A runtime-resource management method, system, and product for managing resources available to application components in a portable device. The method, system, and product provide for loading one or more new application components into a portable device only if maximum runtime resources required by the one or more new application components are available in the portable device assuming loaded application components within the device are using the maximum runtime resources reserved by the loaded application components, reserving maximum runtime resources required by application components when application components are loaded into the portable device, and running loaded application components using only the runtime resources reserved for the loaded application components.

Runtime-resource management

The invention provides a method for removing code (applications and data) from read-only memory, and compacting the remaining code in memory either as an application is deleted or when there is not sufficient room to hold a new application. One or more &ldquo;spare&rdquo; memory segments are reserved for use during compaction. Where the code for removal shares a memory segment with other code that is not to be removed, the other code is copied to a spare memory segment, and then swapped back to its original location. The code can then be compacted to remove the &ldquo;holes&rdquo; left by the erased code.
