Reference design for wireless optical comms
A new technology from Texas Instruments dramatically cuts the cost and complexity of bringing the high-speed datarates of optical networking to end users.
TI reckons its new TMS320DA61x DSP generation enables manufacturers to quickly and cost-effectively deliver products that meet consumer expectations.
At 225MHz, the first device in this generation - the TMS320DA610 DSP - offers the highest performance available in the audio industry with 1800MIPS or 1200MFLOPS.
This is three times the performance of current designs.

Advanced TDMA technology to boost cable bandwidth
Texas Instruments has unveiled its new technology featuring end-to-end advanced TDMA that will enable a 50% increase in upstream plant capacity.
Manufacturers will now be able to provide consumers with a full suite of high-quality surround sound content such as Dolby Digital, DTS and THX, and still have headroom to add additional effects processing and other enhancements.
Texas Instruments also is currently working with Lucasfilm THX to include the full post-processing power of THX's new Ultra2 specification, available to qualified THX licensees.
Until now, these enhancements have only been available on high-end audio receivers.
They can include: multiple digital zones; speaker virtualisation; automatic room correction; and access to additional or new formats that operate at higher sampling rates or provide extra channels for a more lifelike audio experience.
The DA61x DSP generation is based on the proven silicon and tools of the code-compatible TMS320C6000 DSP platform, featuring peripherals such as a 32bit external memory interface (EMIF), two I2C ports and a 16-channel enhanced direct memory access (EDMA).
The DA610 DSP also features two new multichannel audio serial ports (McASPs) that allow up to 12 stereo channels of I2S per port.
These ports are also compatible with the Sony/Phillips digital interface (S/PDIF) standard.
These highly integrated technologies are seamlessly combined with an audio software framework that is accessible through TI's easy-to-use Code Composer Studio integrated development environment (IDE).
This creates a virtual plug-and-play environment for the highly optimized audio algorithms such as Dolby, DTS and THX.
With this difficult integration already complete, manufacturers can dedicate their engineering time and dollars to developing new value-added features that differentiate their products and get them to market more quickly.
By designing with the DA61x DSP system, manufacturers will also realise savings via a reduced bill of materials.
The current high-performance audio systems on the market generally feature one DSP for decoding, one DSP for post processing, one I2S Interface chip, a microcontroller and external ROM and RAM.
TI integrates all of these onto a single-chip system while offering the ability to add more features and decode more channels.
For manufacturers, this translates into lower cost and smaller on-chip real estate - both of which add up to savings that can be passed on to the consumer.
TI has collaborated with Momentum Data Systems (MDS), an established and respected supplier of signal processing sub-systems and design support services for audio applications.
MDS offers systems expertise in digital and analogue design.
It also develops software for audio applications such as surround-sound decoding modules and high-quality multichannel audio.
