Abstract (en)
[origin: WO2004100090A1] The invention relates to a method for the memory management in the execution of a program (30) by means of a portable data carrier (10) that comprises a first and a second memory area (34, 36) for storing objects (38, 40, 44) generated during program execution. An object (38, 40, 44) is first at least partially created in the second memory area (36). If during further program execution a persistent reference (42) to the object (38, 40, 44) is generated, the object is transferred to the first memory area (34). According to the method for converting a source program (80) to an executable program (40), at the time of compilation, it is checked whether a persistent reference (42) to an object (38, 40, 44) to be newly created is generated. Depending on the result of this check-up, the program code is generated which creates the object (38, 40, 44) either in the first or at least partially in the second memory area (34, 36). The invention provides a means for memory management in a portable data carrier (10) which improves the utilization of an efficiently writable memory area.
