Micrium OS Introduction

At the heart of any embedded OS is a kernel, which provides vital task scheduling and multi-tasking services to ensure that the timing requirements of your application code can be met, even as you regularly update and expand that code with new features. Micrium OS is more than a kernel, though, providing a number of additional modules to help you meet your project’s needs. Here is a summary of the Micrium OS components:

Component		Description
Real-Time Kernel		A highly reliable foundation for your multi-task application code.
File System		A flexible implementation of the FAT file system with support for multiple types of storage device
USB Device		A full-featured stack for implementing the device side of the USB protocol, including class support for CDC, HID, and MSC, as well as a framework for vendor-defined classes.
USB Host		An embedded USB host stack with support for the MSC, HID, CDC, USB2Ser, and AOAP classes.
Network		A TCP/IP stack with support for IPv4 and IPv6, along with a number of popular application protocols.
