    • The invention relates to an apparatus and to a method for the distributed development of
      process programs of a distributed real-time system, in particular a comprehensive distributed real-time system, on a distributed development hardware, wherein a given task is divided up into a multiplicity of processes capable of running in parallel, the dependencies of which are represented in the form of a marked process graph, and wherein there is a functional process specifications for each process, and wherein a maximum number of instructions
      N
      WC
      is provided for each process. According to the invention, a maximum process duration
      d
      WCE on the target hardware is calculated for each process from
      N
      WC
      /L
      ZH .
      L
      ZH indicates the capability of the target hardware (in instructions/unit time), and the
      transmission time UD of the output data A (measured in bytes) from an upstream process to a downstream process of the target hardware is calculated from
      UD = A/L
      C .
      L
      C indicates the capability of the communication system (in bytes/unit time), and each process of the process graph is annotated with the process time
      d
      WCE thereof. Each edge of the process graph is annotated with the transmission time
      UD on the target hardware, and, starting from a starting time of a starting node, which for example is assigned the time
      t=0 , each mark of the process graph is allocated the time which is given by addition of the process times and transmission times on the path from the starting node as far as said mark. In the case of a plurality of paths leading to the same mark, the respectively highest time is chosen, and the development of a process program is carried out on the basis of the functional process specification and the times determined from the process graph, of the start mark and end mark of the process of a development system, independently of the development of each other process program.

    • The invention relates to a method for data transfer between cyclic tasks in a distributed real-time system at the correct time, which real-time system comprises a real-time communication system and a multiplicity of computer nodes, wherein a local real-time clock in each computer node is in sync with the global time, wherein all periodic trigger signals
      z
      i
      b for the beginning of a new cycle
      i are derived in each computer node simultaneously from the advance of the global time, these periodic trigger signals starting the tasks, and wherein a task reads the output data of the other tasks from local input memory areas to which the real-time communication system writes information, and wherein a task writes the result data from the current cycle to a local output memory area, which is associated with the real-time communication system, at an
      a priori determined individual production instant
      z
      i
      f before the end of a cycle, and wherein the schedules for the time-controlled real-time communication system are configured such that the result data for a task that are existent in the local output memory area are transported to the local input memory areas of the tasks requiring the data during the time interval z
