Appeal No. 96-3085
Application 08/274,655
been cancelled .2
The disclosed invention relates to a method and apparatus
for counting and monitoring processor execution cycles
associated with a specific task running concurrently with
other tasks in a hard real-time, multi-tasking microprocessor
such as a single processor. Such a processor runs multiple
tasks by dividing its execution cycles up among the specific
tasks. The invention provides that each task has a specific
processor cycle count allocated to it initially. A counter is
loaded with this allocated count initially. The method and
apparatus of the invention decrement a counter for a specific
task only when an execution cycle is allocated to perform that
specific task. When a specific task reaches its allocation,
an appropriate cycle counter interrupt is generated.
Representative claim 1 is reproduced as follows:
1. In a multi-tasking program execution system, a method
of monitoring task overrun conditions, the method comprising
the steps of:
counting only processor execution cycles associated with a
specific task occurring while said specific task is executed,
said specific task being executed together with one or more
