Two-level pipelined systolic array graphics engine

A silicon implementation of a two-level pipelined SAG (systolic array graphics) engine supporting an advanced instructions set is reported. The advantage of the two-level pipelining is that it can provide a complex functionality at high pixel rates, which is difficult to achieve by other means using less silicon area. As computer graphics users have a great desire for high image quality, high interaction speed and high resolution, it is expected that two-level pipelined SAG engines will be a breakthrough for real-time computer graphics
