The first is 400 MHz ARM11 CPU core with MMU and FPU, the second is dual 300 MHz quad-processor DSP cores, the third is 2400 MMACs DSP bandwidth, the fourth is USB 2.0 hi-speed device interface , the fifth is USB 2.0 hi-speed host interface, the sixth is USB 2.0 full-speed host interface, the seventh is 200 MHz 32-bit DDR2 SDRAM interface (DDR2-400), the eighth of 4320 is 32-bit 66 MHz PCI interface, the ninth is ethernet MAC, the tenth is scanner interface, the eleventh is programmable printer interface for multipass and tandem engines , the twelfth is memory card interface: compact flash and smart media, the thirteenth is complete reference design, the fourteenth is extensive image processing library.
      The 4320 can be described as followings. The 4320 leverages the ARM processor to power a color laser platform that processes zoran's PDL interpreter firmware, integrated print System (IPS).The 4320 is a highly integrated processor solution for desktop office printers and MFPs. OEMs can program the platform's features and associated image processing pipeline as required across a range of products spanning raster and PDL, print-only and MFP, monochrome and color. The 4320's full programmability offers OEMs significant time-to-market advantages over conventional ASIC solutions. The 4320 is based on Zoran's Quatro architecture. Quatro is ascalable, extensible architecture for constructing programmable processor solutions for imaging and printing devices. The programming environment for 4320 is based on the ARM realview development suite, widely recognized as one of the best embedded development tool sets available. To these proven ARM11 tools Zoran integrates a set of tools for programming the Quatro DSPC compiler assembler, linker, simulator, debugger, and libraries. Zoran's extensive library of optimized image processing algorithms makes developing image processing pipelines easy.
