Patent abstract
A new device executing an application on a new central processing unit (CPU), determines whether the application is for a legacy device having a legacy CPU. When the new device determines that the application is for the legacy device, it executes the application on the new CPU with selected available resources of the new device restricted to approximate or match a processing behavior of the legacy CPU, e.g., by reducing a usable portion of a return address stack of the new CPU and thereby reducing a number of calls and associated returns that can be tracked.
