Hardware Description

1.2.1 Integrated Full Color MFP Controller (MFC2000)

The MFC2000 provides the majority of the electronics necessary to build a color scan and color inkjet printer

based MFP whose electronics are integrated into a one-chip solution including one CPU (ARM7TDMI) and two

DSPs (Countach Imaging DSP subsystem and P80 core).

Full printer and copier functionality is provided by the following:

• 1284 parallel port interface

• USB serial port interface

• Color scanner interface/controller

• Countach Imaging DSP subsystem for video/scan/compression process

• Flash memory controller

• SDRAM/DRAM controllers

• Resolution conversion logic

• Inkjet data formatter

• External inkjet printing

In addition, the MFC2000 performs facsimile control/monitoring, compression/decompression, and 33.6 Kbps Fax

Modem functions (P80 core). The MFC2000 interfaces with major MFP machine components like external

modems, SmartDAA, external Fax IA, motors, sensors, external video chip, and operator control panel. The

ARM7TDMI-embedded processor provides an external 48-MB direct memory access capability. An integrated

12-bit Pipeline ADC (PADC) and countach subsystem (DSP subsystem, combined with an advanced Conexant

proprietary color image processing algorithm, provides state of the art image processing performance on any type

of images, including text/half-tone and color images.

The full color MFP Engine provides the hardware and software necessary to develop a full-color Multifunctional

Peripheral including an architecture for color printing, color faxing, color scanning, video capturing, and color

copying. It also supports many of these operations concurrently.

1.2.1.1 Printing

The MFC2000 Controller supports color inkjet printing. Print speed throughput capabilities are inversely

proportional to resolution and also depend on the external printer interface. For host printing, the host sends the

image data with the print resolution; the MFC2000 performs no resolution conversion. If host printing and faxing

need to be performed for the same image, the printing image data must be sent to the MFP. The MFC2000

converts the printing image data to the faxing image data locally and then faxes it out. An external printer interface

chip is designed to support inkjet print mechanism/head subsystems. Different external printer interface chips can

be designed and used to support other inkjet mechanisms and heads according to customer requirements.

1.2.1.2 Faxing

Both host-based color faxing and standalone color faxing are supported in addition to monochrome faxing. Host-

based faxing can take place by using a Class One connection via the USB serial port or the P1284 parallel port.

For host faxing, the host sends the image data with the fax resolution; the MFC2000 performs no resolution

conversion. For standalone faxing, the resolution conversion is supported by the MFC2000. The standalone color

scan-to-fax function is supported using the advanced Conexant proprietary color image processing technology:

• Shading correction

• Gamma correction

• Pixel-based dark-level correction

• Color/monochrome image processing

• Color conversion

• JPEG

• Multi-level resolution conversion.
