The Motorola MC68322 is a high-performance integrated printer processor, which combines an MC68000 compatible EC000 Core processor, a RISC graphics processor (RGP) and a print engine video controller (PVC) with numerous system integration features on a single integrated circuit. It is the first of Motorola's M68000 family designed specifically for laser printers. The MC68322 provides a unique solution for new designs as well as an excellent migration path for existing M68000-powered printers. Additionally, the new chip will find ready application to the inkjet printer and multifunction-peripheral (Fax/Modem/Printer) markets and other embedded control applications, which require very fast bit manipulations. The MC68322 provides outstanding performance at an extremely affordable price.
The Motorola MC68322 is a specialized integrated circuit designed specifically for laser printers. It combines an MC68000 compatible EC000 Core processor, a RISC Graphics Processor (RGP), and a Print Engine Video Controller (PVC) on a single chip to optimize system performance and reduce component count.
The device utilizes a unique dual bus architecture to eliminate contention between processing units, enabling parallel processing. It supports high-resolution printing up to 600 DPI at speeds of 8 pages per minute using memory reduction techniques like banding and run-length encoding.
