SCEE's UK managing director Fergal Gara said that the handheld system will become a "PS4 in your pocket" thanks to this technology.
"The intention is that the vast majority of PS4 games will be playable on PlayStation Vita. I'm not the best guy to ask how easy that is, but my understanding is that it's pretty damn easy," Gara told Digital Spy.
"Maybe some games where it's a little awkward to execute on PlayStation Vita, but that'll more be because of additional controls, say for camera functionality on PS4 that might transfer across neatly.
"But my understanding is, if you're using the standard controls of the analogue sticks and buttons, etc, then that'll transfer across very neatly and very easily."
He added: "For me, from what I took out of that whole message was, we used to say PlayStation Vita is a PS3 in your pocket, well now we can very confidently say it's a PS4 in your pocket. So that is a great, great, great boost for PlayStation Vita."
Revealed earlier this week, the PS4 has been compared to a "supercharged PC". It features an x86 CPU, enhanced PC GPU and 8GB RAM.
New first-party games include Killzone Shadow Fall, Knack and Infamous: Second Son.
Sony has since opened official websites for the PS4, which contain trailers, images, specifications and more.
