4. THINGS TO CONSIDER FOR DEVELOPING
AN OPERATING SYSTEM
•
•
•
•
RTOS architecture to be considered.
Language support
Tool capabilities
Services that are provided for the developers though
API’s
• Technical support for the users

5. RTOS FOR SMALL
MICROCONTROLLERS
• Why do we need RTOS for small Microcontrollers
• Small Microcontroller refers to Maximum ROM
of 128Kbytes and 4Kbytes of RAM
• Using for Software Optimization - low power –
high performance.
• RTOS can be used to distribute software
development among the developers
• Software synchronization

6. RTOS FOR SMALL
MICROCONTROLLERS
• The use of the RTOS in small Microcontrollers have
increased considerably
