Abstract
This paper introduce a new approach to FPGA implementation of synchro to digital converter using Co-ordinate Rotation Digital Computer CORDIC algorithm. This al- gorithm was the best replacement of analog conversion system by the high resolution digital. CORDIC algorithm used for the fast calculation of elementary functions like multiplication, divi- sion, trigonometric functions. The approach is based on receiving the synchro signals S1 , S2 , and S3 from the synchro motor, and converts them to two perpendicular signals sin signal and cosine signal using solid state Scott-t transformer. Then the a CORDIC circuit receive this signals after converting them to digital and produce the azimuth angle in digital format. This prototype of hardware implementation of CORDIC algorithm used Spartan-III series FPGA, with constraint to area efficiency and throughput architecture. The prototype results show that the conversion time is less than 1 µs which is suitable for real time applications in radar and missile control applications.
