Digital Signal Processors (DSPs) are microprocessors whose architecture and instruction set are tailored to carry out computation-intensive tasks fast and efficiently. From their early days, about 20 years ago, DSPs have grown in importance to become the base of an ever-increasing number of mass market applications, particularly in the communications, image/video processing and control/data acquisition areas. Today, the entire wireless industry operates with DSP-enabled handsets and base stations. Other examples of DSP-based applications include digital cameras, medical instrumentation and motor control. As a side effect, constant improvement in DSP hardware has also fuelled digital signal processing research, contributing to advancements in fields such as multimedia signal processing and adaptive filter design. CERN has already taken advantage of this technology for several crucial systems, in the diagnostics, control and data acquisition sectors. Examples are tune and intensity measurements, power supply digital regulation and detector implementation in experiments. The seminar gives an overview on DSPs history, principles and use. This coverage is then revisited by examining existing operational DSP applications in the PS division, such as the AD intensity and tune measurement system. Some hints are finally given on possible future DSP implementations within PS.
