DSP Video Processing via Open-Source APIs
Digital signal processors offer outstanding multimedia performance. Typically, they require just 40 percent to 50 percent as many cycles as a general-purpose processor (GPP) core to run a codec (encoders/decoders). They also offer far greater flexibility and reconfigurability than ASICs. Yet until now, programmers have had to learn proprietary languages to take advantage of the benefits of DSPs in digital video applications. But the emergence of application programming interfaces is eliminating the need to learn these proprietary DSP languages. APIs make it possible to easily leverage DSPs from applications running on the GPP.

Open Source Embedded Asterisk-based PBX
Building an embedded IP-PBX represents a significant paradigm shift from existing open source PBX designs that typically use PCI cards on x86 platforms. Until recently, current micro controllers
(e.g. those in the 200MHz ARM & MIPs class) typically lack the DSP
horsepower for multiple channels of speech compression or echo
cancellation that is required for analog line interfaces. The Analog
Device Blackfin chip has changed all this......
