Morpho Technologies Demonstrates MPEG-4 Video for 2.5G and 3G Wireless Applications.tnash@morphotech.com Business Editors/High-Tech Writers Embedded Systems Conference San Francisco 2003 SAN FRANCISCO--(BUSINESS WIRE)--April 23, 2003 Morpho morpho Any species of New World tropical brush-footed butterflies in the genus Morpho (family Nymphalidae). Microscopic ridges on the wing scales break up and reflect light, producing the iridescent blue of the males of some species. Technologies continues to redefine the Digital Signal Processor A digital signal processor (DSP) is a specialized microprocessor designed specifically for digital signal processing, generally in real-time computing. Characteristics of typical Digital Signal Processors
One of the most significant applications and market drivers for 2.5G and 3G wireless communication is multimedia, specifically, digital video. The MPEG-4 video codec, the newest among many previous multimedia standards, allows low bit-rate compression/decompression of digital video data, as required in 3G wireless multimedia applications. Real-time streaming video, video-conferencing, and video-messaging require significant signal processing power. The ability to share this processing power with other applications within the mobile terminal allows for significantly reduced power consumption and silicon cost. Morpho Technologies' MS1 reconfigurable Digital Signal Processor (rDSP) Cores implement the complete MPEG-4 baseband processing in software while simultaneously performing applications such as WCDMA (Wideband CDMA) A 3G high-speed digital data service provided by cellular carriers that use the TDMA or GSM technology worldwide, including AT&T (formerly Cingular) and T-Mobile in the U.S. , 802.11a/b/g, GPS as well as others. The MS1 rDSP Cores execute these applications by running programs residing in flash memory outside the core. The MS1 architecture is optimized for mobile terminal applications including digital video and baseband physical layer processing. Many functions have been implemented on the MS1 family of rDSP Cores, including DCT (Discrete Cosine Transform) An algorithm that is widely used for data compression. Similar to Fast Fourier Transform, DCT converts data (pixels, waveforms, etc.) into sets of frequencies. The first frequencies in the set are the most meaningful; the latter, the least. , IDCT IDCT Inverse Discrete Cosine Transform IDCT Inverse Discrete Cosinus Transformation , Motion Estimation and Compensation, Pixel Interpolation interpolation In mathematics, estimation of a value between two known data points. A simple example is calculating the mean (see mean, median, and mode) of two population counts made 10 years apart to estimate the population in the fifth year. , CDMA (Code Division Multiple Access) A method for transmitting simultaneous signals over a shared portion of the spectrum. The foremost application of CDMA is the digital cellular phone technology from QUALCOMM that operates in the 800 MHz band and 1.9 GHz PCS band. Chip and Symbol Rate Processing, Error Correction including Viterbi and Turbo Codecs, and many others. These functions are available to Morpho's customers to use in their own designs that take advantage of the MS1 architecture. Morpho Technologies currently has two versions of its MS1 architecture, the MS1-64 and MS1-16, available in test silicon for customer evaluation. The MS1 rDSP Cores are available to customers as soft and hard IP cores as well as within the Morpho Technologies Development Systems. "Morpho continues to develop products to meet the ever increasing embedded signal processing demands of 2.5G and 3G wireless applications. The MS1 rDSP supports the rapid implementation of applications in software that have traditionally only previously been available in hard-wired ASICs," comments Todd Nash, vice president, Business Development, Morpho Technologies. "For example, the MS1 provides a complete software solution for multimedia terminals including the physical layer and media processing without the need for separate signal processing paths in silicon. This can significantly reduce silicon area, power consumption, and development time." Morpho Technologies will be demonstrating both the MPEG-4 Codec and WCDMA baseband processing solutions running in real-time on development systems in booth 620 within the SoC Pavilion at the Embedded Systems Conference, April 23rd through 26th, 2003, at the Moscone Convention Center, San Francisco, California “San Francisco” redirects here.
