Vector magnitude calculation is significant in the QR-algorithm by Coordinate Rotation Digital Computer (CORDIC), which is increasingly used in adaptive applications. However, its hardware implementation is extremely difficult. In this paper, a fixed point CORDIC system is constructed to compute the magnitude of a vector by using Model-Based Design. The simulation results show that the proposed method of CORDIC vector magnitude calculator is not only simple in structure and easy to implement,

... d can improve the speed of operation with good scalability. Model-Based Design is introduced. A fixed point CORDIC system is constructed to compute the magnitude of a vector in Section 4. Finally, concluding remarks are drawn in Section 5.
