Quatro® 4500 SoC Processor

For Printers

Benefits

• Family of SoCs that cover broad product range with a single firmware base
• Modular firmware platform
• Programmable architecture for implementing unique features and algorithms
• Industry’s only controller solution with optimized PDL interpreters

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. A key performance advantages is IPS’s multicore concurrent rendering, which utilized the Quatro 4500’s second CPU core (in dual-core versions) to achieve faster processing.
