The system level refers to the ICs and software that implements the decision making, the sensors, and the actuation mechanics for steering, engine control, and so forth.

Today, the decision-making at the system level generally employs special-purpose So Cs that combine multiple CPU cores with Graphics Processing Units (GPUs), Digital Signal Processors (DSPs), Field Programmable Gate Array (FPGAs), Video Processing Units (VPUs), Image Processing Units (ISPs), Neural Processing Units (NPUs), and other kinds of computational accelerators.

One of the important features of real-time systems is the critical nature of the software execution speed with reference to external events.Finally, the Tesla gets around the curve and the driver disengages the autopilot.The point of the video is that the actual state of AV technology is far behind what you might think from reading accounts in the press.In this respect V&V is a concept which is not to be built in the hardware system as, however, the case is reverse for the concept of reliability.On the other hand, an independent V&V effort can be implemented on a software so that quality can be built into the software by means of provisons that the features, with respect to the above-stated items, of V&V issues are favorably implemented in the life-cycle of real-time software development.
