I would claim that while a single logical frame is easy to simulate on a digital computer, creating and balancing multiple, not-necessarily consistent frames is very difficult and requires as much computer activity or brain activity as the also difficult activities of raw input processing.
One might argue that neural system began as very different systems from digital computers but the evolution of the large human has allowed them emulate discreet, including a computer's digital logic while still doing the balancing of multitudes of environmental constraints which neural system have excelled at for millions of years. And letting "us" conceive-of and to even build computers perfecting this discreet logic. Pretty amazing.
