WebIdeally, floating-point FFT implementations in custom embedded applications should be used because they offer a much higher dynamic range and, as a byproduct, bypass the design hassle of analyzing fixed-point word lengths, including how to properly scale operations to minimize word growth and avoid overflow. WebThe method drastically outperforms Direct-Forcing methods and the standard immersed boundary method for problems with thin dynamic structures. We couple our immersed boundary method with a three-dimensional shell solver via an implicit partitioned approach. A quasi-Newton method solves the resulting fixed-point problem.

WebFloating-point numbers are the favorites of software people, and the least favorite of hardware people. The reason for this is because floating point takes up almost 3X the hardware of fixed-point math. The advantage of floating point is that precision is always maintained with a wide dynamic range, where fixed point numbers loose precision. WebFixed-point systems use the 32 bits in the conventional way to provide an internal dynamic range of about 192dB. Systems that use fixed-point 32-bit processing (like the 0-series … WebC62x™ 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 dynamic range is important in dealing with extremely large data sets and with data sets where the range cannot be easily predicted.
