>"The Alice 4 rasterizer is broken into two main parts: A software library linked with the C application program. The library implements the IrisGL API. It performs transformations, lighting, clipping, and retained mode (display lists). Its output is a list of commands (clear screen, draw triangle, swap buffers, etc.) that it writes to memory outside Linux's range. An FPGA configuration that reads these commands from SDRAM and executes them. For triangles it interpolates color (RGB) and depth (Z). The FPGA also scans out the image buffer to the LCD and performs other minor tasks."
