56 * @defgroup Configuration RTEMS Configuration
57 *
58 * This module contains all RTEMS Configuration parameters.
59 *
60 * The model is to estimate the memory required for each configured item
61 * and sum those estimates.  The estimate can be too high or too low for
62 * a variety of reasons:
63 *
64 * Reasons estimate is too high:
65 *   + FP contexts (not all tasks are FP)
66 *
67 * Reasons estimate is too low:
68 *   + stacks greater than minimum size
69 *   + messages
70 *   + application must account for device driver resources
71 *   + application must account for add-on library resource requirements
72 *
73 * NOTE:  Eventually this may be able to take into account some of
74 *        the above.  This procedure has evolved from just enough to
75 *        support the RTEMS Test Suites into something that can be
76 *        used remarkably reliably by most applications.

750 *
751 * The following applies to the data space requirements
752 * of the Priority Scheduler.
753 *
754 * By reducing the number of priorities in a system,
755 * the amount of RAM required by RTEMS can be significantly
756 * reduced.  RTEMS allocates a Chain_Control structure per
757 * priority and this structure contains 3 pointers.  So
758 * the default is (256 * 12) = 3K on 32-bit architectures.
759 *
760 * This must be one less than a power of 2 between
761 * 4 and 256.  Valid values along with the application
762 * priority levels and memory saved when pointers are
763 * 32-bits in size are:
764 *
765 *   + 3,  2 application priorities, 3024 bytes saved
766 *   + 7, 5 application priorities, 2976 bytes saved
767 *   + 15, 13 application priorities, 2880 bytes saved
768 *   + 31, 29 application priorities, 2688 bytes saved
769 *   + 63, 61 application priorities, 2304 bytes saved
770 *   + 127, 125 application priorities, 1536 bytes saved
771 *   + 255, 253 application priorities, 0 bytes saved
772 *
773 * It is specified in terms of Classic API priority values.
