A new Energy-Saving Real-Time Operating System for all embedded systems.

UTOS – a new Real-Time Operating System(RTOS). UTOS is an abbreviation of Upwind Technology Operating System. Architected as an Set-based RTOS, UTOS is highly customizable and adaptable, and can be easily configured to meet exacting application-specific requirements. UTOS has many features, including its set-based architecture, energy-saving, very small footprint and fast response.

Features of UTOS

Energy-Saving

UTOS reduced unnecessary function and machine instruction. UTOS doesn’t use lots of ROM/RAM resources and electric power.

Very Small Footprint

The minimal footprint of UTOS is under 300Byte ROM and 100Byte RAM on Microcontrollers.

Fast Response

UTOS is implemented in assembly language. It enables a highly optimized context switch.
