DSP processor - Language software

The DSP processor (Digital Signal Processor) is divided into two modules, application and language, which amongst other things handles the following:

• Voice activation
• Voice commands
• Certain parts of the Bluetooth function

New for the Tech 2 version 112.000 is that there is only one menu option for CU in SPS in Tech 2 (CU/PU). Other options are selected later in TIS 2000. This differs from earlier CU-AMPS, which had the "Application" and "Language" options in Tech 2.
