WebFixed-Point Designer provides apps and tools for analyzing double-precision algorithms and converting them to reduced-precision floating point or fixed point. Optimization tools enable you to select data types that meet your numerical accuracy requirements and target hardware constraints. Webimplemented on a fixed-point processor is needed. The block floating point algorithm is based on the block automatic gain control (AGC) concept. Block AGC only scales values at the input stage of the FFT. It only adjusts the input signal power. The block floating point algorithm takes it a step further by tracking the signal strength from stage numerically scaled thermometer
