Abstract
In a computer system with a virtual addressing mechanism, a process for the de-allocation of physical pages sets, by means of a first pointer (ptr) on a line ( ) of a conversion table ( ) that contains an indicator (Ref) that has been set to a first state (“referenced”) by a processor ( ), the indicator (Ref) to a second state (“non-referenced”) if the state is (“referenced”) and de-allocates the line ( ) if the state is (“non-referenced”). The de-allocation process claimed by the invention sets an indicator (ref) which has been set to the first state (“referenced”) by the processor ( ) on a line ( ) of the conversion table ( ) to a second state (“non-referenced”) if the state is (“referenced”) by means of a second pointer (ptr+&Dgr;) on the line ( ) upon the indication of an attribute value (Co) for said line ( ). The de-allocation process can therefore be used for a cache mechanism.
