What does the future hold for DSPs? By Aneet Chopra, EVP Marketing & Product Management, XMOS

echnological advancement in any industry is always unpredictable. Seemingly ordinary devices are part of a dynamic market
that continuously evolves as designers reimagine, refine and reinvent their creations. Consequently, the systems under development must adapt to an increasingly broad array of inputs and signals. As new concepts emerge, and devices become more adept at interacting with the world around them – including us and each other, it’s crucial that the technologies are there to support that evolution. This becomes particularly crucial in
the age of the Internet of Things (IoT). From the factory floor to the smart city, we’re constantly creating products that

can intelligently and independently process data and perform tasks – which means they must flawlessly recognise and accurately respond to stimuli. This, in turn, means that some technologies must be able to span different sectors, devices and applications, to create something of a common language.
DSPs In modern-day life, most systems are becoming digital. To process analogue signals from the real world, first they must be turned into digital signals with the help of an array of devices such as analogue-to-digital converters (ADCs), microprocessors, and specific-type processors like digital signal processors (DSPs). They are all part of the analogue-to-digital chain of collecting and manipulating data that is initially
collected as analogue signals from the real world. DSPs run mathematical operations on this data, quickly and repeatedly. They create better signal interpretation, compression, modulation and equalisation. However, how will the DSPs change
in the era of electronics communicating with one another? Recently, the electronics market has
experienced a profound diversification. There was a time when semiconductor manufacturers would hedge their bets by dedicating the majority of their resources to developing ICs for a specific sector or application, like personal computers or digital cameras. But now, with the emergence of smart devices, there are also new market segments appearing, leading to a “market of niches”. Markets that used
