  1. TI Rips into High-Speed Encoding with up to 16X Recording for High-End Consumer Audio Vineet Ganju Performance Audio Marketing Manager

  2. High-Speed Encoding Addresses Trends in CE and Automotive Markets • Home Media Servers, HDD based stereo systems, High Speed CD rippers • Growing variety of consumer equipment capable of audio storage • Need to be able to rip music quickly without the complexity of a PC • Need low-cost, consumer equipment price points • Navigation, Multimedia Systems, Virtual CD changers and A/V Foundation Systems • HDD in navigation systems used as audio storage • Eliminate mechanical CD changers with NAND • Need to playback from other than radio/CD (USB, SD/MMC) • CD Ripping needs to be quick and transparent

  3. High-Speed Encoding Market Needs • End User Experience • Users don’t want to spend a long time ripping CDs • System should be usable for other functions while ripping • Cost-effective System • Needs to be cost-effective versus a PC-based system • Needs to hit consumer price points • Design Flexibility • Design final product from menu of hardware interface options • Design final product from menu of software algorithms • Time to market • Growing and evolving consumer/automotive encoder market • Need to get products out quickly to capitalize on current trends

  4. TI’s New High Speed Encoding System Solution • Leverages TI’s expertise in AVR and automotive audio markets • Solid foundation in multi-channel decoders for CE and automotive markets • Home audio solutions becoming central driver of home media experience • High Speed Encodesolution improves end user experience • Fast transfer from CD to storage with up to 20X ripping speeds • Simultaneous encode and decode enables listening while ripping • Consumer price points • DSP manages all the interfaces eliminating microcontroller cost • Single DSP for encode and decode reduces chip count • Modular, scalable solution allows tailoring to meet cost target • Design flexibility • Supports choice of popular encode formats including MP3, WMA, ATRAC3, and AAC • Interface to CD, USB, HDD, NAND, Disk-On-Chip and others • Time to market • Drivers, encoders, decoders, and system software included as part of the solution • High Speed Encode EVM is a full prototype system • 3rd party Mistral helps speed design and customization

  5. Rip Audio QuicklyStore a 60min CD in 3min with ATRAC3 Encoder Speed Benchmarks • DA710 @ 300MHz – Encode Only 0 5x 10x 15x • MP3 Encoder (128kbps/44.1kHz/stereo) MP3 12x • WMA Encoder (128kbps/44.1kHz/stereo) WMA 12x • ATRAC3 Encoder ATRAC3 20x • ATRAC-Plus Encoder ATRAC-Plus 12x AAC • MPEG2 AAC LC Encoder 12x

  6. Enhancing User Experience While Reducing System Cost Enhanced user experience: • Simultaneous encode and decode enables listening to audio while ripping. System cost reduction • DSP controls interfaces eliminating microcontroller cost • Single DSP for encode and decode EXTERNAL STORAGE SDRAM TMS320DA710 Nand Flash Up to 20x CD ripping Host Micro / Head Unit I2C Communication HDD Encode MEDIA SOURCE ATAPI CD Loader Data Serial CD Loader USB OTG Controller USB CTL PLAYBACK SD Card McASP* Audio Data Output (DAC) Radio McASP Decode DVD Player Audio Data Output (DAC) * Multi-channel Audio Serial Port
