| Summary: | The traditional method for solving trigonometric functions utilizing look up tables or the power series takes a lot of time and memory space in digital computers than necessary. A method of equal effectiveness is the vector rotation.
The trigonometric algorithm using this concept is called the Coordinate Rotation Digital Computer or CORDIC. It is a kind of shift-add algorithm that provides iterative vector rotations by arbitrary angles without actually multiplying - instead simple shift operation is used. The implementation of CORDIC algorithm using FPGA would provide a hardware-based approach to solve such trigonometric functions in a faster rate and memory space-saving manner.
This thesis would perform computation for sine, cosine, and tangent functions, their inverses, as well as polar-to-rectangular and rectangular-to-polar coordinate conversions using the CORDIC algorithm with VHDL as the design entry tool. |
