68 * The model is to estimate the memory required for each configured item
69 * and sum those estimates.  The estimate can be too high or too low for
70 * a variety of reasons:
71 *
72 * Reasons estimate is too high:
73 *   + FP contexts (not all tasks are FP)
74 *
75 * Reasons estimate is too low:
76 *   + stacks greater than minimum size
77 *   + messages
78 *   + application must account for device driver resources
79 *   + application must account for add-on library resource requirements
80 *
81 * NOTE:  Eventually this may be able to take into account some of
82 *        the above.  This procedure has evolved from just enough to
83 *        support the RTEMS Test Suites into something that can be
84 *        used remarkably reliably by most applications.

738 *
739 * The following applies to the data space requirements
740 * of the Priority Scheduler.
741 *
742 * By reducing the number of priorities in a system,
743 * the amount of RAM required by RTEMS can be significantly
744 * reduced.  RTEMS allocates a Chain_Control structure per
745 * priority and this structure contains 3 pointers.  So
746 * the default is (256 * 12) = 3K on 32-bit architectures.
747 *
748 * This must be one less than a power of 2 between
749 * 4 and 256.  Valid values along with the application
750 * priority levels and memory saved when pointers are
751 * 32-bits in size are:
752 *
753 *   + 3,  2 application priorities, 3024 bytes saved
754 *   + 7, 5 application priorities, 2976 bytes saved
755 *   + 15, 13 application priorities, 2880 bytes saved
756 *   + 31, 29 application priorities, 2688 bytes saved
757 *   + 63, 61 application priorities, 2304 bytes saved
758 *   + 127, 125 application priorities, 1536 bytes saved
759 *   + 255, 253 application priorities, 0 bytes saved
760 *
761 * It is specified in terms of Classic API priority values.
