Why Cortex-R series is real time oriented ?

Hi Forum, Why Cortex-R series is real time oriented than other ISA(ARM/others) ? Is there a list of all the points and comparison with ARM Cortex-A ? Why we can not make Cortex-A to suite for real time...
Loop unrolling on Cortex-M3 vs. Cortex-M0

In the DSP lib files like arm_conv_f32, arm_fir_f32, the algorithm implementation in Cortex-M3/M4 and in Cortex-M0 is different. i.e., loop unrolling is used in M3/M4 and it is not used in M0. Pls tell...
Interruptible Instructions on Cortex-M4

The ARM Cortex-M4 Processor Technical Reference Manual states: To minimize interrupt latency, the processor abandons any divide instruction to take any pending interrupt. On return from the interrupt...
about tail chaning of Cortex-M0

Hello. I'm studying about the tail chaining of Cortex-M0. Is it same as Cortex-M3 or M4? Best regards.
"Dormant Mode" for Cortex M3/M4

Hi, We are interested in minimizing startup time from deep sleep mode. Some of the older ARM cores implement a dormant mode whereby the CPU core context (state) is written to RAM prior powering it down...
