Marvell PXA320 Processor Series
KEY APPLICATIONS
Targeted devices include:
• High-end smartphones, PDAs, Mobile Internet Devices (MIDs), and personal media players with demanding imaging, video,
multimedia, and video conferencing capabilities.
• Wireless enterprise devices with built-in Wi-Fi, WiBro, and WiMAX.
• Embedded solutions featuring video telephony, video/voice over IP (VVoIP), and GPS.
PXA320 PROCESSOR KEY FEATURES
FEATURES
BENEFITS
• Scalable core up to 806 MHz, 256 KB L2 cache, 32-bit DDR interface
• Up to 806 MHz core clock provides burst-processing when needed. Powerful
core features enable faster data movement across the platform and offer
more headroom for multitasking applications, processing enhancements,
and complex use cases.
• Helps complete tasks sooner for better end-user experience and lower
power in computing tasks, such as Web browsing, file compression, and
other applications.
• Marvell® Scalable Power Manager
• Helps extend battery life in usage scenarios, such as phone standby, video
and music playback, and general-purpose applications processing. Includes
hardware and software processing to dynamically change the voltage and
frequency of the processor depending on the workload.
• 90 nm low-power process
• Low-power customized process allows for lower voltages and enables
low-cost solutions for the mobile market.
• 768 KB frame buffer
• Supports VGA-quality graphics for applications such as streaming
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.
