Another patent published by Sony has surfaced online, after a previous patent detailing processor ID spoofing hinted at backwards compatibility for the PlayStation 5. The new patentis titled "Simulation of legacy bus operation for backward compatibility" and lends further credence to theories that Sony's secret weapon for the PlayStation 5 is backwards compatibility.
The patent details how Sony might deal with bus interference and differences in operation when executing legacy applications on a new device. The patent goes on to suggest that Sony could emulate the bus operation that the legacy application was designed for with a new device -- for example, the PlayStation 5. What's more, the patent also mentions that Sony could use this method to augment bus performance and bandwidth.
