RTOS Choices for Medical Devices

In the design of a medical device or system that relies on embedded computing capability, engineers in this highly regulated industry very often choose the operating system first, and most often a real-time OS is selected. But how to arrive at the correct choice of RTOS can be tricky, especially as the architecture of the OS has an effect on a system’s reliability and ability to recover from faults. This tutorial article provides on overview of RTOS choices and a roadmap to selecting the right one for various types of medical device applications.

Proposed Vehicle Safety Regulations Demand Rear Cameras and Displays
CAP Wireless, Inc.

With the federal government's proposed new vehicle safety regulation calling for standard rear-mounted video cameras and in-vehicle displays to prevent backup accidents, manufacturers are looking for smaller, cost-efficient ways to incorporate the features into all models. Such camera systems require robust, uncompressed digital video links to deliver high-resolution data and enable signal processing. National's FPD-Link III embedded clock SerDes with ultra-low EMI signaling integrate data, clock, and real-time control over a single twisted wire pair.

Secure FPGA Brings SWaP-C Savings to UAVs

{sec1_editem1_img1_alt} Model-airplane-sized UAVs provide stealthy, real-time intelligence, reconnaissance and surveillance capabilities to troops and commanders in the field. The data exchange between the unmanned aerial vehicle and its ground control station must be made secure via Type 1 encryption. This single-chip crypto (SCC) design implemented in an FPGA protects communications, safeguarding telemetry, video, and control data while providing size, weight, power and cost (SWaP-C) savings.

SoC for Wireless Set-Top Box

{sec1_editem1_img1_alt} Broadcom offers this system-on-a-chip solution for set-top boxes and says it is the first to integrate the Microsoft® Mediaroom wireless client. OEMs using the company’s earlier SoC for STBs in combination with the new chip can now offer system operators the ability to bring IPTV to customers wirelessly as well as remove the necessity to have multiple boxes on a wired network. Who knows? This could make visits from the cable guy a lot shorter.

Server Board for Systems that Never Sleep

{sec1_editem1_img1_alt} Advantech has introduced a dual-processor server board intended for mission-critical embedded applications requiring round-the-clock uptime. Based on dual Intel® Xeon® 5500/5560 series processors, the board fits applications in medical imaging, industrial control and automation equipment, digital surveillance, and military simulators.

TI First to Incorporate EtherCAT Industrial Protocol

{sec1_editem1_img1_alt} In a move that many observers believe will move EtherCAT (Ethernet for Control Automation Technology) beyond factory automation applications, Texas Instruments becomes the first semiconductor company to license the industrial networking protocol for its lines of embedded processors. The advantages to be gained by end-users, integrators and TI are enumerated here.

Rapid Wireless Network Growth in Embedded Applications

{sec1_editem1_img1_alt} VDC Research sees very healthy growth for wireline industrial networks through 2015. But in its latest reports, the firm also states that improvements in technology and the establishment of robust standards will propel the family of 802.11 wireless networks into an increasingly prominent role. Narrow-band proprietary schemes will continue to lose ground as new systems and upgrades of existing systems go the 802.11 route.

Secure Your Embedded Network

{sec1_editem1_img1_alt} Mission-critical embedded networks must be secure in all respects. But writing code to take advantage of the security capabilities of network protocols can be an intimidating and time-consuming job for the embedded system developer. This primer on network security for embedded system developers lays the groundwork for simplifying the task and managing security issues in general.
