Optimized for Multi-function Personal Media Player (mPMP) Applications

Overview
NetLogic Microsystems’ industry-leading Alchemy® Processor family comprises a series of ultra low-power embedded processors that deliver the powerful processing performance, ultra low-power functionality and market specific integration required for next-generation products like enterprise thin clients, automotive infotainment, telematics, and other media rich embedded applications.

The Au1250® processor is pin- and software-compatible with the existing NetLogic Microsystems Au1200® processor’s sockets while providing significantly increased performance advantages associated with the Low-Power Embedded processor family. The architecture allows system designers the ability to implement full featured PMPs using the Low-Power Embedded processors without the need for additional components.

This elevated application processing performance, with remarkably low power, makes the Au1250 processor ideally suited to the expanding needs of multi-function media rich applications. The Au1250 processor’s optimized design is tailored to efficiently support multi-format video playback, GPS navigation, mobile TV, satellite radio, along with photo viewers, digital cameras and other applications in a single, low-cost, portable design.

700MHz Means More Available MIPS
The Au1250 processor at 700MHz provides 17% more CPU performance compared to the 600MHz version. When simultaneously playing full D1 video using the on-chip Media Acceleration Engine™, which off-loads video processing in hardware, the Au1250 processor delivers more available MIPS for other user applications than have been possible in portable consumer devices. Users can now enjoy unprecedented processing performance for simultaneously running multiple diverse applications with substantially longer battery life than before.

Support for Large Block NAND Boot
Another advantage of the Au1250 processor is the expansion of the memory implementation options that are available to a designer. The Au1250 processor enables boot start-up directly from large block NAND memories. Today’s large block, multi-level cell NAND Flash memories are much denser than previously available, allowing higher capacities and lower memory costs. Lower cost-per-bit makes NAND Flash an attractive option for portable storage. The Au1250 processor recognizes this trend by supporting the access requirements of large block NAND memories. System designers now have the flexibility to boot from large block NAND as well as NOR Flash memories.

Extended Temperature Versions
For systems with DDR2 memories, the Au1250 processor is available in an extended temperature range option of -40ºC to 100ºC for speeds up to 500MHz. This is well suited for select in-cabin automotive applications, and other environments with more hostile temperature requirements.

The Low-Power Embedded processor family of pin-compatible Media and Navigation chips enables designers to support multiple price-performance points and application requirements from a single board design.
