Hi,
Can you give me a concrete example of an application requiring the cortex-R family (exept for the watch and the video-recording). Given the gap in price between processors, Except in the case of a large-scale purchase why not choose the cortex-A family ?
regards,
the R family was intended for high reliability embedded (like automotive, industrial), while the A device generally include a MMU and were intended for running operating systems (mostly linux based).
to get an idea what reliability means, if I remember right, TI has some R devices with dual cores, placed at 90 degrees, and with some internal comparators, able to detect when affected by unusual external conditions (like cosmic rays).
