Chip vendors zero in on wireless Product News 5/29/2003 Post a comment Power-managing ICs in wireless products are now playing a major role in system-level solutions. Cell phones, which are being combined with PDAs and cameras, are becoming increasingly small, dense and power-hungry, offsetting the size and energy density advances made by the lithium-ion battery sources powering them.
RF Engines Starts Licensing Polyphase DFT Cores as IP Product News 5/23/2003 Post a comment Signal processing specialist RF Engines Limited (Isle of Wight, UK) has added high-speed Polyphase DFT (discrete Fourier transform) cores to its range of DSP technologies. Dubbed the Ventrix range, the core is intended for applications where filter performance and processing speed are critical and optimal use of the available silicon is required. They provide advancec filter banks to process complex input data in continuous real time with no gaps in data, at rates of up to 800 mega-samples per s
TI Rolls Processor for IP Telephony Product News 5/23/2003 Post a comment Texas Instruments Inc. will up its ante in the voice-over-Internet Protocol market this week with the release of an IP phone processing engine built around a C55x DSP and a MIPS core.
Samsung Electronics Develops 4-Color Channel TFT-LCD Product News 5/23/2003 Post a comment Samsung Electronics announced the industry's first 4-color channel TFT LCD technology at the Society for Information Display Symposium in Baltimore this week. Conventional LCDs have subpixels for three primary colors -- red, green and blue (RGB). With a 4-color channel, Samsung added a white subpixel to maximum brightness for optimum display viewing
