Fixed point modelling in matlab
WebIn this example, the word length of the product c is equal to the word length of a plus the word length of b. The fraction length of c is also equal to the fraction length of a plus the fraction length of b. a = fi (pi,1,20); b = fi (exp (1),1,16); c = a*b. c = 8.5397 DataTypeMode: Fixed-point: binary point scaling Signedness: Signed WordLength ... WebThe Fixed-Point Tool checks the system under design for compatibility with the conversion process and reports any issues found in the model. When possible, the Fixed-Point Tool automatically changes settings that are not compatible. For more information, see Use the Fixed-Point Tool to Prepare a System for Conversion.
