The PRISM 2.2 real time signal processing system

A description is given of the PRISM 2.2 system, a general purpose real-time signal processing system designed for very easy development and modification of signal processing applications. Both the hardware and software are flexible and easily modified to support changing project requirements. Use of additional hardware requires only an update of the configuration file. Signal processing block diagrams are easily converted to the PRISM script language which maps the processing to the hardware specified in the configuration file. Changes to processing usually require only changes to the script. Code changes are not necessary unless the project requires functionality not provided by the current tool set. Standard interfaces also exist for getting input data into the system and for getting results and display data out of the system
