Dynamic sizing of memory caches

摘要

Disclosed are cache management apparatus and methods. A mobile device can include a global cache manager (GCM), a processor, and a storage medium. The GCM can manage a cache for an application of the mobile device. The storage medium can store instructions that, upon the processor's execution, cause the mobile device to perform functions. The functions can include: receiving an indication of a triggering event related to memory allocated for the application; the GCM responsively determining an amount of memory allocated to the application; the GCM determining whether a memory limit for the application is within a threshold amount of being exceeded by the amount of memory allocated to the application; and responsive to determining that the memory limit for the application is within the threshold amount of being exceeded, instructing the application to cease utilization of a portion of memory allocated to the cache.

1. A mobile device, comprising:
a global cache manager, wherein the global cache manager is configured to manage a cache for one or more applications of the mobile device, wherein the mobile device comprises a non-application space and an application space, wherein the non-application space is distinct from the application space, wherein the non-application space is configured to store an operating system of the mobile device, and wherein the global cache manager and the one or more applications are configured to execute while resident in the application space of the mobile device; a processor; and a computer-readable storage medium having instructions stored thereon that, upon execution of the instructions by the processor, cause the mobile device to perform functions comprising:
receiving, at the global cache manager, an indication of a triggering event related to memory allocated for an application of the one or more applications, wherein the global cache manager is distinct from the application;responsively determining, using the global cache manager, an amount of memory currently allocated to the application;determining, using the global cache manager, whether a memory limit for the application is within a threshold amount of being exceeded by the amount of memory currently allocated to the application; andresponsive to determining that the memory limit for the application is within the threshold amount of being exceeded, the global cache manager instructing the application to cease utilization of a portion of memory currently allocated to the cache.
