• 60 MHz clock for video memory

• fast linear addressing with full software relocation

• green power saving features

• playback acceleration, continuous interpolation on X, continuous interpo-

lation on Y

• DDC 2B compliant.

Standard and Enhanced Video Graphics Array (VGA) modes are available.

Hardware acceleration of graphical user interface (GUI) operations is

provided, and acceleration for 8, 16 and 32-bit pixel depths.

The table, on the following page, details the standard VGA modes which are

currently implemented in the video BIOS. These modes are supported by

standard BIOS functions. The video BIOS (which is mapped contiguously in

the address range C0000h to C7FFFh) contains all the routines required to

configure and access the graphics subsystem.
