%T CSP and Real\-Time: Reality or Illusion? %A Bojan Orlic, Jan F. Broenink %E Alistair A. McEwan, Steve Schneider, Wilson Ifill, Peter H. Welch %B Communicating Process Architectures 2007 %X This paper deals with the applicability of CSP in general and SystemCSP, as a notation and design methodology based on CSP, in particular in the application area of real\-time systems. The paper extends SystemCSP by introducing time\-related operators as a way to specify time properties. Since SystemCSP aims to be used in practice of real\-time systems development, achieving real\-time in practice is also addressed. The mismatch between the classical scheduling theories and CSP paradigm is explored. Some practical ways to deal with this mismatch are presented.
