RI600V4 Real-time OS for RX Family

This product is a real-time operating system (Real-time OS) conforming to the µITRON4.0 Specification, the predominant Real-time OS for embedded systems in Japan. Its compact resources, outstanding real-time features, and many service calls are suited for an embedded system with real-time ability and multi-tasking functions. In addition, its affinity for the IDE CS+ and e2 studio, and the configurator which automatically generates startup files will help you greatly reduce development time and get to market faster.

Note: RI600V4 is not generally promoted to U.S. and European customers. Customers in U.S. and Europe who are interested in RI600V4 are requested to contact our regional marketing departments for details.

Funcionalidades

  • Compliant with µITRON4.0 Specification
    The design conforms to the µITRON4.0 Specification, the representative OS architecture for embedded control.
  • ROM-based implementation:
    Since the system is a real-time/multi-tasking OS assumed to be used embedded in the execution environment, it was designed to be compact and ready for ROM-based implementations. Also, because the system can be configured linking only the service calls used in the system by the user (rather than all the service calls provided by the RI600V4), a real-time/multi-tasking OS can be configured which is compact and optimized for the user's needs.
  • Interface with CS+ and e2 studio, the Renesas Electronics Integrated Development Environment
    The RI600V4 OS interfaces with CS+ and e2 studio to support the following functions:
    • Auto-settings for options required in OS build
    • Displays state of OS control object for tasks, semaphore, etc. (Resource Information)
    • Graphical display of task operation logs and service call issue logs (Task Analyzer).
  • Sample Projects (CS+ edition) Provided for FIT
    Sample projects (CS+ edition) for the use of Firmware Integration Technology (FIT) with the RI600V4 real-time operating systems (Real-time OS) for the RX family are supplied.
    Download the sample project for FIT from Downloads Tab.

 

 

Functions

The RI600V4 kernel consists of the following modules. Each module is provided by functions (service calls) .

  • Task management functions
    Provided by the RI600V4 include a function to reference task statuses such as priorities and detailed task information, in addition to a function to manipulate task statuses such as activation and termination of tasks.

  • Task dependent synchronization functions
    Changes task status from other task, and synchronizes tasks.

  • Synchronization and communication functions
    The synchronization and communication functions of the RI600V4 consist of Semaphores, Eventflags, Data Queues, Mailboxes, Mutex, and Message buffer that are provided as means for realizing exclusive control, queuing, and communication among tasks.
    • Semaphores:
      In the RI600V4, semaphores are provided as a means (exclusive control function) for preventing contention for limited resources (hardware devices, library function, etc.) arising from the required conditions of simultaneously running tasks.
    • Eventflags:
      Provides 32-bit eventflags as a queuing function for tasks.Data Queues:
      Provides the data queues that have the data queue area in which data read/write is enabled for transferring the prescribed size(4 bytes) of data.
    • Mailboxes:
      Provides a mailbox, as a communication function between tasks, that hands over the execution result of a given processing program to another processing program.
    • Mutex
      An object to perform exclusive control, and providing support for the feature to avoid priority inversion problems.
    • Message buffer
      An object to communicate an arbitrary-length message by copying.

  • Fixed-sized memory pool
    A function to dynamically allocate/free memory of preassign fixed size.

  • Variable-sized memory pool
    A function to dynamically allocate/free memory of arbitrary size.

  • Time management functions
    Provides methods to implement time-related processing (Timer Operations: Delayed task wakeup, Timeout, Cyclic handlers, and Alarm handlers) by using base clock timer interrupts that occur at constant intervals, as well as a function to manipulate and reference the system time. When using the time management function, it is necessary to specify the timer template file corresponding to the target device in the system configuration file.

  • System state management
    Provides functions for referencing the system status such as the context type and CPU lock status, as well as functions for manipulating the system status such as ready queue rotation, scheduler activation, or the like.

  • Interrupt processing
    Provides functions about interrupt handler that is called when an interrupt is occurred.

  • System configuration management
    Reports information such as version number of RI600V4 kernel.

  • Object reset function
    Initializes the Data queue, Mail box, Message buffer, Fixed-sized memory pool, Variable-sized memory pool. This function is unique to the RI600V4 and is not defined in the µITRON4.0 specifications.

About Trial

We provide a trial software of the RI600V4 so that you can try out the functions and performance of RI600V4 before purchasing it. No support, including responses to inquiries through contact points, is provided for the trial software. Please accept this before using the trial software. In addition, please read through the Software User License Agreement (PDF) and following notes before downloading.

 

Before Downloading


 

[Cautionary Notes]

1.Difference with the Product Version

Although the performance and functionality are the same as the product version, the trial software has the restrictions described below.

 

Restrictions:
The RI600V4 real-time OS is forcibly shut down after running for an hour.
When the OS is shut down, the program jumps to the system down routine "_RI_sys_dwn__".
At this time, -64(0xffffffc0) is passed to the first argument, "type", of "_RI_sys_dwn__".

 

2.Using the OS for Finished Products

If you intend to embed the RI600V4 real-time OS in a finished product, use the product version. We do not offer any technical support services in case of troubles by using trial software.

 

3.Prohibition of Redistribution

Redistribution of the software tool to third parties is strictly prohibited.

 

[Operating Environment]

The operating environment is same as the product version. Refer to Operating Environments of Products.
