Chapter 1SLEU093 – March 2008
Overview
The TAS3308EVM PurePath Digital™ customer evaluation module demonstrates the Digital AudioProcessor TAS3308 from Texas Instruments (TI).
TAS3308 is a fully programmable high-performance audio processor. It uses an efficient, custom,multi-instruction programming environment optimized for digital audio processing algorithms. TheTAS3308 architecture provides high-quality audio processing by using a 48-bit data path, 28-bit filtercoefficients, and a single-cycle 28 ×48-bit multiplier with a 76-bit accumulator. An embedded 8051microprocessor provides algorithm and data control for the TAS3308. The TAS3308 is the commercialversion intended for home audio and other commercial applications.
This is a single board EVM. EVM can be configured with a TAS5601 or similar power stage. Thiscombination will provide complete signal processing and power amplification system solution whichincludes digital input/output (S/PDIF), analog inputs/outputs, interface to PC and DAP features like digitalvolume control, input and output mixers, auto mute, equalization, tone controls, loudness, dynamic rangecompression, surround effects.
The TAS3308 is well suited for inclusion in Digital Televisions, Home Theater Systems, Mini-ComponentAudio Systems and Pro-Audio systems.

The primary usage mode of the EVM is to provide a software development platform that receives thecontrol and signal processing flow descriptions from a PC running the PurePath Studio GraphicalEnvironment (GDE) or Integrated Development Environment (IDE) through the USB interface. In thismode of operation, the user will develop a signal processing flow (applications) and components using thePurePath Studio. The resulting programs can be loaded into the EVM EEPROM. The TAS3308 will thenload the EEPROM contents and execute the signal processing flows. During execution, many of theTAS3308 signal processing flow parameters can be dynamically changed using the PurePath StudioGraphical development environment. Additional information on using the EVM with the PurePath Studiodevelopment environment is included in subsequent sections of this document and in the PurePath Studioonline documentation.
The EVM has a Reset Button which resets all of the board logic. A red RESET LED is lit when Reset isactive. The EVM also has a Mute button to mute the TAS3308 outputs. The Mute function is automaticallyactivated following a reset. A yellow mute LED is lit when Mute is active.
The EVM also contains a MSP430F2252 controller that can be programmed to provide stand aloneoperation using the EVM push buttons or an IR remote input. The microcontroller interfaces to theTAS3308 through the I

C, GPIO, and the Reset control lines. The microcontroller has and IR receiver,eight (8) circuit board pushbuttons and eight (8) LEDs to support user inputs.
