Each Simulink model input is bound to its corresponding write register and each output is bound to its corresponding read register.
WebA simple embedded system typically has the memory map shown below (ignoring peripheral memory). At the highest level the program can be divided into components - the code and the data it manipulates. The code in an embedded system goes into the flash the the data goes into the RAM if it's mutable and flash or RAM if it's read-only.
