the edx51 operating system

We have hosted the application the edx51 operating system in order to run this application in our online workstations with Wine or directly.

Quick description about the edx51 operating system:

The EdX51 operating system was designed as a teaching/learning tool. It provides operating system services to application programmers developing systems that run on 8051 microcontrollers and their derivatives. The OS was written in C using Keil�s �Vision IDE together with Keil�s C51 compiler.

Depending on the configuration, EdX51 uses between 632 and 1795 bytes of code memory.

The scheduler is cooperative and tasks have quasi-priority that is fixed at compile time. There is no task preemption. A task runs until it blocks. Once it blocks, the scheduler hands the CPU to the first ready task it finds in the list of tasks.

EdX51 provides a semaphore service, a message queue service and a watchdog timer service. These features can be easily removed if they are not required, thereby saving code and data memory.

Version 1.2.3 has had small mistakes in the documentation corrected. No changes were made to the EdX51 code.

Features:

• Embedded Systems OS
