In this paper we describe an implementation of the Given rotations using the High speed logarithmic arithmetic (HSLA) library. This library is used for an efficient implementation of the floating-point arithmetic operation in FPGA (including the square root operation). The library was used to implement Given rotations in the Xilinx XCV2000E. The implementation was realised using some rapid prototyping tools for signal processing applications and for the FPGA design.
