package TMTEST is

-- The following is the ID of the semaphore used for timing operations.
--
SEMAPHORE_ID : RTEMS.ID;
--
-- The following variable is set to the execution time returned
-- by the timer.
--

--
-- INIT
--
-- DESCRIPTION:
--
-- This RTEMS task initializes the application.
--
procedure INIT (
ARGUMENT : in RTEMS.TASK_ARGUMENT
);
--
-- TEST_INIT
--
-- DESCRIPTION:
--
-- This subprogram performs test initialization. After completion
-- of test initialization, the timer is started and a preemptive
-- SEMAPHORE_RELEASE is performed.
--
procedure TEST_INIT (
ARGUMENT : in RTEMS.TASK_ARGUMENT
);
--
-- MIDDLE_TASKS
--
-- DESCRIPTION:
--
-- This RTEMS task performs a blocking SEMAPHORE_OBTAIN. Once
-- is obtains the semaphore unit and executes again, it performs
-- a preemptive SEMAPHORE_RELEASE.
--
procedure MIDDLE_TASKS (
ARGUMENT : in RTEMS.TASK_ARGUMENT
);
--
-- HIGH_TASK
--
-- DESCRIPTION:
--
-- This RTEMS task stops the timer and reports the execution
-- timer for a preemptive SEMAPHORE_RELEASE.
--
procedure HIGH_TASK (
ARGUMENT : in RTEMS.TASK_ARGUMENT
);
