PM-44i
Programmable Imaging DSP
High-performance, low-cost peripheral imaging solution · UNMATCHED PRICE/PERFORMANCE Third-generation SIMD parallel processing architecture · FLEXIBLE PLATFORM Software development kit that enables OEMs to quickly add features and deploy proprietary intellectual property · FAST TIME-TO-MARKET Complete suite of customizable software image pipelines for MFPs · SUPERIOR IMAGE QUALITY Advanced image processing algorithms · COST-EFFECTIVE SOLUTION Embedded SRAM and small package ideal for highvolume color inkjet and monochrome laser MFPs MONOCHROME LASER MFP SOLUTION Image processing represents a key challenge in developing a low-cost MFP. The PM-44i is the ideal platform for implementing the complex image processing required to achieve highquality copying, scanning, and faxing on inexpensive scanner and printer components. A single PM-44i delivers up to 20 monochrome laser copies per minute. COLOR INKJET MFP SOLUTION With the PM-44i, OEMs can quickly implement their own image pipelines or use Oak Technology's image pipelines-- CopyFusionTM, ScanFusionTM, and FaxFusionTM. Utilizing proprietary algorithms, CopyFusion, FaxFusion, and ScanFusion deliver superior image quality, improved compression ratios, and faster inkjet printing. A single PM-44i delivers up to 10 color inkjet copies per minute. The PM-44i is that platform. The PM-44i provides the price/performance of a custom ASIC with all the time-tomarket advantages of a programmable DSP. Based on a single instruction, multiple data-path (SIMD) architecture designed specifically for high-throughput image processing, the PM-44i succeeds where conventional DSPs fail. The programmable PM-44i enables MFP designers to quickly implement their image processing algorithms and pipelines. For OEMs who want a total image processing solution, not just a platform, Oak Technology provides a complete suite of customizable image pipelines available as either source or object code. HIGH-PERFORMANCE IMAGING PLATFORM The low-cost MFP market is moving forward at an increasingly rapid pace. New features such as high quality copying, color fax, and Internet fax are quickly making current models obsolete. Delivering these new features with ever shorter time-to-market requires a high-performance, programmable imaging platform. tomizable image processing solution for low-cost MFPs. The PM-44iTM is a high-performance, programmable imaging digital signal processor (DSP) designed specifically for image processing in low-cost multi-function peripherals (MFPs). The PM-44i provides superior price/performance over conventional DSPs and greater flexibility over custom ASICs. Combined with Oak Technology's Fusion-series image pipelines, the PM-44i delivers a complete, cus-

THE OAK TECHNOLOGYTM iDSP FAMILY
TM
The PM-44i is part of the Oak Technology iDSP Family of high-speed imaging DSPs. Our industry-leading iDSP products--PM-44i and PM-48TM--are the only DSPs designed specifically for imaging applications in digital office equipment. Oak Technology iDSPs leverage today's most advanced technologies--including programmable operation-- to deliver the industry's highest performance and design flexibility, at the lowest possible cost. Typical color and monochrome applications include: high-speed copiers, fax machines, scanners, printers, multifunction peripherals, digital cameras, and raster image processors (RIPs).
A SUPERIOR ALTERNATIVE The PM-44i offers important advantages over other chip alternatives: · Conventional DSPs--The PM-44i provides much higher imaging performance at much lower costs than other DSPs. · FPGAs--The PM-44i offers much lower costs, higher performance, and a simpler code-based development process. · Custom ASICs--The PM-44i offers the time-to-market and low-cost advantages of a software-based solution. Its programmable design simplifies algorithm changes, reduces time-to-market by significantly reducing development time, and enables product upgrades and scalable architectures for entire product families. SINGLE PM-44i APPLICATION RUNNING MULTIPLE PIPELINES
MEMORY STRUCTURE The PM-44i is designed to access three different types of memory: instruction memory; embedded memory; and expansion memory. The 2KB instruction memory provides single cycle access times for the most commonly executed instructions. The PM-44i's embedded 64 KB high-speed SRAM is used for image data storage and secondary instruction storage. The PM-44i data paths operate on image data that is stored in this buffer. Instructions may be stored in the embedded memory and either executed in place, or transferred to the instruction memory for performance improvements. The PM-44i also has an internal SDRAM controller that supports up to 32 MB of low-cost external SDRAM for use as expansion memory, or as an input/output line buffer for storing image data. Data is transferred between the expansion memory and the embedded memory by internal DMA controllers. DESIGN CONSIDERATIONS The PM-44i can be easily integrated into a variety of systems.
