Detailed Description

template<class BASE = BaseModule<DefaultBase>>
class AHBMaster< BASE >

Almost all models implementing an AHB master interface (except busses) are derived from class AHBMaster. AHBMaster is a convenience class providing an AHB master socket and implementations of various access functions for reading/writing data over the bus. AHBMaster inherits AHBDevice and can be configured for loosely timed (LT) or approximately timed (AT) level of abstraction.

An overview about how to build own components based on AHBMaster is given in Extending the Library.
