  • Between R or A Family... ?
    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...
  • Is that possible for Cortex-R5's dual-core to handle interrupt during lock-step mode?
    As I know, Cortex-R5MP supports lock-step mode and every output from two cores will be compared in this mode. I'm curious about the handling of Interrupt Service Routine during the lock-step mode. ...
