RTX51 Introduction

The RTX51 executive is a real time kernel for the 8051 microcontroller family. Placed in the heart of an application, it provides efficient task scheduling by driving:

  task activation: initiate, waiting or stop.

  task relationships.

RTX51 is easy to implement and permits the programmer to concentrate on each task, independently from the remaining application. RTX51 recognizes tasks written indifferently in assembly, PL/M-51 or C-51 language and provides support for any compatible derivatives of 8051, except 83C751 and 83C752.

RTX51 consists of two parts:

  the scheduler which is the task scheduling program.

  the services or functions that can be called by tasks to send various requests to the scheduler.
