Dallas Texas Instruments 8-channel TAS3108 audio DSP offers high-performance audio processing capabilities that enable up to 7.1-channel processing in digital TVs, home theater-in-a-box systems, and automotive head units and external amplifiers.
The TAS3108 audio DSP can perform five simultaneous instructions per clock cycle and operates at 135MHz, providing a maximum of 675 MIPS. When combined with its 48-bit data path, and single-cycle 76-bit (48x28) multiply-accumulate, the TAS3108 DSP boasts 135 million multiple accumulates per second (135MMACS) performance.
The TAS3108 DSP comes with a set of tools that is optimized for audio processing, enabling the efficient implementation of proprietary algorithms and standard features such as equalization, tone and volume control. The tools are composed of two essential parts, the Graphical Development Environment (GDE) and the Integrated Development Environment (IDE). The GDE is a graphical drag-and-drop environment that allows users to take pre-optimized components and drop them into place. They can then program and control each component in real-time, as well as publish their own components with proprietary algorithms.
The IDE is a traditional tool consisting of an Editor and Simulator/Debugger tools. The Editor will show the customer context sensitive coloring and help guide them on what to input, enabling quicker programming and fewer errors. The Simulator/Debugger provides a PC-based environment, allowing customers to debug their code by testing it, while watching memory and setting breakpoints.
Automotive audio applications possibly benefiting from this device include audio head units and external amplifiers. With support for sample rates from 32 kHz to 192 kHz across 15 stereo/TDM data formats, developers can target a broad range of markets with a single design. An automotive version of the solution, TI's TAS3108AI, is AEC Q100 qualified.
The TAS3108 audio DSP has enough processing power to provide home audio developers with full control of audio processing, including matrix decoding and a variety of surround sound schemes. Leveraging the flexibility of the TAS3108 DSP and TI's development software, developers can quickly add custom algorithms, equalization, dynamic range compression for TVs, home theaters in a box and mini-component systems. The availability of extensive performance headroom enables OEMs to differentiate their products through enhanced features and exceptional sound quality (for instance, a turnkey Dolby ProLogic II implementation only requires 30 percent of the TAS3108).
