SUMMARY

Motorola has made available a static library, LIBMOTO, which may improve performance of some PowerPC applications built using Microsoft Visual C++. Linking with LIBMOTO replaces the following C Runtime Functions: 
   * cos                    * pow
   * exp                    * sin
   * log                    * sqrt
   * log10                  * strcmp
   * memcpy                 * strlen
   * memmove                * strncmp
The memory and string functions have been hand-tuned in PowerPC assembly language for high performance. The math functions contain some tables and algorithms that are proprietary to Motorola. Applications that make heavy use of the above CRT functions may see an improvement in performance.

MORE INFORMATION

LIBMOTO was originally released as part of the Motorola C/C++ SDK. Motorola is making LIBMOTO available as a stand-alone product free of charge to encourage PowerPC development. LIBMOTO may be downloaded from Motorola's Website at:
