%X Software Defined Radio (SDR) requires a reliable, fast and
   flexible method to chain parameterisable algorithms.
   Communicating Sequential Processes (CSP) is a design
   methodology, which offers exactly these properties. This
   paper explores the idea of using a Java implementation of
   CSP (JCSP) to model a flexible algorithm chain for Software
   Defined Radio. JCSP offers the opportunity to distribute
   algorithms on different processors in a multiprocessor
   environment, which gives a speed up and keeps the system
   flexible. If more processing power is required another
   processor can be added. In order to cope with the high data
   rate requirement of SDR, optimized data transfer schemes
   were developed. The goal was to increase the overall system
   efficiency by reducing the synchronisation overhead of a
   data transfer between two algorithms. To justify the use of
   CSP in SDR, a system incorporating CSP was compared with a
   conventional system, in single and multiprocessor
   environments.
