Sony’s Backwards Compatibility Patent that was Filed in 2017 got published today

Written by Admin

The Patent is about downclocking the CPU and matching the previous hardware for Backwards Compatibility, The Patent states that “An application runs at a first operating frequency if the application is designed for a current version of a system and runs at a second operating frequency if the application is designed for a prior version of the system that operates at a lower frequency than the first operating frequency. The second operating frequency may be higher than the operating frequency of the prior version of the system to account for differences in latency, throughput or other processing characteristics between the two systems. Software readable cycle counters are based on a spoof clock running at the operating frequency of the prior version of the system, rather than the true operating frequency. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims”. We are pretty sure this is for the PS4 backwards compatibility. Sony has also filed this kind of patent for the PS4 Pro Boost Mode before.

PS5 is indeed going to have backwards compatibility with the PS4, but we don’t know if the rumours that said it will be able to play every PlayStation game through backwards compatibility.

We can expect the PS4 games to have a higher resolution and FPS on the PS5 as it is going to be more powerful in every aspect.

What do you think? Please let us know in the comments below.

  • Man, I knew claiming all the included games with PS+ since launch would eventually pay off! Unfortunately, I did not keep my PS3 discs… so you win some, you lose some. Backward compatibility is a real game-changer in terms of keeping player base. One of the reasons it was so easy to transition from 360 to PS4, back when Microsoft was fumbling their initial messaging and before they had 360 backward compatibility, was that it was a completely fresh system. Hopefully, this will mean that next-gen systems will all share a common architecture and libraries won’t become obsolete in future. I guess I’m buying a PS5.
