The article considers the issues of solving the certain problem of special computing complexes and relates to the representation of information in Arithmetic-Logical Converters, built on the principles of color-light signal processing. Analysis of the construction of computing systems used in practice, incl. in the MIC, shows that, as a rule, the main types of processed information are: numbers (base - numbers), texts (base - letters), sounds (base - codecs), color and video images (base - light colors). And hereby, two main characteristic features of most of the listed types of information can be distinguished: they do not exist in nature in their pure form; their processing is ultimately carried out, as a rule, in digital form (we consider only digital signal processing systems). To improve the accuracy of processing all types of information, we abandoned the RGB color description system, since this system is characterized by the ambiguity of the RGB coordinate system, is device-dependent, gives an unclear idea of color based on the ratio of these signals, since exposure to one of these signals leads to a color change, which is difficult to predict and process correctly. Therefore, it is proposed to switch to displaying information in a colorimetric coordinate system with fixed wavelengths of the main color signals. This will simplify and speed up the processing of color images representing alphanumeric, audio and video information in an encoded form and ensure the stability of the optical nodes of an optical or hybrid processor, including when exposed to external destabilizing factors.
