Acquisition method for ownership of multiprocessor system resources
专利汇可以提供Acquisition method for ownership of multiprocessor system resources专利检索，专利查询，专利分析的服务。并且PURPOSE: To keep the balance between a peripheral device and a processor by performing the input/output request processing with preference for an input/ output task having a running level higher than an application task.
CONSTITUTION: A main storage 3 includes a bus 4 which connects the processors 1 and 2 to the storage 3 and stores the exclusive resources 13 and 14, a resources acquring means 5 which acquires the resources 13 and 14 via the spin lock control, a resources release means 6 which releases the acquires resources, a task running level setting means 7 which sets the task running levels and allocates each task to its corresponding running level, and a resources processing running level transition means 8 which allocates the acquired tasks to each running level after the resources 13 and 14 are acquired via the spin lock control and then the task running levels are set for execution of the processing to those resources. Then a spin state is secured at a lower task running level even though a task 13 is set in a spin state by the processor 2 in a spin lock state. Therefore an input/output task having a higher running level than the task 13 receives an external interruption and processes an input/ output request with preference.
