[VHDL-FPGA-Verilogmagnitude

Description: Verilog HDL: Magnitude For a vector (a,b), the magnitude representation is the following: A common approach to implementing these arithmetic functions is to use the Coordinate Rotation Digital Computer (CORDIC) algorithm. The CORDIC algorithm calculates the trigonometric functions of sine, cosine, magnitude, and phase using an iterative process. It is made up of a series of micro-rotations of the vector by a set of predetermined constants, which are powers of two. Using binary arithmetic, this algorithm essentially replaces multipliers with shift and add operations. In a Stratix™ device, it is possible to calculate some of these arithmetic functions directly, without having to implement the CORDIC algorithm. -Verilog HDL : For a vector magnitude (a, b), the magnitude representation is the following : A common approach to implementing thes e arithmetic functions is to use the Coordinate Rotation Digital Computer (CORDIC) algorithm.
