CPU Board
The CPU board is based on the Digicolor2 circuit which performs in particular the function of mi-
croprocessor.
The executable code is stored in the flash memory.
This flash memory is divided in two zones:
1. A zone reserved for the storage of the code.
2. A zone reserved for the storage of the documents.
The code is loaded from this flash memory into SDRAM, and the microprocessor executes its in-
structions from the SDRAM.
Before printing, the documents to be printed are stored as bitmaps in SDRAM.
The SDRAM is also used as the working memory for the Digicolor2.
