7.2.Hardware Abstraction for Header files

This hardware abstraction separates out platform specific member variables and member functions from audio object header file and keeps in hardware abstraction class. Implementation of this class is done in platform specific .cpp file. Accessing the hardware abstraction class members in audio object is done by forward declaring the class in later and instantiating this as a class member. Memory allocation and assignment is done for this instance in initMemRecord and init of the object. Sometimes, it may be needed to access audio object data members inside hardware abstraction class. This requirement is taken care by declaring a back pointer in hardware abstraction class and assigning it to audio object pointer in constructor function. Implementation for ToneControl audio object is completed and code snippets for the same is given below

Hardware Abstraction Class

Below is the implementation example of hardware abstraction class for ToneControl C66 implementation. Here m_ToneCtrlInst is the back pointer to access ToneControl data members in Tone Control hardware abstraction class which is initialized in constructor with CToneControl.
