Introduction
The AML6210DP A/V processor is a complete integrated system targeting the digital picture frame market.
The device combines a super fast JPEG decoder, all digital LCD drivers/TCON signals, USB and card-reader
I/Os and a 32-bit host CPU in a small 144 pin package.
The embedded 32-bits core CPU handles all system related application software. It executes AVOS, the base
operating system for AML6210DP. All applications and drivers run on top of AVOS. Drivers including USB
drivers, card-reader hardware driver, and video and other hardware related programming interfaces are provided
by AVOS. Applications include graphical user interfaces and file system sub-system are also included.
Developers can add additional applications to customize for each platform.
The core CPU interfaces to the video and audio processing hardware. It performs advanced digital audio
decoding. It provides support for all existing audio formats and it also has enough flexibility to accommodate
new audio standards. Popular audio formats like MPEG Layer I/II/III, LPCM, MP3, WMA, AAC and WAV
can be supported.
JPEG pictures are processed by dedicated picture decoding hardware and the flexible Picture AMRISC
TM
engine. The hardware and microcode combination is capable of decoding JPEG pictures with no limits in
picture resolution. Once decoded, the output pictures are passed to a sophisticated video sub-system that
performs image analysis, enhancement and scaling functions. Contrast enhancement, hue adjustment, video
scaling, video interpolation, and zoom are also supported. The high-resolution scalar supports both up-scaling
and down-scaling of images and video. The scalar can also mix in multiple graphics and OSD layers for the
final display. The integrated video encoder supports all digital LCD panel resolutions thru the on-chip triple
panel DACs. In addition, a programmable digital LCD TCON is included for the AML6210DP to interface to
digital LCD panels directly.
The AML6210DP also integrated a USB 2.0 High Speed OTG controller/PHY and card-reader controller. The
card-reader controller can support SD/SDHC, MS/MS-Pro/MS-Duo/MS-Pro Duo, MMC, xD and CF cards.
FAT and FAT32 file systems are supported. The USB controller can be connected to USB hard disk, FLASH
drive, digital cameras and MP3 players. The AVOS drivers and applications for AML6210DP firmware
includes the basic USB device driver, USB protocol stacks to support bulk and INTR transfer, Hub, Mass-
Storage (MS) class and Picture Transfer Protocol (PTP). The AVOS USB firmware also supports multiple file
systems and includes flexible file transfer functions between USB devices.
AML6210DP A/V processor has a set of very flexible clocking circuits that implement the adaptive
AMPOWER-II power reduction algorithms. The chip works in conjunction with the AVOS software to
reduce total power consumption based on processing load, type of media streams being processed and the output
requirements. With AMPOWER-II, the system can reduce power consumption for portable applications and
helps consumer electronics to achieve the Energy Star rating. In addition, AMPOWER-II also provides higher
performance within smaller, thermally constrained environments.
