How much of the work the host CPU does depends on how the display driver is written. There is a great deal of opportunity in the driver to offload work to a TMS34010 (although I thought the boards mentioned used TMS34020s... I could well be wrong, though). One of the best examples is block transfers, or BLTs, which happen every time you move a window. Another is pattern fills, which happen all the time. The list goes on and on... -- Jim Seidman (Drax), the accidental engineer.
