4 * @brief Configuration Table Template that will be Instantiated
5 * by an Application
6 *
7 * This include file contains the configuration table template that will
8 * be instantiated by an application based on the setting of a number
9 * of macros.  The macros are documented in the Configuring a System
10 * chapter of the Classic API User's Guide
11 *
12 * The model is to estimate the memory required for each configured item
13 * and sum those estimates.  The estimate can be too high or too low for
14 * a variety of reasons:
15 *
16 * Reasons estimate is too high:
17 *   + FP contexts (not all tasks are FP)
18 *
19 * Reasons estimate is too low:
20 *   + stacks greater than minimum size
21 *   + messages
22 *   + application must account for device driver resources
23 *   + application must account for add-on library resource requirements
24 *
25 * NOTE:  Eventually this may be able to take into account some of
26 *        the above.  This procedure has evolved from just enough to
27 *        support the RTEMS Test Suites into something that can be
28 *        used remarkably reliably by most applications.

597 *
598 * By reducing the number of priorities in a system,
599 * the amount of RAM required by RTEMS can be significantly

603 *
604 * This must be one less than a power of 2 between
605 * 4 and 256.  Valid values along with the application
606 * priority levels and memory saved when pointers are
607 * 32-bits in size are:
608 *
609 *   + 3,  2 application priorities, 3024 bytes saved
610 *   + 7, 5 application priorities, 2976 bytes saved
611 *   + 15, 13 application priorities, 2880 bytes saved
