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.
