Design of Embedded WEB Remote Monitoring System Based on μC/OS-II Operating System

Isolating embedded system has not been adapted to current development tendency. More and more embedded systems need networking for communicating with each other. μC/OS-II, which is a typical embedded real time operating system and contains a kernel without network protocol, has been widely used in a large number of embedded systems. So it is of significance to join network protocol into μC/OS-I...

8051 NET - ISP : Internet - Based Remote Programmable Embedded Micro - Controller System

Two general schemes of programming a microcontroller unit (MCU) are integrated-circuit burner-based and in-system programming (ISP) methods. The former requires a physical contact with MCUs, whereas the latter requires MCUs containing universal asynchronous receiver-transmitter (UART) or universal serial bus (USB) interfaces. This study proposes an Internet-based remote programming system, name...

The RC5 Encryption Algorithm

This document describes the RC5 encryption algorithm, a fast symmetric block cipher suitable for hardware or software implementations. A novel feature of RC5 is the heavy use of data-dependent rotations. RC5 has a variable word size, a variable number of rounds, and a variable-length secret key. The encryption and decryption algorithms are exceptionally simple.

Vision-based fuzzy 8051 surveillance systems design

This paper proposes a vision-based fuzzy 8051 surveillance system which emphasizes on designing the image processing function to detect the invaded states and the 8051 fuzzy servomotors controller to track the invader region. The techniques include discrete wavelet transformation (DWT) image data reducing, edge detection, motion detection, and fuzzy servomotor control. In this paper, image proc...
