MSB” etc.). Fixed point MATLAB code is therefore slower than a oating point one. In
addition, the data-type proposition is done based on empirical simulation data. Therefore,
to have a good data-type estimation the wizard must collect substantial variable value sta-
tistics. Such collection might have forced longer simulation times. Luckily, to mitigate this
seemingly considerable drawback, prior to running in the Fixed Point Designer wizard,
all MATLAB function code is auto-converted ...
