The RMI Alchemy™ Au1250™ media processor extends the strengths of the existing Alchemy processors into a broad range of digital media applications. The Au1250 processor is pin- and software-compatible with the existing RMI Alchemy™ Au1200™ processor’s sockets and leverages the Au1200 processor’s success in Portable Media Players (PMPs), Automotive, Infotainment and Digital Media Adapters (DMAs), by providing significantly increased performance while improving its power optimized advantages associated with the Alchemy processor family. The System-on-a-Chip (SoC) architecture allows system designers the ability to implement full featured PMPs using the Alchemy 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 Portable Media Players (mPMPs). 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.
