    116116== 4) Cacheability Table == 
    117117 
    118 Cacheability is a by-segment attribute. Cacheability 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'''.  
    119 This table is accessed by the cache controller for each processor request. This table is indexed by the  
    120 address bits defined by the cacheability_mask, and contains the Boolean defining the cacheability.
