I think this was quoted out of context. When he says "mechanical accuracy", he must be referring to a 60-tooth toothwheel attached to the crankshaft to measure angle position. eTPU has angle measuring support that increases the accuracy to less than a tenth of degree.

Sounds like a good MCU but statements like "accuracy limited to six degrees in current engines" is total BS and destroys credibility.

we did a support for a multicore PPC, open sourced. If interested, please check the ERIKA Enterprise website...

It seems that there is already an open-source RTOS supporting dualcore PPCs, http://erika.tuxfamily.org/wiki/index.php?title=Freescale_PPC_e200_(MPC_56xx)

Dual core seems promising. However, in engine control, the key factor is still ensuring timing requirements met.

Actually, it is also a trade off of power performance capability increase versus device consumption

eTPU might be considered as a coprocessor. It requires specific tools for programming Freescale has info about eTPU on its web site at bit.ly/pwsnK9 Freescale’s software tool chain regarding eTPU programming is on its web site here: bit.ly/oxYiUM

This should put some spark in the tired processing engines for automotive. I like the speed and the dual core approach. I wonder how flexible the eTPUs will be to program for non-engine related uses (PWM,..)?

This will really give a spare capacity for the auto electronic design engineers and this cpu will lead them to put some more auto diagnostic features in the automobiles.
