This chapter provides information on the hardware
architecture of the Matrox Orion, as well as the features and
operating modes supported by the board.
The chapter is divided into three sections. The first section
describes the Matrox Orion hardware that is associated with
the acquisition of images, while the second section describes
the hardware related to the display of images. The third section
discusses the data interfaces, and how to transfer images from
on-board memory to Host memory and vice versa. For a
summary of the information given in this chapter and detailed
