It is argued that high speed, flexibility, and good arithmetic abilities make digital signal processors (DSP) a good choice as input/output controllers for real time applications. The DSP can be made to preprocess data in real-time to reduce data volume, to open early windows on what is being acquired, and to implement local servo loops. An example of a DSP as an input/output controller for a digital subtraction angiographic imaging system is presented. The DSP preprocesses the raw data, reducing data volume by a factor of two, and is potentially capable of producing real-time subtracted images for immediate display
