摘要： Memory management by garbage collection involves a memory area that is allocated in a computer. Data is created in the memory area in accordance with a program executed by a processor of the computer, and it is checked whether or not data necessary to execute the program exists in the memory area to be released, in response to an explicit instruction to release the memory area. As a result of the check, if data necessary to execute the program does not exist in the memory area, the memory area is released. As a result of the check, if data necessary to execute the program exists in the memory area, the data is moved to a memory area different from the memory area to be released.

摘要： With regard to a plurality of data stored in a memory, relationship of data is grasped twice after a time interval therebetween. Next, increased data C1, E2, E3 which are not present in data of a first time are extracted from data of a second time, and weights “1”, “2”, “2” in accordance with data sizes are attached to the increased data. Next, the weights are successively propagated from a lower order data of a destination of reference to a higher order data of a source of reference successively. When there are a plurality of lower order data E2, E3 for a higher order D0, a weight constituted by adding the weights “2”, “2” of the plurality of lower data E2, E3 is made to be a weight “4” of the higher order data D0, and the weights of the respective data represent leak scores which causes memory leak.

摘要： For a program that runs on a microprocessor having a cache memory and an on-chip memory embedded therein with a capability of specifying and assigning embedded memory capacities, memory capacities to be allocated to the cache memory and the on-chip memory are determined according to memory sizes required for a set of referent data in the program, and a code is generated based on the memory capacities determined. The program may be divided by extracting at least one phase each comprised of a loop in the program and a set of referent data referred to in each phase, so that the memory capacities are determined according to the memory sizes required for the set of referent data divided.

摘要： A pointer field compression/expansion method is provided for a computer system having a data structure reference function using a pointer. The pointers in data structure which a program refers to are classified into pointers to be frequently referred to and those not to be frequently referred to. The pointers not to be frequently referred to are determined as targets of compression and expansion to thereby reduce and suppress the overhead required for the pointer compression and expansion. Information indicating whether or not a pointer in data structure is a compression target is provided separately or such identifying information is embedded into in the pointer whereby the compressed or uncompressed format of the pointer can be dynamically determined.

摘要： Under program execution environment, a file size of a heap dump is reduced which is acquired so as to detect memory leaks, and so as to investigate occurrence causes of the memory leaks. In order to provide a memory leak investigating means which can be used even in a large-scaled system, the below-mentioned heap dump acquiring method is provided: When a heap dump is acquired, only such an object within objects stored in a heap memory is outputted which is adapted to the following conditions: That is, in a condition (1), an object exists among objects which are newly produced within a designated time period, and in another condition (2), an object is present on a reference path defined from a root set to the object which satisfies the above-explained condition (1).

摘要： A nested-loop data prefetching method in which a program is converted so that prefetching is performed effectively even in nested loops in which the loop length of the innermost loops is short and the loop length of the outer loops is long. In this method, first a prefetch target loop is selected from the innermost loops in the nested loops. The selected loop is then split into a front half loop and a rear half loop by application of index set splitting. Further, an instruction to prefetch data used by the selected loop per se is inserted into the front half loop whereas an instruction to prefetch data used in the next prefetch target loop is inserted into the rear half loop.
