It can, but you have to understand that the AM335x processor is a general purpose applications processor. So when compared directly with specific purpose type processor such as the TI TM4C micro processor, it can be slower at some, or perhaps all real time tasks. However, something that perhaps you may not be aware of. The AM335X comes with two PRU's on die. These *P*rogrammable *R*eal-time *U*nit's can be used outside of Linux, and offers a small instruction set where many instructions are single cycle( 5ns ). In short, this on die real time controller is a simplified instruction set Cortex M3, that sits on the L3 interconnect bus of the main AM335x processor . . . So it can control just about anything, but some things are slower than single cycle access. Particularly, from what I understand, any interaction over the L3 interconnect will be slower than single cycle. But it's still fast and very deterministic.
