ABSTRACT:
A program execution and operation right management system capable of providing flexible and sufficient protection uniformly even for the thread operation instructions among the threads sharing the same virtual address space and/or for individual memory region. In the system, operation right data indicating which thread can be operated by which thread among a plurality of threads are stored, and whether a thread operation with respect to one thread requested by another thread among a plurality of threads is allowed by the operation right data is judged. Then, the processor is allowed to carry out said thread operation with respect to that one thread by that another thread only when it is judged that said thread operation is allowed by the operation right data.
