Method and product for synthesising print data and for providing the data to a printer

A product, in particular computer program product, for synthesizing M-bit print data and providing it to at least one printer, comprising:

• A. a raster graphics processor with at least one system-on-chip comprising a plurality of processors, which is designed such that object-based data entered into the raster graphics processor of at least one image in the form of a page description language are converted into N-bit pixel data of each color channel of a first target color space with a predetermined image resolution by providing the object-based data to some or all of the plurality of processors and processing them in parallel with the processors;
• B. a dithering computing unit which is designed to convert the N-bit pixel data of each color channel into M-bit print data of each color channel of a second target color space using at least one dithering algorithm and to store it in an output memory;
• C. an output unit designed to provide the M-bit print data to the printer;
• D. the at least one printer for printing at least one print medium;
• E. wherein each system-on-chip comprises a single-core or a multi-core main processor for delegating predetermined tasks, preferably converting the object-based data to N-pixel data, to the processors,
• characterized in that the system-on-chip is designed as a programmable system-on-chip and the processors are designed as single-instruction-multiple-data-capable or multiple-instruction-multiple-data-capable processors, each with at least one vector-based arithmetic logic unit, which vector-based arithmetic logic units are each configured, in such a way that when the object-based data is processed in parallel, several object-based data entering the respective arithmetic logic unit in parallel, each with a bit width of X bit using a predetermined one the processor's arithmetic operation set is converted into pixel data with a bit width of Y bit, which is larger than the bit width of X bit, the Y bit pixel data then being stored in a pixel memory in the form of a pixel matrix which consists of an integer number of N bit pixel data.
