Product Brief  
The PM-44ix is a high-performance, programmable digital signal  
processor (DSP) for applications such as low-cost multifunction  
peripherals (MFPs). Based on an advanced parallel processing  
architecture designed specifically for image processing, the  
PM-44ix delivers superior price/performance over conventional  
DSPs in similar applications. The PM-44ix provides MFP  
designers with all the flexibility advantages of a software-based  
image processing solution at the price/performance of fixed-  
function silicon.

Description  
High-Performance Imaging Platform  
The PM-44ix contains four symmetric parallel pipelined processors  
that together deliver 3,700 MIPS and 930 MMACS.  
Low-cost MFPs are advancing at an increasingly rapid rate. In  
addition to improved performance and lower price, new functions  
such as digital photo printing, color fax, Internet fax, and higher  
quality copying are making MFPs more compelling to consumers,  
and quickly making current models obsolete. To implement this  
growing list of functions with ever shorter time-to-market, MFP  
designers need a programmable, high-performance imaging platform.  
The PM-44ix is that platform.  
Advanced Memory Architecture  
The PM-44ix's advanced memory architecture boosts performance  
and lowers cost. The PM-44ix employs three different types of  
memory:  
• 2 Kbyte instruction memory  
• 64 Kbyte high-speed embedded SRAM  
• Up to 64 Mbytes of external SDRAM  
Advanced Parallel Architecture  
A single PM-44ix delivers up to 16 color inkjet or 30 monochrome  
laser copies per minute. The PM-44ix achieves its impressive  
performance by processing image data in parallel. The PM-44ix is  
based on Zoran's advanced DSP single instruction, multiple data  
(SIMD) parallel processing architecture. The DSP SIMD architecture  
takes advantage of the parallelism inherent in image data by  
processing columns of an image in parallel. Conventional DSPs,  
based on very long instruction word (VLIW) parallel processing  
architectures, attempt to take advantage of the parallelism hidden in  
sequential code. For image processing applications, the DSP SIMD  
architecture achieves a much higher degree of parallelism and, as a  
result, provides superior price/performance.  
Data is transferred between the memories using programmable DMA  
controllers.  
The PM-44ix's instruction memory ensures single-cycle instruction  
execution.  
The PM-44ix's high-speed embedded SRAM provides high  
bandwidth for memory-intensive image processing algorithms. The  
PM-44ix's processors operate directly on data stored in this memory.  
An integrated controller provides an interface to low-cost external  
SDRAM that can be used as a large buffer for input, output, or  
intermediate image data.
