Quatro® 4300 SoC Processor
Description
The Quatro® line of SoCs is a family of highly integrated, programmable processors for printers, scanners and all-in-ones (AIOs). Each SoC embeds a high-performance ARM® CPU core for processing page description languages (PDLs) and a Quatro SIMD DSP core for print acceleration and copy/scan image processing.
With the Quatro family, developers can efficiently build cost-effective controllers for a wide range of products using a single firmware base. The Quatro 4300 series integrates an ARM9 CPU core (up to 350 MHz) and targets low-end applications:
- Inkjet printers and AIOs
- Monochrome laser/LED printers and AIOs up to 35 ppm
- Color laser/LED printers and AIOs up to 10 ppm
- Low-end document and photo scanners
Higher performance applications are covered by the Quatro 4500 series.
The Quatro programmable architecture enables developers to differentiate their products. By utilizing the Quatro SoC’s programmable cores, developers can implement unique features, image processing algorithms and mechanism control.

Product details
CSR provides OEMs with a reference design for a laser 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.
The programming environment for the Quatro family is based on the GNU tools, widely recognized as one of the best embedded development tool sets available. The programming environment includes tools for the Quatro DSP—C compiler, assembler, simulator, debugger, and libraries. CSR’s extensive library of optimized image processing algorithms makes developing image processing pipelines easy.
Inferno Firmware Platform
Inferno is CSR’s modular firmware platform for the Quatro family. With Inferno, a single firmware base covers the full range of Quatro SoCs. Inferno allows developers to choose either Embedded Linux or ThreadX for the underlying operating system.
Inferno is architected to provide the real-time processing capability required by high-performance printers, AIOs and scanners. The Quatro SOC’s flexRISC microcontroller cores are used to offload the most time critical tasks in printer and scanner mechanism control.
Inferno is designed to meet the varying needs of customers who want different degrees of customization. Inferno comes with a complete basic feature set for fast time-to-market. Customers who want extensive customizations can modify the supplied firmware components and/or add new firmware components. Most of the code is provided in source form.
Optimized IPS™ PDL Printing
Inferno and CSR’s IPS PDL interpreters take full advantage of each other. The IPS suite is integrated with Inferno to ensure fast time-to-market and optimized for Quatro to maximize PDL printing performance.
