Real-time multitasking using ARM7 for elevator and camera with inbuilt embedded shell

Timed Multitasking for Real-Time Embedded Software

Software in real-time embedded systems differs fundamentally from its desktop or Internet counterparts. Embedded computing is not simply computation on small devices. In most control applications, for example, embedded software engages the physical world. It reacts to physical and user-interaction events, performs computation on limited and competing resources, and produces results that further...

Real-Time Destination-Call Elevator Group Control on Embedded Microcontrollers

We introduce new elevator group control algorithms that can be implemented to be real-time compliant on embedded microcontrollers. The algorithms operate a group of elevators in a destination call system, i. e., passengers specify the destination floor instead of the travel direction only. The aim is to achieve small waiting and travel times for the passengers. We provide evidence, using simula...

How to Use Real-Time Multitasking Kernels in Embedded Systems

A Mobile Phone- Embedded Real-Time Remote Video Surveillance System With Network Camera Using Arm

Monitoring facilities will be necessary and useful for our daily life, because it is very important for us to think about our security. This work developed an remote video surveillance system, which is organized with an integrated web server, network cameras, remote control devices and clients which connected to internet. Some kinds of devices can be used as our clients , for example, high-perf...

Embedded FIR filter design for real-time refocusing using a standard plenoptic video camera

A novel and low-cost embedded hardware architecture for real-time refocusing based on a standard plenoptic camera is presented in this study. The proposed layout design synthesizes refocusing slices directly from micro images by omitting the process for the commonly used sub-aperture extraction. Therefore, intellectual property cores, containing switch controlled Finite Impulse Response (FIR) f...
