-board was used to measure elapsed time with one-half microsecond
-resolution. All sources of hardware interrupts are disabled,
-although the interrupt level of the i960CA allows all interrupts.
-
-The maximum interrupt disable period was measured by
-summing the number of CPU cycles required by each assembly
-language instruction executed while interrupts were disabled.
-Zero wait state memory was assumed. The total CPU cycles
-executed with interrupts disabled, including the instructions to
-disable and enable interrupts, was divided by 33 to simulate a
-i960CA executing at 33 Mhz with zero wait states.

-
-The maximum period with interrupts disabled within
-RTEMS is less than
-RTEMS_MAXIMUM_DISABLE_PERIOD microseconds including the instructions
-which disable and re-enable interrupts. The time required for
-the i960CA to generate an interrupt using the sysctl
-instruction, vectoring to an interrupt handler, and for the
-RTEMS entry overhead before invoking the user's interrupt
-handler are a total of RTEMS_INTR_ENTRY_RETURNS_TO_PREEMPTING_TASK
-microseconds. These combine to yield
-a worst case interrupt latency of less than
-RTEMS_MAXIMUM_DISABLE_PERIOD + RTEMS_INTR_ENTRY_RETURNS_TO_PREEMPTING_TASK
-microseconds. [NOTE: The maximum period with interrupts
-disabled within RTEMS was last calculated for Release
-RTEMS_RELEASE_FOR_MAXIMUM_DISABLE_PERIOD.]
-
-It should be noted again that the maximum period with
-interrupts disabled within RTEMS is hand-timed. The interrupt
-vector and entry overhead time was generated on the Cyclone
-CVME961 benchmark platform using the sysctl instruction as the
-interrupt source.

-@section Context Switch
-
-The RTEMS processor context switch time is RTEMS_NO_FP_CONTEXTS
-microseconds on the Cyclone CVME961 benchmark platform. This
-time represents the raw context switch time with no user
-extensions configured. Additional execution time is required
-when a TSWITCH user extension is configured. The use of the
-TSWITCH extension is application dependent. Thus, its execution
-time is not considered part of the base context switch time.
-
-The CVME961 has no hardware floating point capability
-and floating point tasks are not supported.
-
-The following table summarizes the context switch
-times for the CVME961 benchmark platform:
