#CHIPS: "Freescale ups ante with quad-core Qorivva"

Automotive microcontrollers are just as safety conscious as the Space Shuttle, since human lives are at risk, which is why Freescale adopted a similar strategy to have a completely redundant core whose results are compared with the main core at each time step, allowing errors to be corrected before they cause loss of life.

Quad-core Qorivva MPC5746M microcontroller features a redundant checker-core (brown at top) which performs critical calculations one-step behind main core to ensure errors are caught and corrected (click on image to enlarge).

Boosting the performance of its automotive microcontrollers—without increasing power consumption—is the aim of the new quad-core processor announced Tuesday (April 24) by Freescale Semiconductor Inc. at the 2012 Society of Automobile Engineers World Congress in Detroit.
