The broad range of communication systems are almost all based on MCU, DSC and DSP SoC technologies along with deeply embedded software to provide control, signal processing and message routing. From a low cost handheld touch panel phone through to routers, a variety of algorithms can be processed by the combination of SoC processors and either Unison or DSPnano.
Typical algorithms include:
- RAKE Receivers
- UTMS
- (I)FFT
- Symbol encode and decode
- Virterbi decoding
- Adaptive equalization
- Adaptive filters
- Timing recovery
- Motion estimation
- Image compression
- Cordic beamforming
- Walsh Fourier Transform
All of these algorithms are used for a wide range of different communication modems and compression/decompression techniques. By having modular building blocks for functions like this, more tried, proven and reliable systems can be assembled quickly and easily. Often, these algorithms are expressed in more general matrix formulations and more general matrix math support is provided depending on the processor style and the vendor customer base.
Typical processing for connectivity requires extensive networking protocols including NAT, HTTP, Telnet, USB, DHCP, PPP, WIFI, Zigbee, Bluetooth and more. Using SoC processors along with industry standard APIs and off the shelf ultra tiny operating systems, OEMs can reach the market quickly with low risk.
