We introduce a number system called "jumping-floating-point" (JFP), which has both the characteristics of the fixed-point and the floating-point number systems. We also introduce a DSP architecture with JFP processing capability. This DSP architecture is feasible and can be applied to traditional fixed-point DSP architecture without too much cost. According to our experiments, the JFP number system has better SNR than the fixed-point number system
