Abstract
An adaptive method allocates RAM between procedures having both higher and lower priorities. The RAM is provided with first and second portions, the first portion for assignment to higher priority procedures and the second portion for assignment to lower priority procedures, higher priority procedures being able to access also the second portion of RAM. The adaptive method comprises the steps of: responding to a request for allocation of RAM to a higher priority procedure by determining if RAM is available from the first portion and, if not, allocating RAM from the second portion to the higher priority procedure. The method enables allocation of RAM from the second portion to a lower priority procedure when available RAM in the first portion exceeds a first threshold level. The system continues the enablement until the available RAM in the first portion falls below a lower, second threshold level at which point, the allocation of memory in the second portion of RAM to the lower priority procedure is inhibited. The inhibition of allocation of RAM from the second portion to a lower priority procedure continues until the available RAM in the first portion again exceeds the first threshold level.
