DEFINITION

Classification: 712/216

DYNAMIC INSTRUCTION DEPENDENCY CHECKING, MONITORING, OR CONFLICT RESOLUTION:

(under the class definition) Subject matter including means or steps for on-the-fly testing of instructions and operands to assess conflicts related to data or functional unit availability (e.g., identifying dependencies, attempting to resolve dependencies, or both).

(1) Note. This subclass is directed to means and steps for controlling instruction issuing or executing which takes into account readiness of the instruction processing resource(s). Task resource management is classified elsewhere.

(2) Note. This subclass is also for dynamic hardware based dependency checking. Dependency checking performed by a compiler is classified elsewhere.

(3) Note. Reliability and availability of functional units include the determination of a fault condition and are classified elsewhere.

(4) Note. This subclass includes dealing with resource management problems within the instruction stream, generally at the ALU functional unit level. Resource management in a manufacturing environment is classified elsewhere.

(5) Note. This subclass deals with reserving use of functional units at the instruction level of a digital data processing system. Reservations for seat assignment for travel or entertainment are classified elsewhere.
