Benefits of technology

This technology allows for easy organization and maintenance by simplifying managing processes on an electronic device's flash chip (JAV). It eliminates accessing data repeatedly during storage or retrieving it from another location. By doing this, more efficient processing can occur with less effort compared to traditional methods like hard drives.

Problems solved by technology

This patented technical problem addressed by the present patents relates to improving Java Card's performance when managing large amounts of data stored within an operating system (OS). Specifically, current methods involve accessing storage locations repeatedly throughout the entire program or reloading applications with new ones without updating them afterwards. These techniques have resulted in slowdowns at least partially because they require complex operations involving both physical movement and software processing time.

Embodiment Construction

[0030] see figure 1 with figure 2 , the present invention includes object management area 1 and object data area. Object management area 1 is composed of read-only object management area 1.1 and dynamic object management area 1.2. The read-only object management area 1.1 is used to manage multiple read-only objects that will not change after the initialization is completed, and the dynamic object management area 1.2 is used to manage multiple dynamic objects that will be modified after the initialization is completed. An object's data is accessed through an object handle, which consists of an object ID and object properties. Objects include read-only objects and dynamic objects. The object handle is two bytes. The highest bit B15 indicates whether the object is in the read-only object management area 1.1 or in the dynamic object management area 1.2. B14~B0 indicate the block number, and the size of the block depends on the object The size of the management area and the req...

Abstract

A JAVA intelligent card structure and an object management method thereof relate to the intelligent card technical field; the structure comprises an object manage zone and an object data zone; the object mange zone comprises a read only object manage zone and a dynamic object manage zone; the read only object manage zone is used for managing unchangeable read only objects after the initialization is finished; the dynamic object manage zone is used for managing to-be modified dynamic objects after the initialization is finished; the object data can be accessed through an object handle; the object handle comprises an object ID and an object attribute; compared with the prior art, the novel structure and method need not to frequently access a nonvolatile memory, thus improving JAVA intelligent card execution efficiency.
