Preliminary
3.8
The signal processing capabilities described in this chapter are realized by an Enhanced
Digital Signal Processor (EDSP) except for DTMF generation. Each function can be
individually enabled or disabled for each DuSLIC channel. Therefore power
consumption can be reduced according to the needs of the application. For the MIPS
requirements of the different EDSP algorithms see
