# Event Kernel

NOTE: Some of the material in this topic has been adapted with permission from CEVA documentation. This chapter is intended to complement the CEVA API documentation included with your RSL15 install.

The RSL15 event kernel is a small and efficient event and message handling system that can be used as a Real Time Operating System (RTOS) or as a process executed under an RTOS, offering the following features:

- Exchange of messages
- Message saving
- Timer functionality
- The kernel also provides an event functionality used to defer actions

The purpose of the event kernel is to provide messages (such as the ones in Messages) and timed tasks to keep RF traffic on schedule and aligned with the specification requirements.
