abstract
Implementation of universal modulator in Field Programmable Gate Array (FPGA) is very much useful in many real-time applications for its high throughput, low-cost and short time to market. This paper presents pipeline based CORDIC (COordinate Rotation Digital Computer) algorithm is used in universal modulator such as Amplitude Modulator (AM), Frequency Modulator, Phase Modulator (PM). The CORDIC algorithm basically converts the coordinates from polar mode to rectangular mode. In the absence of multiplier and accumulator in CORDIC architecture, the digital realization system using CORDIC architecture can be efficiently optimized at hardware level. It only requires addition, subtraction, bit shifting, and lookup table and hence the system has become energy efficient and also provides accurate result. The design has been codded in Hardware Description Language (HDL) and synthesized by using Xilinx ISE Design Suite 14.7 with Virtex-6 target device. The implementation result shows that proposed system has less slice-delay product compare to previous architecture.
