Nevertheless, the controller needs some floating-point calculations, which necessitate expensive computing elements. Moreover, additional bits for implementing arithmetic operations are required for floating point calculation. This research proposed a hardware approach of 64bit floating point to 16-bit fixed-point conversion and vice versa. This conversion method will reduce the bit requirements. Any application which is required 16-bit floating-point calculation can be used this two-way conversion technique. In addition, current <em>dq</em> PI controller uses 16-bit I/O bus. Thus, hardware approach of this two-way conversion is a prerequisite for FPGA realization of current <em>dq</em> PI Controller for FOC-PMSM drive. The outcome of this research is a single chip 16bit to 64bit IEEE 754 standard number format converter for current <em>dq</em> PI controller of FOC-PMSM drive.
