RI600V4 Real-time OS for RX Family

infoAdditional Details

Integrated Tools

• Compiler: CC-RX
• Integrated development environment: CS+、e² studio

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 RI600V4 Timer template file (PDF | English, 日本語) 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.

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.
