Designed as an ideal silicon solution for audio video receivers
and DVD receivers, the new CS49500 family integrates two
programmable 32-bit DSP cores and a DMA engine with a full set of
audio peripherals. Feature-rich designs can be easily developed
using the Cirrus® Audio Software Library, which includes both certified
application programs and a modular plug-in environment for easy
customization using Coyote32 assembly or C programming. The
framework includes certified state-of-the-art audio decoders, virtualizers,
surround simulators, and audio-enhancement algorithms.
The CS49500 family is designed to reduce system costs and development
time and provide features and flexibility for competitive system-level
solutions. Difficult processing tasks that incorporate Dolby Digital
Surround EX, AAC multichannel, DTS-ES 96/24, and THX Ultra2
Cinema can now be accomplished without the expense of external
logic or memory. Additionally, the CS49500 family meets the needs
of today’s high-end audio systems with twin DSP cores, I/O intensive
designs that support up to 10 input and 16 output channels, and on
the CS49520 design, support for simultaneous dual-decode.
Delivering an extensive selection of silicon and software capabilities,
the CS49500 family is an excellent Total Entertainment (Total-E™) IC
Solution for your next-generation digital home entertainment product.
