Wind River to roll DSP RTOS

Just as the 2002 Embedded Systems Conference got under way in San Francisco, Wind River rolled out a development platform for DSP-powered applications.

Known as VSPWorks, the new product is believed to be a key to enabling Wind River to keep a foothold in the wireless market, especially as that market migrates to 3G systems. "With the whole world getting so excited about 3G wireless, there's going to be a lot of interest in DSP," noted Daya Nadamuni, senior analyst for Gartner Dataquest. "Most of those systems are going to have a DSP on board."

The company's new platform will provide developers with the VSPWorks RTOS and a GUI-driven IDE. The IDE is said to be optimized for creating applications with small-memory footprint requirements using multiple DSPs or a combination of DSPs and traditional CPUs.

The new product rollout gives Wind River an entry into the DSP RTOS market, which up until now has been populated by a large percentage of users who wrote their own OS.

A few commercial OS have been offered up to now, including OSE Systems' OSE RTOS, which has been used by such customers as Ericsson and Agere Systems, and RidgeRun's DSPLinux OS. At the end of last year, RidgeRun teamed with Texas Instruments to deliver an "end-to-end" embedded Linux development suite for TI DSPs.

Still, commercial RTOSs haven't yet taken hold in the DSP market, analysts said. "A lot of DSP OS are still being developed in-house," Nadamuni said. "But that will start to change soon."

One reason for the change is the rising popularity of DSPs. A recent EE Times branding survey revealed that 55 percent of developers have used multiprocessor designs, and a large majority of developers say they are willing to move back and forth from traditional CPUs to DSPs.

"We're seeing increased complexity, as well as developers who are building systems with new kinds of components," said Gareth Noyes, market development manager for Wind River's DSP and multicore products.
