Collaboration diagram for Digital Signal Processor Configuration:

The Digital Signal Processor (DSP) of dsPIC33C can be configured to support specific functions optimized for fixed-point arithmetic of a normalized number space as well as enhanced features such as accumulator and write-back saturation. As there is no other software instance using the DSP other than the power supply control loops, the DSP is configured at device start to save time during high frequency computations of the high-speed control loop.
