The world of Automated Video Surveillance
Automated Video Surveillance systems seek to automatically identify people, objects, or events of interest in variety of environments. Typically, these systems consist of stationary cameras directed at borders, airports, sea ports, offices, parking lots, and so on. The core of these applications is real-time motion detection and tracking algorithms, which provide low-level functionality for building higher level recognition capabilities Read more...

Partner Showcase Hit performance goals with configurable processors With mainstream DSPs, code must be hand-tuned using assembly code in order to meet performance goals. A more productive approach is to tailor the processor to the algorithm. This article explains why, using FFT, Viterbi, and MPEG4 examples Read More... - By Steven Leibson, Tensilica

1. Making the MOST
Back in the day, FPGA designers were a determined bunch. They had to be. They needed the special advantages of FPGA technology so badly that they would practically walk across hot coals to get the darn things to work. Today, however, designers have two things that those engineers did not – schedule pressure, and options Read More...

2. Optimizing C programs for embedded SoC applications
Program developers of embedded processor cores within System-onChips (SoCs) want their code to run fast to lessen processor-operating frequency, consume little memory and reduce memory cost. Two key factors affecting the design team’s ability to meet such goals are the compiler’s code-optimizing efficiency and source-code programming styles Read More...

3. How to design FPGA-based advanced PCI Express endpoint solutions
Currently dominating the desktop PC motherboard and graphics markets, the PCI Express protocol is poised to supplant PCI and PCI-X interface as the dominant high-bandwidth interconnect for the server, enterprise, mobile, workstation, networking, communications, industrial control, and medical equipment markets Read More...

4. Interrupt Management Under Linux: Using the Interrupt Controller API
Interrupt handling is a fundamental part of the Linux kernel. Most of the kernel's functionality, in particular the parts of interest to embedded developers, in some way involve interrupt handling. This article describes the most important concepts related to the Linux kernel's interrupt handling mechanisms that include the relevant code and data structures Read More...

5. Designing An ARM-Based Multithreaded Audio/Visual/Motion Recording System
Although it is a generic case study design - not an actual implementation - a real time video/ audio/ motion (VAM) recording system highlights a number of key operating system features and services that must be considered in any embedded system design, including: application timers, threads, message queues, mutexes, memory byte pools Read More...
