Abstract
Conversion of integer to floating-point number is a frequent operation in high performance DSP processor, and direct conversion is time consuming. An improved method of converting integer to floating point number is presented in this article, in which leading zero is preserved until rounding and complementation are preformed, and normalization is done after rounding, rounding and complementation are combined, so that hardware cost is reduced and complexity of conversion is decreased. The method is used in the design of a DSP processor, and the design is synthesized, verified and implemented with FPGA.
