-Cacheability is a segment attribute, and is implemented by the [wiki:Component/VciXcache VciXcache] component. As this component does not implement a MMU, it contains a dedicated address decoder to determine the cacheability. This decoder is implemented as a '''Cacheability Table''',  that is accessed by the cache controller for each processor request. This table is indexed by the address bits selected by the cacheability mask. The table output is a Boolean defining the cacheability.
+Cacheability is a segment attribute that can be exploited by some cache controllers such as [wiki:Component/VciXcacheWrapper VciXcacheWrapper] component. As this component does not implement a MMU, it contains a dedicated address decoder to determine the cacheability. This decoder is implemented as a '''Cacheability Table''',  that is accessed by the cache controller for each processor request. This table is indexed by the address bits selected by the cacheability mask. The table output is a Boolean defining the cacheability.
 
 The content of the '''Cacheability Table''' is automatically constructed by a method of the mapping table.
