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 CS+ IDE and the configurator which automatically generates startup files will help you greatly reduce development times and get your products to market more quickly.
Important:This product is a separate product from RI850V4 V2.00.xx.
Features
- Conformance with the µITRON4.0 Specification
The design conforms with the µITRON4.0 Specification, which prescribes a representative OS architecture for embedded control. - Excellent portability
To support its execution in various environments, the RI850V4 is separated into the target-dependent section for hardware-dependent processing and the parts for use in the user’s own code. Sample files of source code are provided. This enhances portability to various execution environments and facilitates customization. - ROM-based implementation
Since the system is a real-time and multi-tasking OS designed on the assumption of usage in embedded execution environments, it was designed to be compact and ready for ROM-based implementation. A system can be configured with only those service calls that are actually used in the user’s application being linked (rather than all service calls provided by the RI850V4), so a real-time/multi-tasking OS which is optimally compact in terms of the user's needs can be configured. - Realization of memory savings
The ability to disable preemption provided by the RI850V4 can reduce a system's memory requirements. - Interlinking with the CS+ Integrated Development Environment from Renesas Electronics[Learn More]
- Automatic settings for options required in building the OS
- Displaying the states of OS control objects such as tasks, semaphores, etc. (Resource Information)
- Generates service calls to start up tasks from debugger, set up event flags, etc.
- Graphical display of the history of task operations and of issuing service calls (system performance analyzer)
- Interlinking with Green Hills Software, MULTI IDE from LLC[Learn More]
- Supported compiler: CC-RH, GHS
