AMD Debuts Media CPU, Partners With TiVo

From the press release:

The Au1200 processor has been optimized for personal media players (PMP) and enables a new generation of conveniences and features, including scalable DVD-quality displays, effortless video content transfers directly from digital video recorders, and long-lasting battery life so consumers can stay mobile longer.

This enhanced functionality is a result of the Au1200 processor’s integrated media acceleration hardware and accompanying media player software. The solution does not require a digital signal processor (DSP) nor complex DSP coding, enabling PMP manufacturers to speed products to market more quickly and potentially offer the devices at more affordable prices.  Read more...

LG Electronics Unveils DMB-Receiving Phone

The DMB mobile phone adopts the DMB-receiving System-on-Chip (SoC) that the company developed last month. The chip enables the user to watch terrestrial broadcasts and at the same time talk on the phone.

LG Electronics has technologically brought the usual home TV antenna function aimed at receiving VHF broadband DMB into the small phone. The handset also adopts DSP (Digital Signal Processor)-based SoC (System-on-Chip), mobile phone-fit low power consumption and design technologies for making the device small.  Read more...

Future Format Frenzy: Digital Audio And You

Quote from the article at AnandTech.com:

“While little is known outside enthusiast high fidelity circles, some DVD-A media and sampling are already shipping. Mitsubishi’s newest line of DVD players uses the processor that supports DVD-A. As you may have guessed, DVD-A is simply higher fidelity audio written to DVD media instead of CD. However, DVD-A has a data rate of almost seven times that of an audio CD. This allows us to encode/playback more channels at higher frequencies and bitrates. DVD-A supports five-channel audio while CD uses only two.  Read more...

TI Ships Industry’s First 1 GHZ DSP

Texas Instruments have announced the release of a new 1 GHZ digital signal processor (DSP). DSPs are chips used in many devices to convert analog signals into digital data. The TI announcement means that devices using this technology can operate faster, and possibly become cheaper to manufacture.

From TI’s press release:

Giving customers the performance they demand to develop future innovative applications, Texas Instruments (TI) today announced it is now shipping the world´s first 1 GHz digital signal processor (DSP), leveraging the 90 nanometer (nm) process node.  The new 90 nm process has also been applied to the existing TMS320C64x 720 MHz parts, enabling customers to save more than half the price on these devices.    Read more...

Israeli CPU computes at speed of light

Lenslet said its processor will enable new capabilities in homeland security and military, multimedia and communications applications.

“Optical processing is a strategic competitive advantage for nations and companies,” said Avner Halperin, vice president for business development at Lenslet.

“Processing at the speed of light, you can have safer airports, autonomous military systems, high-definition multimedia broadcast systems and advanced next-generation communications systems.”

An optical processor is a digital signal processor (DSP) with an optical accelerator attached to it that enables it to perform functions at very high speeds.  Read more...

New Cirrus Logic Surround-Sound CODEC

The CS42406 is ideally suited for audio/video and DVD receiver (combination DVD player/audio receiver) manufacturers searching for a cost-effective, surround-sound CODEC solution that delivershigh-quality sound and bears the mark of audio excellence from Cirrus, the global leader in audio solutions (source: Forward Concepts, April 2003).

The CS42406, which features two analog-to-digital (A/D) and six digital-to-analog (D/A) channels, runs off 3 V to 5 V analog and digital power supplies. The A/D converters and D/A converters allow for simplified system design by providing single-ended inputs and outputs. Cirrus’ CS42406 also features integrated level shifters that are designed to eliminate the need for external components in order to connect the CODEC with the system’s host digital signal processor. In addition, Cirrus’ patented Popguard® technology feature helps to simplify system design, reduce overall system costs and eliminate the
