Graphics Processor Register Definitions
6.4.2.5
GP Memory Offset 0Ch
Type
Reset Value
This register is used to specify the width and the height of the BLT in pixels. Note that operations that extend beyond the
bounds of the frame buffer space “wrap” into the other end of the frame buffer.
6.4.2.6
GP Memory Offset 0Ch
Type
Reset Value
This register is used to specify the length of the vector in pixels and the initial error term. Note that this is the same register
as GP_WID_HEIGHT, and that writing to one overwrites the other. They are separated for documentation purposes. As with
BLT operations, vectors that extend below or above the frame buffer space wrap to the other end of the frame buffer.
