Designed as an ideal silicon solution for audio/video receivers and DVD receivers, the CS4953xx audio DSP 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 programming environment for easy customization. The framework includes certified state-of-the-art audio decoders, virtualizers, surround simulators and audio-enhancement algorithms. The CS4953xx, which features Cirrus Logic’s award-winning Intelligent Room Calibration Software for optimization of in-room acoustics, is designed to reduce system costs and development time while providing 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 CS4953xx family meets the needs of extensive processing power with twin DSP cores and input/output intensive designs with support for up to 10 input and 16 output channels. The CS4953xx is an excellent Cirrus Logic Audio DSP IC solution for next-generation digital home entertainment products such as audio/video receivers and DVD receivers. Support for home audio applications is through a third party. Please contact your local sales representative for information.
