CS49500/10/20 Features

New Audio DSP Delivers High-End Performance

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

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.

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,

Solution for your next-generation digital home entertainment product.
