Compilers and Toolchain Support LTE Development
Altair Semi uses Green Hills Software's MULTI IDE for development of 4G LTE products

SANTA BARBARA, CA — December 6, 2011 — Green Hills Software, the largest independent vendor of embedded software solutions, has announced that its compilers, the Green Hills Probe and MULTI® development tool chain, have been used by Altair Semiconductor in the development of its 4G LTE products. Altair is a leading LTE chip supplier with approximately 30 different customer products shipping globally, covering all variants of the LTE standard on a single chipset and software platform.

"We selected Green Hills Software after conducting an extensive analysis of the solutions in the market," said Nohik Semel, vice president of systems engineering, Altair Semiconductor. "The Green Hills compilers showed excellent performance and memory footprint, which was particularly important for us given the speed and power constraints imposed by 4G systems. The hardware and software tools have helped us considerably in the development of the firmware for our products."

Altair is a leading developer of ultra-low power, small footprint and high performance 4G LTE chipsets for the 4G wireless broadband technology LTE (Long Term Evolution). LTE meets the requirements of next-generation networks including downlink peak rates of at least 100Mbit/s and uplink of at least 50Mbit/s. The company's product portfolio, which utilizes cores from MIPS Technologies, includes baseband processors, multi-band RF transceivers and a range of reference hardware and product level protocol stack software.

Christopher Smith, vice president of marketing, Green Hills Software, commented, "The next generation of wireless communication technologies operates at data rates and bandwidths that put increasing demands on semiconductor and system developers. In order to optimize the performance and power consumption of the components, it is important to develop the most efficient code possible in the shortest time. This is where Green Hills Software's development tool chain has a proven track record across a broad range of applications."
