Method for disseminating scaling information and application thereof in VLSI implementaton of fixed-point FFT. Interuniversitair Micro-Electronica Centrum vzw
1. A scaling information propagation method, wherein the method is applied to achieve bitwidth-optimized and energy-efficient hardware implementation of linear decomposable transform in the digital signal processing (DSP) and comprises: At the design phase, reversing the subsequent linear decomposable transform procedure as the previous linear decomposable transform procedure (our focused system contains a pair consisting of a linear decomposable transform and its inverse). At the design phase, inserting gathering scaling information module and making scaling decisions module in the previous ...
