Backward compatibility with algorithmic matching, function disabling, or performance constraints

摘要

Issue backward compatibility for applications / titles designed for older versions of computer systems.A new device for executing the application on the new CPU determines whether the application is for legacy devices having legacy CPU.If the application is for legacy devicesNew CPUDisable the selected function of the new CPU that does not exist on Legacy CPUOr change the latency of the new CPU's instructions to fit or approximate the latency of the legacy CPUOr the new CPU's operation of one or more units to change the algorithm details to match the algorithm details of the legacy CPU corresponding unit operation or to approximate itRun the application.Diagram
