Abstract :
New advancement in FPGA-DSP technology demands a new number system as well as a new data treatment that best utilizes the strengths and avoid the shortcomings of the new technology. To achieve this goal, here we introduce a customized floating-point number system that it can be reformatted as a fixed-point number when needed. In addition, a scheme is proposed for the use of both formats in DSP applications, such as in digital filter design.
