This product is a real-time operating system (real-time OS) that is an implementation of the μITRON4.0 specification. μITRON is the predominant real-time OS for embedded systems in Japan. Its low resource requirements, outstanding real-time performance, and broad range of service calls make it very suitable for embedded systems requiring true real-time and multi-tasking capabilities.

In addition, its high degree of compatibility with the compiler package from Renesas Electronics and multitasking debugging on the IDE will help you greatly reduce development times and get your products to market more quickly.

Functions

The HI7000/4 kernel consists of the following modules. Each module is provided by functions (service calls) .

  • Scheduler
    Manages execution sequence of multiple tasks based on their priority levels.
  • Task management
    Manages task status such as RUNNING, READY, WAITING or SUSPENDED.
  • Task-dependent synchronization
    Changes task status from other task, and synchronizes tasks.
  • Interrupt processing
    Returns from an interrupt handler
  • Time management
    Sets system timer used by HI7000/4 kernel and starts user-defined alarm handler, cyclic handler and overrun handler.
  • System State Management
    Reports information such as version number of HI7000/4 kernel.
  • Synchronization/communication
    Carries out synchronization and communication between tasks. The following function modules are available:
    • Event flag
      Tasks are synchronized by the status of flags managed by the kernel.
    • Semaphore
      Tasks are synchronized by the semaphore counter value managed by the kernel.
    • Mail box
      Tasks are synchronized by sending or receiving a message.
    • Data queue
      Tasks are synchronized by communicating 4-byte data.
  • Extended Synchronization/Communication
    Carries out synchronization and communication between tasks. The following function modules are available:
    • Message buffer
      Makes use of variable-length data communication to synchronize tasks.
    • Mutex
      Makes use of priority ceiling protocol for avoiding priority inversion to synchronize tasks.
  • Memory pool management
    Dynamically allocates/frees memory area used by tasks. Enables efficient use of memory.
  • Task exception
    Controls execution of task exceptions by, for example, defining or activating a task exception.
  • Cyclic handler function
    Controls the execution of a handler activated periodically.
  • Alarm handler function
    Controls the execution of a handler activated at the specified relative-time.
  • Overrun handler function
    Controls the execution of a handler activated when the specified time has been exceeded.
  • Extended service call function
    Renesas original functions are following:
    • Task event flags
      Makes use of task event flag state to synchronize tasks.
