ABSTRACT:
A multifunction arithmetic logic circuit having comparison and numeric conversion circuitry, particularly adapted for use in graphics processing. The inventive architecture comprises a modular arithmetic logic unit in a pipelined architecture circuit. Functions performed are conversion of floating point numbers to fixed point numbers, and vise versa, arithmetic and logical operations, and numeric comparison operations. A visibility logic subcircuit is included for rapidly tracking numeric comparisons to indicate whether a graphics object is to be considered visible, partially visible, or invisible.
