Description
The AS3530 is austriamicrosystems´ digital system for its new generation mobile entertainment platform. It's flexible architecture allows single chip solutions for high performance power optimised audio and video products with minimum count of external components.
The device can be configured in two ways: for pure
audio products the video decoder and parts of the main
memory can be configured into power down. For video
applications the video decoder hardware will be enabled
and the speed of the system will be scaled to the actual
demanded video decoder complexity and resolution. All
video decoder features for H.263/MPEG-4/H.264 and
VC-1 are implemented in a dedicated video hardware
accelerator for minimal power consumption and also
ultra low main processor load.
Using low power deep submicron technology gives outstanding
performance in terms of power consumption
and utmost integration densities for embedded on-chip
RAM and ROM areas.
The AS3530 is intended as microcontroller chip including
all digital function blocks necessary for a portable
audio or video player. These function blocks include onchip
RAM and ROM memories, interface blocks for data
transfer and storage like USB, IDE, NandFlash, MMC,
SD, SDIO, CE-ATA, hardware acceleration for video
decoding, clock generation and digital power optimisation
functions.
Based on the ARM926-EJ with large on-chip instruction
and data caches and integrated MMU, the system gives
full support for all kinds of operating systems from simple
RTOS implementations up to Symbian OS, micro
Linux and Windows CE.
For all audio input/output and power management it is
intended that the chip is used in combination with austriamicrosystems
audio AFE products (e.g. AS3514/
AS3515/AS3517/AS3518/AS3519).
For the chip family MCM derivatives with integrated AFE
and integrated mobile SDRAM are planned as future
products.
Austriamicrosystems provides a total system solution
reference design including all necessary software blocks
for low level HW drivers, device IO functions and a dedicated
reference application with common audio and
video features.
Austriamicrosystems runs a comprehensive software
partnership program which allows authorised software
partners to provide variety of audio or video extensions,
applications or total solutions based on austriamicrosystems
powerful portable multimedia platform.
