Marvell PXA320 Processor Series
Cost-Effective, Scalable Performance up to 806 MHz for Power-Efficient, High-End
Multimedia Handsets, Embedded Solutions, and Enterprise-Class Devices
PRODUCT OVERVIEW
Leading the Marvell® PXA3xx processor family, the PXA320 processor, with scalable performance to 806 MHz, plus additional
industry-leading processing features, enables outstanding compute and video performance for high-end, multimedia cell
phones and PDAs, industrial embedded solutions, and enterprise-class devices. Built on a low-power 90 nanometer (nm)
process technology, and with the ability to dynamically scale voltage and frequency on demand, the PXA320 supports
today’s stringent requirements for longer battery life.
KEY FEATURES AND PLATFORM BENEFITS
The PXA320 processor integrates the following features:
• Scalable, general-purpose processing up to 806 MHz, a 256 KB L2 cache, and a 32-bit DDR memory interface for richer
end-user applications, such as browsing rich Web2.0 content or streaming video. Extended headroom allows for execution
of multiple applications at the same time, which is a key requirement for today’s wireless client devices with advanced
capabilities.
• Marvell® Scalable Power Manager technology for MIPS/mW power efficiency, delivering long battery life and enabling
consumers to spend more time enjoying the rich features their devices and service providers offer.
• Intel® Wireless MMX™ 2 technology, a 2D graphics accelerator, and a 768 KB frame buffer designed to support VGA
resolution streaming video enhance the user’s experience of popular usage models like video playback, video
conferencing, camcorder functionality, video telephony, and digital TV.
• An enhanced set of peripherals eases connectivity to technologies like Wi-Fi, WiBro, WiMAX, and Bluetooth v1.2,
and the Quick Capture interface supports camera sensors up to 2–3 megapixels (MP) for richer camera applications.
• Package options of a discrete 14x14 mm package and a 15x15 mm package-on-package (PoP) package with stacked
NAND flash and mobile DDR memory enable sleek form-factors.
OEM AND CARRIER BENEFITS
Manufacturers benefit from devices featuring the PXA320 processor by being able to showcase higher-end phones and PDAs,
personal multimedia players, embedded industrial handhelds, Mobile Internet Devices (MIDs) and other portable devices
with cutting-edge features at an efficient cost. A comprehensive support package enables OEMs to take advantage of available
leading operating system images, optimized multimedia codecs and middleware, tools, and applications supported by a rich
hardware and software ecosystem, accelerating time to market (TTM) and return on investment (ROI).
Network operators benefit from the new capabilities in the PXA320 processor. With up to 806 MHz of processing power, along
with a large level 2 cache and frame buffer, the user will be able to enjoy the benefits of complex and concurrent usage models
that increase average revenue per user (ARPU). For example:
• With long battery life and powerful video processing, consumers can enjoy advanced features of 3G and HSDPA
networks—such as streaming H.264 VGA video—for extended periods.
• The available performance in the PXA320 allows a customer to simultaneously listen to an MP3 file, play a video game,
and have a voice conversation.
CODE COMPATIBILITY AND ECOSYSTEM SUPPORT
The PXA3xx processor family is the third generation of applications processors based on the Intel XScale® technology. To
preserve existing investments in applications software, the PXA320 processor maintains backward compatibility with previous
PXA processors, as well as processors within the PXA3xx processor family. To further reduce time-to-market (TTM), Marvell
provides tuned and validated Windows Mobile, Windows CE, and Linux board-support packages, codecs and multimedia
frameworks, and OpenGL-ES 1.1 libraries, as well as optimized compilers, debuggers, and profilers.
The vast ecosystem of software and hardware vendors continues with the Marvell PXA3xx processor family to provide rich and
differentiated platforms. Over 150 applications and codecs are optimized for the processors, and more than 30 leading hardware
vendors provide support with development environments and devices. Combine these offerings with the high-quality
documentation and support, and OEMs/ODMs have a path to cost-effective handsets and handheld devices to increase ROI.

H.264 compressed video, video playback from network services,
video conferencing, and in-home entertainment systems.
• Multimedia acceleration with Intel® Wireless MMX™ 2 technology
• Support for audio, video and other multimedia processing via SIMD
co-processor. The PXA320 supports up to D1, 30fps decode and up to
CIF, 30fps encode, depending on the codec format.
• Code compatibility
• Improves TTM by allowing manufacturers to reuse applications written
for PXA technology or ARM-compliant processors, and lowers development
costs by reducing the number of resources required for a derivative product.
Allows high degree of hardware and software reuse, migrating from the
PXA270 processor and other processors in the PXA3xx processor family.
• Versatile interfaces
• Integrated interfaces, including NAND memory controller, USB2.0 high-speed
device, and Enhanced Quick Capture technology, enable the implementation
of complex usage scenarios at a competitive cost. Enables easy connectivity
to 3G wireless baseband modules, DVB-H, Wi-Fi, WiMAX, Bluetooth v1.2,
and other peripherals. Supports a wide variety of camera sensors up to
2–3 MP resolution.
POWER-EFFICIENT SCALABLE PERFORMANCE TO 806 MHz
The PXA320 processor provides million of instructions per second (MIPS) on demand to 806 MHz, speeding Web-page browsing
video encode and decode applications, file compression, and PIM/office applications among others. The micro-architecture,
combined with an L2 cache and support for 130 MHz 32-bit DDR SDRAM memory provides headroom to support multimedia
evolution, application multitasking, and complex use cases. But advanced performance does not come at the cost of battery life.
Fine-grained power modes integrated into the processor design, an Instruction Power Manager (IPM) for dynamic voltage and
frequency scaling, and an advanced 90 nm process enable power-efficient performance, resulting in long battery life.
