Description

Each Quatro^® 4305 & 4310 solution embeds a high-performance ARM9 CPU for processing page description languages (PDLs)and a Quatro SIMD DSP core for acceleration, providing OEMs with the compelling combination of integration and performance.

Laser Printers and MFPs

The market for laser printers and MFPs continues to grow rapidly. Driving this growth are lower prices, innovative features, and the proliferation of image-rich content from digital cameras, scanned documents, and the Web. Increasingly, all but the simplest entry level products now require sophisticated features, including color LCDs, and sophisticated image processing functions The 4305 and 4310 answers the need for these sophisticated feature requirements at very low cost. With full programmability and fast processing performance, the 4305 and 4310 provides OEMs with a flexible and cost-effective platform for implementing differentiated products.

Programmable Platform

The 4305 and 4310 is a highly integrated SOC solution for low cost laser printers that OEMs can program to implement the features and associated image processing required across a range of products. Because it is programmable, the 4305 and 4310 offers OEMs both significant time-to-market advantages and differentiation over conventional ASIC solutions.

By pairing the ARM CPU core with the Quatro DSP imaging core, the Quatro solution provides OEMs with a unique combination of high performance processing and easy-to-use programmability. The ARM CPU core, the established leader in embedded CPU cores, delivers high performance system and control processing with dense code size and a highly regarded software development tool suite.

The 4305 and 4310 Quatro DSP core builds on over 10 years of Zoran Quatro DSP technology. The 4-datapath parallel processing Single Instruction, Multiple Data (SIMD) architecture is specifically tailored for imaging applications, delivering unmatched performance.

The Quatro DSP offers up to 1.2 billion multiply-accumulates (MACs) per second at 300 MHz, allowing new imaging features to be quickly implemented without changing hardware, enabling rapid time-to-market and minimizing development expense.

Programming Environment

The programming environment for the 4305 and 4310 is based on the ARM RealView Developer Suite, widely recognized as one of the best embedded development tool sets available. To these proven ARM tools Zoran integrates a set of tools for programming the Quatro DSP-C compiler assembler, simulator, debugger, and libraries. Zoran’s extensive library of optimized image processing algorithms makes developing image processing pipelines easy.

Reference Design

To further shorten time-to-market, Zoran provides OEMs with a reference design for a color laser MFP. The reference design includes both a controller board and firmware. The reference controller board also serves as a development board that OEMs can use to prototype their own system code.
