Product Overview
The AMD Alchemy™ DBAu1200™ development board kit is an all-inclusive hardware and software tool suite that enables product developers to quickly and easily design and test next-generation digital media devices. The kit includes a complete set of features for the development and testing of operating system and application software for products based on the low-power, high-performance digital media capabilities of the AMD Alchemy Au1200™ processor.
The DBAu1200 development board kit is a logical extension of the capabilities of the Au1200 processor. This System-on-Chip (SoC) provides on-chip decoding of virtually all digital media formats, including MPEG1, 2, and 4; DivX 3, 4, and 5; H.263; and WMV9 video at D1 resolution (720 x 480) on handheld media-rich devices, without the need for transcoding.
The development board is designed to optimize the strengths of the AMD Alchemy Au1200 processor, such as its unified memory architecture, descriptor-based DDMA engine, and broad device support.
Hardware
The AMD Alchemy DBAu1200 development board kit is delivered complete and is configured and ready to run all leading development software programs. The development board kit is designed around the Au1200 processor and also includes DDR2 and Flash memory devices, all other associated semiconductors, and connectivity support for all peripheral devices.
The tool also features programmable serial controllers and power supplies. The kit is delivered with a 1.3-megapixel digital camera, and an EJTAG header supports monitoring and debugging and provides full-board reset.
Software and Documentation
The DBAu1200 development board kit helps designers become productive quickly with an included Quick Start CD that contains a WinCE demo and media codecs, plus the Linux operating system kernel and Linux development tools.
The development tool also includes Personal Media Player (PMP) and Digital Media Adapter (DMA) applications that can help to produce enhanced development cost savings. In addition to a Quick Start Guide, the CD also contains processor design files, application notes, the YAMON monitoring and debug assist software, and data sheets for each major board component.
