1. A method of handling an interrupt in a rasterizer comprising: starting rasterization of a current primitive of a first process to determine which pixels of a display screen are related to the current primitive; determining, during coarse rasterization of the current primitive, if an interrupt is received; 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 after the coarse rasterization of a given tile of the current primitive is completed, if the interrupt is received during coarse rasterization of the current primitive; 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 from the restored state of the rasterization of the current primitive until rasterization of the current primitive is completed.
