ICDSP

As early as the 1950s, designers of signal processing systems used digital computers to simulate and test their designs. It was not too long to realize that the digital algorithms developed to drive the simulations could be used to carry out the signal processing directly. And so the digital signal processor was born. With the fast development of microprocessor chips over the last few decades, digital signal processing has become a hugely important topic. During the late 1980s and 1990s, virtual reality was also touted as a new and emerging application that promised to revolutionize interactivity and man-computer interfaces, which is older than or nearly as old as the computer graphics field itself.
