Perform Binary-Point Scaling - MATLAB & Simulink

WebSimulations were performed using Matlab and fixed-point C. Implementation was in highly optimized TI TMS320C54x assembly. ... * Scaling and overflow analysis of fixed-point algorithms. WebFixed-Point Designer supports general binary point scaling V = Q 2E, where V is the real-world value, Q is the stored integer value, and the fixed exponent E is equal to the negative of the fraction length. In other words, RealWorldValue = StoredInteger 2−FractionLength. The fraction length defines the scaling of the stored integer value.
