Float vs fixed point
WebDec 16, 2024 · If fixed-point will satisfy the mathematical requirements, especially with smaller sizes like 16 bits or less, then fixed-point will almost always be more efficient for both microprocessors and FPGAs. But fixed-point will require more engineering design effort to select the optimal bit sizes and scalings. Web1.1 Fixed-point or floating-point One alternative to floating-point is fixed-point, where the exponent field is fixed. But if fixed-point is giving better calculation speed on FPU-less processors, the range of numbers and their dynamic is low. As a consequence, a developer using the fixed-point technique will

WebThe greater accuracy of the floating-point format results from three factors. First, the 24-bit word width in TI C67x™ floating-point DSPs yields greater precision than the C62x™ 16-bit fixed-point word width, in integer as well as real values. Second, expo-nentiation vastly increases the dynamic range available for the application. A wide
