Sony Interactive Entertainment as had yet another Backwards Compatibility patent go live. Today, a filing from 2017 has gone public and the creator is none other than Mr. Cenry.
This one talks about disabling a legacy CPU for a new CPU with “selected features of the new CPU that are not present on the legacy CPU”. Full description of the patent:
A new device executing an application on a new CPU determines whether the application is for a legacy device having a legacy CPU. When the application is for the legacy device, the new CPU executes the application with selected features of the new CPU that are not present on the legacy CPU disabled, or with a latency of instruction execution of the new CPUs altered to match or approximate a latency of the legacy CPU, or with algorithmic details of operation of one or more units of the new CPU altered to match or approximate algorithmic details of operation of corresponding units of the legacy CPU.
Could this potentially mean Backwards Compatibility for PS5? We shall find out soon enough!
