Single integrated safety controller

The next level of integration involves using one of the processing cores inside the central compute or communication processor for safety channel 1 while partitioning the rest of the processor to perform the application including control, processing and/or communications. The 2nd safety channel operates on a separate controller (different piece of silicon) as shown in Figure 2.
