By Richard Goering – At CDNLive, Frank Schirrmeister, group director of product marketing for the System and Software Group at Cadence, talked about how Verizon came up with a new app to get National Football League (NFL) video on cell phones. This created requirements that rippled through the network and the design value “stack.” The network needed more bandwidth and the devices needed more capabilities. One result of such developments: “anybody in the supply stack needs to supply more.”
As a result of the demand to “supply more,” IP developers are now building integrated subsystems. This is, in part, what the recent Cadence agreement to acquire Tensilica is about. And chipmakers have become responsible for providing much of the software stack, including drivers, OS, and middleware. As Schirrmeister noted, no longer is it enough to just partner with a provider like Symbian or Palm for an operating system, as it was back in the 1990s. Now, semiconductor companies must provide the chip with the OS up and running, and the trend towards open source operating systems like Android and Linux is amplifying this trend even further. more> http://tinyurl.com/c468w2f
