Abstract
A data compression utilization method and apparatus are provided for a computer main store. An amount of unused memory in the computer system main store is dynamically calculated and compared with a plurality of predefined threshold values. One interrupt of a plurality of predefined interrupts is selectively generated responsive to the compared values. Then the usage of the computer system main store is adjusted responsive to the generated interrupt.
Claims10
An apparatus for utilizing data compression in a computer system main store comprising:
- means for dynamically calculating an amount of unused memory in the computer system main store and for comparing the calculated amount with a plurality of predefined threshold values;
- means responsive to said compared values for selectively generating one interrupt of a plurality of predefined interrupts;
- and
- means responsive to said generated interrupt for adjusting the usage of the computer system main store.
A method for utilizing data compression in a computer system main store, said method comprising the steps of:
- dynamically calculating an amount of unused memory in the computer system main store and comparing the calculated amount with a plurality of predefined threshold values;
- selectively generating one interrupt of a plurality of predefined interrupts responsive to said compared values;
- and
- adjusting the usage of the computer system main store responsive to said generated interrupt.
