Abstract: A system and method for converting a color uses an extended color space to convert a color from a first color space to a second color space. The extended color space is extended from the second color space. In other words, the extended color space has increased valid component ranges compared with the second color space to accommodate the conversion of any valid colors from the first color space. Subsequent operations on the converted color in the extended color space occur without the presence of conversion artifacts found in many conventional color space converters.

Abstract: A high performance computer graphics image computation system architecture is disclosed. The system architecture includes a computational processor ring which includes a plurality of closely coupled computational subsystems. The computational subsystems operate asynchronously and each is interconnected with two adjacent computational subsystems. The architecture of the processor ring allows rapid communication between the computational subsystems while avoiding a deadlock condition. The system architecture also includes a video processor ring wherein a plurality of video processors are synchronously linked together. A plurality of local communication paths couple the computational subsystems to the video processors. The video processor ring is able to move massive amounts of data, in the form of digital video signals, from various points within the system.
