| 3 | * This include file has defines to represent the overhead associated |
---|
| 4 | * with calling a particular directive from C. These are used in the |
---|
| 5 | * Timing Test Suite to ignore the overhead required to pass arguments |
---|
| 6 | * to directives. On some CPUs and/or target boards, this overhead |
---|
| 7 | * is significant and makes it difficult to distinguish internal |
---|
| 8 | * RTEMS execution time from that used to call the directive. |
---|
| 9 | * This file should be updated after running the C overhead timing |
---|
| 10 | * test. Once this update has been performed, the RTEMS Time Test |
---|
| 11 | * Suite should be rebuilt to account for these overhead times in the |
---|
| 12 | * timing results. |
---|
| 13 | * |
---|
| 14 | * NOTE: If these are all zero, then the times reported include |
---|
| 15 | * all calling overhead including passing of arguments. |

| 31 | * Units are 100ns. |
---|
| 32 | * |
---|
| 33 | * These numbers are of questionable use, as they are developed by calling |
---|
| 34 | * the routine many times, thus getting its entry veneer into the (small) |
---|
| 35 | * cache on the 403GA. This in general is not true of the RTEMS timing |
---|
| 36 | * tests, which usually call a routine only once, thus having no cache loaded |
---|
| 37 | * advantage. |
---|
| 38 | * |
---|
| 39 | * Whether the directive times are useful after deducting the function call |
---|
| 40 | * overhead is also questionable. The user is more interested generally |
---|
| 41 | * in the total cost of a directive, not the cost if the procedure call |
---|
| 42 | * is inlined! (In general this is not true). |
