Coresonic AB was formed as a result of a need to develop a new wireless baseband processor architecture that was programmable but did not suffer the usual downsides of increased power consumption and cost. They were founded in 2004 based on the outcome of a three-year research project at the research center Stringent at Linköping University, Sweden. The founders include Professor Dake Liu, Dr. Eric Tell, Dr. Anders Nilsson and Professor Christer Svensson from the electrical engineering department who bring together decades of experience from research, development and marketing of semiconductors and IP. Its patented architecture offers a solution to the key issues faced by developers of baseband products for the WiMAX and 4G market. They provide a semiconductor core design and support the core with protocol specific firmware solutions. These deliver the flexibility necessary to both stay on top of the changing standards, and to cope with the myriad combinations of standards whilst using the same architecture. The optimized design delivers significant gains in power efficiency and cost over traditional programmable or DSP based architectures that are needed to drive high volume solutions. The flexibility allows wireless chip designers to gain much earlier entry to the market, whilst saving on development resource by introducing a volume competitive architecture from day one.
