The RI850V4 V2.xx.xx consists of the following modules.

(1) Kernel

The kernel, which is the processing block that forms the core of the RI850V4 V2.xx.xx and the main processing block for the service calls provided by the RI850V4, provides the following functions.

- Task management functions

- Task dependent synchronization functions

- Synchronization and communication functions (Semaphores, eventflags, data queues, mailboxes)

- Extended synchronization and communication functions (Mutexes)

- Memory pool management functions (Fixed-sized memory pools, variable-sized memory pools)

- Time management functions

- System state management functions

- Interrupt management functions

- Service call management functions

- System configuration management functions

- Scheduler

- System initialization functions

(2) User-own coding module

To support various execution environments, the RI850V4 V2.xx.xx extracts hardware-dependent processing that is required to execute processing as user-own coding modules, and provides it as sample source files. This enhances portability for various execution environments and facilitates customization as well.

The following lists the user-own coding modules extracted for each function.

- Task management functions (Post-stack overflow processing)

- Interrupt management functions (Interrupt entry processing)

- System configuration management functions (CPU exception entry processing, initialization routine)

- Scheduler (Idle routine)

- System initialization routine (Boot processing)

- System initialization routine (System dependent information)
