Real differences between Cortex-R and M

Hello, I'm doing some research about hard real-time systems. I would like to know what are the differences that make a Cortex-R more suitable for hard real-time tasks. I'm asking here because I have...
Can simulator approximate real-time?

I have developed some C51 software and it works fine in the simulator, the only problem is that the simulator goes far too fast! Strings that are only supposed to come out of the serial port once per...

Simulator code execution speed different to real life

Hi there, I am using the uVision 3 software simulator to do some profiling type testing. I can run the simulator and real hardware and get the same IO behavior. The hardware uses nearly every timer...
