The features of the MPC8308 make it suitable for a wide variety of printer and network communication
applications as described in this section.
1.1 Low-End Printer CPU
Figure 1 illustrates how the MPC8308 can interface with the main ASIC on a low-end printer application.

In this application, the device interfaces to the main ASIC through the high-bandwidth PCI-Express bus.
Low-end multi-function printers (MFPs) are able to share the same platform simply by adding a
scanner/fax engine. The processor provides various network interfaces that are used to access the printer.
Image data coming through the scanner or fax interface is sent to the main ASIC, which processes the
image by implementing algorithms for image compression/decompression and rendering. The image data
is then processed in the FPU in the CPU core at high speeds and sent to the printer engine. Likewise, image
data or text data that are interfaced at the Ethernet interface on the processor are also manipulated at the
main ASIC and CPU and sent to the printer engine.
Recent MFP systems require higher processor performance in order to manipulate large, high-quality
images at high speeds. Required networking interfaces including USB, PCI Express, eSHDC, and Gigabit
Ethernet are integrated on the MPC8308. As a result, an MFP application can be developed by combining
the MPC8308 with the main ASIC (graphic processing ASIC) at a lower cost .
