As not all DSP routines are running at the same time and the integrated DSP provides 40
MIPS, additional DSP routines can be implemented by the user. For monitoring and
optimizing the DSP load, the programmer can use the Statistics Register.
Siemens also provides a PC based expert system for fast and correct DOC initialization,
refer to DOC Configurator, chapter 9.6.
