1. A method of handling an interrupt in a rasterizer comprising: starting rasterization of a current primitive of a first process; determining if an interrupt is received during coarse rasterization of the current primitive; continuing rasterization of the current primitive until it is completed, if the interrupt is not received; saving the state of the rasterization of the current primitive of the first process, if the interrupt is received; servicing a second process corresponding to the interrupt, after the state of the rasterization of the current primitive of the first process is saved; restoring the saved state of the rasterization of the current primitive of the first process, after the second process is serviced; and continuing rasterization of the current primitive of the first process until rasterization is completed, after the state of the rasterization is restored.
