The system and methods allow for emulation of random hardware failure of an internal embedded memory array of an integrated circuit device. In view of this, input data which is dependent on a color space of an input device is converted by the conversion LUT 11 to color space data which is independent of any devices, based on a viewing condition at the time of viewing an input original. As the first and second sets of data streams propagate along the first and second router matrix cards, respectively, one or more health bits are set whenever an error or other type of fault condition is detected.
