for the computing stuff I can imagine dedicated hardware but not for ram. Remember how small PS4 is, that would be a *lot* of stuff to be implemented on the board. I am looking forward on disassemblys of PS4. Remember the xbone-board? I really liked it :D

Sony already said no resource from the main CPU, GPU and RAM are used to the video recording feature.

And there is a theory by a "unknown" developer.

"I was talking to a third party developer recently who was impressed that on PS4 the recording feature doesn't use any main CPU/GPU/Memory resources. He theorised that it is done on a completely separate chip that taps into the output stream between the memory and HDMI and records the last 15 minutes of footage onto some stacked RAM (a method Sony already use for PS Vita)."

Nice if true but this would make a quite big chip. Even if it's an ARM it still needs quite some storage. And cooling. Anyway I want to see the mainboard!
