Member Function Documentation

◆ getMappedMem()

virtual MappedMemory etiss::plugin::MemMappedPeriph::getMappedMem ( ) const

pure virtual

Defines in which memory region to map this peripheral.

Referenced by getWrapInfo().

Here is the caller graph for this function:

◆ getWrapInfo()

ETISS_System etiss::plugin::MemMappedPeriph::getWrapInfo ( ETISS_System * origSystem )

finalvirtual

Defines which System functions to wrap.

Initialize an ETISS_System struct to zero and only set the fields of the functions that this plugin should wrap. The handle field may be set to a custom data structure that will be passed to the wrapped functions as first argument.

Parameters

origSystem The System that is being wrapped. Must be stored by the plugin to fall back to the parent System.

Implements etiss::plugin::SelectiveSysWrapper.
