The goal of Long Term Evolution (LTE) is to achieve higher data rates through more efficient transmission, and thus improving the cellular phone user experience by enabling powerful new devices. The changes required in this technology present new challenges for base station vendors and their suppliers. Supporting 4G systems efficiently requires a number of innovations in DSP design; these innovations are moving the industry toward SoC architectures to support such systems. This paper will explore how TI's new architecture enables the key features in 4G systems.

RoweBots Research, Inc., a supplier of tiny embedded POSIX RTOS products, today announced the launch and release of UnisonTM Version 5 and the open-source version of Unison Version 4. These two ultra-tiny embedded-Linux and POSIX compatible RTOSs open Renesas Technology Corp.’s SH-2A Microcontroller (MCU) family to Linux and POSIX compatible development for the first time.

Avnet Electronics Marketing and Xilinx Inc. said they have concluded their five-month, 37-city global X-fest technical seminar series. According to the companies, the free one-day training sessions offered practical, how-to system level design instruction featuring the Spartan-6 and Virtex-6 FPGA families from Xilinx, as well as key enabling technologies from suppliers including Cypress Semiconductor, Intel, Maxim Integrated Products, National Semiconductor, NXP, Texas Instruments and Tyco Electronics. Replays of the events are available online.

How's this for a wedge issue on a slow news week? When Xilinx announced earlier this year that it was changing one of its foundry suppliers from UMC to TSMC for the 28-nm node, it seemed like a blow to differentiation—at least from a process technology standpoint—between Xilinx and Altera, which has been using TSMC for years. But while Xilinx chose to go with TSMC's high-performance/low power process, Altera said this week it is going with TSMC's high-performance process. Altera maintains that customers in the high end communications equipment market are much more concerned about performance than power. Luanne Schirrmeister, senior director of product marketing at Altera, put it this way: "In communications infrastructure, nothing is battery powered. Everything is plugged into a wall."
