- * @defgroup CPUTimestamp Processor Dependent Timestamp Support
- *
- * This group assists in issues related to timestamp implementation.
- *
- * The port must choose exactly one of the following defines:
- * - #define CPU_TIMESTAMP_USE_STRUCT_TIMESPEC TRUE
- * - #define CPU_TIMESTAMP_USE_INT64 TRUE
- * - #define CPU_TIMESTAMP_USE_INT64_INLINE TRUE
- *
- * Performance of int64_t versus struct timespec
- * =============================================
- *
- * On PowerPC/psim, inlined int64_t saves ~50 instructions on each
- *   _Thread_Dispatch operation which results in a context switch.
- *   This works out to be about 10% faster dispatches and 7.5% faster
- *   blocking semaphore obtains.  The following numbers are in instructions
- *   and from tm02 and tm26.
- *
- *                        timespec  int64  inlined int64
- *   dispatch:              446      446      400
- *   blocking sem obtain:   627      626      581
- *
- * On SPARC/sis, inlined int64_t shows the same percentage gains.
- *   The following numbers are in microseconds and from tm02 and tm26.
- *
- *                        timespec  int64  inlined int64
- *   dispatch:               59       61       53
- *   blocking sem obtain:    98      100       92
- *
- * Inlining appears to have a tendency to increase the size of
- *   some executables.
- * Not inlining reduces the execution improvement but does not seem to
- *   be an improvement on the PowerPC and SPARC. The struct timespec
- *   and the executables with int64 not inlined are about the same size.
