A controller system includes a CPU module, one or more technology modules, and a backplane bus. The CPU module comprises a processor executing a control program. The technology modules include an artificial intelligence (AI) accelerator processor configured to (a) receive input data values related to one or more machine learning models, and (b) apply the machine learning models to the input data values to generate one or more output data values. The backplane bus connects the CPU module and the technology modules. The technology modules transfer the output data values to the processor over the backplane bus and the processor uses output data values during execution of the control program.
