Overview

Based on Zoran’s advanced Quatro architecture featuring an ARM9 RISC CPU and Zoran’s Quatro SIMD DSP, the 4301 and 4302 provide OEMs with a flexible and cost effective platform for implementing AIO and printer controllers with a range of features and performance.

The 4301 and 4302 build upon Zoran’s Quatro 4201 and 4202 SOCs, with more processing power and connectivity enhancements. The 4301 and 4302 are ideal for AIOs and photo printers with advanced features such as wireless and Ethernet connectivity, output to a TV and a connection to IDE hard disk.

Print Appliances

The market for print appliances, including AIOs and direct-connect photo printers 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, sophisticated photo processing functions and expanded wireless connectivity.

The 4301 and 4302 answer the need for these sophisticated feature requirements at very low-cost. With full programmability and fast processing performance, the 4301 and 4302 provide OEMs with a flexible and cost effective platform for implementing differentiated products.

Programmable Platform

The 4301 and 4302 are highly integrated SOC solutions for appliance printers that OEMs can program to implement the features and associated image processing required across a range of products.

Because they are programmable, the 4301 and 4302 offer OEMs both signifi cant time-to-market advantages and differentiation over conventional ASIC solutions.

Quatro Architecture

The 4301 and 4302 are based on Zoran’s Quatro architecture. Quatro is a scalable, extensible platform for constructing programmable SOC solutions in imaging and printing device.

At the heart of the Quatro architecture are four key elements:

• ARM 32-bit RISC CPU core
• Quatro 4-datapath SIMD DSP core
• Industry-standard internal bus
• Easy-to-use C-based programming environment Quatro^® Architecture
   
  By pairing the ARM CPU core with the Quatro DSP 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 Quatro DSP core in the 4301 and 4302 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 1.4 billion multiply-accumulates (MACs) per second at 350 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 4301 and 4302 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. Using the ARM CPU and Quatro DSP simulators, an OEM’s complete system—both system functions and image processing pipelines—can be fully developed and simulated on a PC.

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 an inkjet AIO. 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.
