The Fixed-Point Blockset offers extensive support for datatypes. Fixed-point blocks support inheritence and propagation of data type and scaling information from between blocks in the model. This capability can be used to significantly reduce the amount of configuration information you need to supply.
All blocks generate pure integer code, when used with fixed-point signals and parameters.
