7.3.1 Setup processing
The vertex data transformed by the geometry engine is transferred to the setup engine. CORAL has a
drawing interface that is compatible with the MB86290A. It operates parameters for various slope
calculations, etc., with the setup engine. When the obtained parameters are set in the drawing engine,
the final drawing processing starts.
7.4 L o g O u t p u t o f D e v i c e C o o r d i n a t e s
A function is provided to output device coordinates (DC) data obtained by view port conversion to local
memory (graphics memory).
7.4.1 Log output mode
Drawing & log output command
Log output of drawing coordinates (device coordinates) can be performed concurrently with primitive
drawing.
Log output can be controlled using the command with log output on/off attribute; log output is
performed only when the log output on attribute is specified.
Log output dedicated command
When the log output dedicated command is used, log output of the device coordinates can be
performed.
7.4.2 Log output destination address
The log output destination address is controlled by the device coordinates log pointer. Once set an
address, this pointer automatically increment an output address.
