  • adjusting a system value that is utilized as an offset for calculating a priority of said components when scheduling access to a specific system resource to yield a modified system value, wherein said modified system value accentuates the effect of said system value so that a resulting priority penalty is greater as the system value increases and said priority penalty is smaller as said system value decreases;

    calculating the priority of said components utilizing said modified system value within a priority calculation, wherein said calculated priority is utilized to schedule access of said components to said specific system resource and is different from a priority calculated with said system value; and

    scheduling said components according to said priority calculated utilizing said modified system value.
