Method and system for scheduling the use of a computer system resource using a resource planner and a resource provider

A method for developing a real-time application program for performing a processing objective in a real-time manner, the method comprising the steps of:

• preparing a substantive portion of the real-time application program for performing the processing objective, the substantive portion specifying the use of a computer system resource;
• and
• adding to the substantive portion of the real-time application program calls to a real-time application programming interface for reserving and scheduling the use of at least a portion of the computer system resource, such that the added calls enable the real-time application program to perform its processing objective in a real-time manner.

A computer-readable medium containing data causing a computer system to perform a processing objective in a real-time manner by performing the steps of:

• executing steps for performing the processing objective, the executed steps specifying the use of a resource of the computer system;
• and
• calling a real-time application programming interface to reserve and schedule the use of at least a portion of the resource, such that the processing objective is performed in a real-time manner.

A computer memory containing a resource management data structure for use in managing the use of resources by real-time programs and non-real-time programs, the data structure comprising:

• information defining a resource planning state useable for issuing reservations to the real-time programs to use shares of at least some of the resources in response to requests submitted by the real-time programs;
• and
• information defining a scheduling state useable for scheduling the use of resources by the non-real-time programs and the real-time programs in accordance with issued reservations.
