Epson Progression Product Support Bulletin page 8

In the Wingine implementation, video data is sent from the CPU via the
existing memory bus directly into VRAM and the CPU accesses VRAM
like system memory, at CPU speed. Video data then travels to the
Wingine graphics accelerator and on to the display. This simplified method
processes the data in fewer steps, resulting in greater video performance
and avoiding the bottlenecks and timing problems associated with ISA bus
and local bus technologies. Moreover, video performance is further
enhanced because VRAM is capable of sending and receiving data at the
same time. And when the CPU is upgraded with either an OverDrive
processor or a faster CPU card, Wingine performance also increases,
since the CPU sends video data directly into the VRAM, without any
intervening component bottlenecks
