ABSTRACT
<p>RISC (reduced-instruction-set-computer) CPU design concepts are used as the basis for a more general design philosophy applicable to graphics. The 3D graphics subsystem for the Apollo DN10000 is based on applying a RISC philosophy to the rendering problem. All structure-walking and floating-point computations are handled in the general-purpose CPU(s), and a simple, fast-cycle-time drawing engine synthesizes pixels and writes them into the bitmap. In the control and pixel-addressing logic, RISC ideas are applied directly and effectively; in color synthesis, however, they did not prove as useful. Several RISC concepts were ultimately fundamental to achieving design simplifications and allowed a better utilization of VLSI CMOS technology.</p>
