TI Introduces New Aureus DSPs And Software Library
Texas Instruments introduced new solutions in its Aureus family of audio digital signal processors (DSPs) for applications requiring multi-channel decoding, including audio/video and DVD receivers, home-theater-in-a-box systems (HTIBs), set-top boxes, mini-compos, high-definition televisions (HDTV) and automotive navigation/multimedia systems.
The new 300 MHz TMS320DA710 and 250 MHz TMS320DA708, according to the vendor, offers 50% performance improvement at the same price point as the previous generation of Aureus products. A complete 7.1 system, including AC3 or DTS decoding, Dolby ProLogic IIx or NEO:6 matrix decoding, bass management, and delay, is claimed to take only 22% of the available performance of a DA710 processor.
The list of improvements includes architectural enhancements, new mixed-precision instructions, audio-optimized Dual Data Movement Accelerator (DMAX), CPU core and memory subsystem enhancements, and the increased amount of parallel processing.
DA7xx devices are backed by TI's Performance Audio Software Library, an end-to-end system software solution that includes:
- Industry-standard decoders and post-processors from Dolby, DTS and THX
- MP3, WMA and ATRAC3plus encoder and decoder modules
- Double-precision (64-bit) Bass Management
- The TI Effects Library, which includes configurable modules for Graphical EQ, Room Simulators and Matrix Decoders
- Optimized filter blocks for building custom algorithms
- Bitstream auto-detection, system framework and I/O drivers.
The Performance Audio Software Library is based on TI's XDAIS algorithm standard, which allows OEMs and third parties to create plug-and-play algorithms.
Currently sampling, both devices are slated for volume production in Q3 2005. The 250 MHz TMS320DA708 costs $13.52 each and comes in a 144-pin TQFP package. The 300 MHz TMS320DA710 costs $21.63 and comes in a 256-ball BGA package, both in 10,000 unit or more quantities.
