Overview

RTX51 Tiny is a real-time operating system (RTOS) which allows you to create applications that simultaneously perform multiple functions or tasks. This is often required in an embedded application. While it is certainly possible to create real-time programs without an RTOS (by executing one or more functions or tasks in a loop), there are numerous scheduling, maintenance, and timing issues that an RTOS like RTX51 Tiny can solve for you.

A real-time operating system (RTOS) allows flexible scheduling of system resources, like the CPU and memory, and offers communication between tasks. RTX51 Tiny is a powerful RTOS that is easy to use and that works with all 8051 derivatives.

RTX51 Tiny programs are written using standard C constructs and compiled with the Keil C51 C Compiler. Additions to the C language allow you to easily declare task functions without the need for complex stack and variable frame configuration. RTX51 Tiny programs require only that you include a special header file and link the RTX51 Tiny library into your program.
