MarketResearch.com’s new report “Q3 DSP Market Tracker” that adds to their cell phones market report collection states:
The DSP market has been thriving for some time now thanks to the mobile phone application market. Recently, the demand for smart phones that requires a microprocessor for the applications, has significantly limited the growth opportunities for DSP used in this space. Suppliers have responded to this by offering ARM Processors with integrated DSP function.
DSPs are used in many other application markets including wireless infrastructure, automotive navigation and imaging systems. This tracker provides demand statistics for DSPs. Sales of these products will reach close to $6 billion this year.
