The RMI Alchemy™ Au1200™ processor leverages a 30-year commitment to developing high-performance, low-power solutions to provide a purpose-built, versatile processor for Personal Media Player (PMP), Automotive, and Digital Media Adapter (DMA) applications. The RMI Alchemy Au1200 enables users to download media quickly and enjoy DVD-quality video efficiently delivered at full-frame rates, with low power, and with ample product features.

The RMI Alchemy Au1200 processor gives system designers an easy-to-use, simple solution to create full-featured PMPs with greatly reduced design cycle times. System-on-a-Chip (SoC) architecture eliminates the need for additional components.

Transcoding not required

The Au1200 processor supports common digital video media, including MPEG, DivX, and WMV9, and delivers full D1 resolution without the need to transcode content between PC or PVR and the PMP. This reduces the time required to download fresh content and helps enable consumers to take media “on the go” faster and easier.

The Au1200 processor also leverages a unique approach to DDR1 and DDR2 memory to deliver better overall performance than SDRAM components. And the Au1200 processor achieves faster I/O via USB 2.0 to give designers a range of enhanced connectivity options.


No need for DSPs

The RMI Alchemy Au1200 processor incorporates an integrated Media Acceleration Engine optimized for video to eliminate the need for DSPs and specialized coding. This means less overall power consumption and a simplified design.

LCD controller design optimizes displays

The RMI Alchemy Au1200 processor features an LCD controller that gives developers full 32-bit RGB capabilities in each of four prioritized overlay windows that require no frame buffer modifications to reposition. The processor also features gamma correction for matching video displays with graphics, a global background color that simplifies processing and produces an aesthetically pleasing display, and a 1KB palette RAM frame buffer that is ideal for displaying information in portable device idle modes.


Camera interface module supports today's popular features

The Au1200 processor also features a Camera Interface Module (CIM) that provides an 8 or 10-bit data bus for input from CCD/CMOS sensors or other CCIR656 data. The CIM supports pixel clock rates up to 33MHz, and adds popular capabilities including image capture and analog TV display.

CIM image data is autonomously planarized in RGB or YCbCr format, relieving the core from additional work, and is routed to three separate FIFOs. Output is then moved to memory using DDMA. Planarized data can take advantage of the scaling, filtering, and color space conversion capabilities of the MAE.

A ready-to-go solution for designers

The RMI Alchemy™ Au1200™ processor gives designers an easy-to-use and fast tool for developing innovative and feature-rich products that can be produced and marketed quickly, shortening the design-to-market cycle for OEMs.

The complete processor solution includes ODM design and hardware components, third-party GUI and content management software, and RMI media player software with no licensing fee. Overall, the solution features fewer parts for easier design and simpler integration. Flexible architecture provides a robust capability for numerous portable media applications.
