System for emulating graphics operations
View Patent ↗Disclosed is a system for producing images including emulation techniques. The system provides for emulation of graphics processing resources such that a central processing unit may provide graphics support. Disclosed embodiments include emulation of selected graphics calls as well as emulation of a programmable graphics processor for compatibility with systems having no compatible GPU.
1. A method of applying two effects to an image, the method comprising the steps of
using a first microprocessor to apply a first effect to a first frame of said image, said first microprocessor applying said first effect while emulating a second microprocessor;
using said second microprocessor to apply a second effect to said first-effected frame, applying said first effect to a next frame by said first microprocessor approximately during the time that said second microprocessor is applying said second effect to said first-effected frame.
2. The method of claim 1 wherein the first microprocessor is a CPU and the second microprocessor is a GPU.
3. The method of claim 1 where emulation is effected through a virtual machine.
4. The method of claim 1 wherein emulation is effected through translating a GPU program to a CPU program.
5. A computer-readable medium having computer executable instructions for performing the method recited in claim 1 .
