I concur. It's simply called riding the process technology wave...

Yalanand, see my comment above. While implementations vary, advanced timing and control of fuel spark and combustion can significantly reduce fuel and emissions. Engines have become more and more complex (even in emerging markets) in order to meet government emission standards, which has led customers to use 32bit MCU's over 16bit MCU's since 16bit MCU performance could not rival the scalabity and performance advantages 32bit MCU's offer.

While there are still some ECU's in emerging markets using a 16bit MCU, most have already or beginning to convert to 32bit MCU's. Moving from 16bit MCUs to low-end 32bit MCUs like MPC563xM can offer a 5-10x increase in performance throughput at similar costs since they begin to converge at small geometries. Combining performance increases with enhanced peripherals like signal processing, FPU, eTPU timers and decimation filters can filter and detect knock signals with more precision and remove external ASICs. Estimates indicate that precise spark timing can improve fuel efficiency and conservatively reduce emissions by more than 10%.

if 16 bit MCU can handle the process then what is the need of 32 bit MCU , i don't think it will increase the speed of operation..... speed of the processing time depends on the protocol used for communicating with the different parts of vehicle like CAN, LIN, FlexRay etc.

I'm guessing that the real reason for moving to 32 bit processors is that they are now readily available at a competitive price and easily interface with other components. Sticking with older technology eventually starts costing more overall. Marketing then makes an announcement to boast about the change to gain publicity.

Does the automotive require so much of electronics to improve the efficiency. The response time of the engines is always limited considering the mechanical parts involved.

I'm usually very skeptical about announcements like this on EETimes but I actually have hands on experience with S12XE microcontrollers and I have to say they are a piece of crap. Going 32bit doesnt just mean greater range for computations, but also a cleaner memory map without the paging hell (for apps bigger than 64k) and quite probably a higher performance per MHz. I can tell you by experience that higher complexity algorithms (like LQ controller) along with the regular safety management and diagnostic features easily eat up the performance budget of the S12XE. Going for the MPC is a good move from Chery, I think the whole automotive segment would benefit from forgetting legacy architectures like the 16bit S12X family.

eewiz, the freescale website says that the faster chip can process more complex algorithims. I would guess that this could been better learning, solenoid control etc.
