Features

Microprocessor & SBC

Radstone Embedded Computing (Billerica, MA) released two versions of its 6U VPX form factor family, the DSP230 and the SBC610. Both are “AXISenabled” — they support Radstone’s AXIS Advanced Multiprocessor Integrated Software. VME interoperability is featured at the board level, allowing integration between the 6U VPX line and legacy VMEbus products.

Dual-Slot Controller

Linear Technology Corp. (Milpitas, CA) offers the LTC4242, a narrow, dual-slot PCI Express Hot Swap™ controller for mid-range networking or storage servers and embedded applications. The device simplifies the application by eliminating complex software interfaces, and allows for independently controlling the main supplies (12 V and 3.3 V) and the auxiliary (3.3 V AUX) supply on two slots.

Development Packages for M-Modules and PMCs

MEN Micro, Inc. (Ambler, PA) introduced the Universal Submodule (USM) development packages for M-Modules and PMCs that turn specialized I/O requirements into a series of standard products. The product implements a board’s desired functionality through one or more IP cores in an FPGA, augmenting the flexibility of M-Modules and PMCs with individual functionality. The same USM may be used on M-Modules, PMC modules, XMCs, and conduction- cooled PMC modules. Operating temperature is -40 to 85°C.

Data-Centric Network Integration Takes Headaches Out of Avionic Upgrades

Avionics systems are becoming more powerful and more dependent upon data exchanged between instruments. These instruments and subsystems reside on a network and must share time-critical data to achieve their mission. For example, targeting systems require real-time input of aircraft speed and attitude, as well as position and velocity data of the target. At the same time, additional bandwidth is required for data from onboard systems, such as GPS, airspeed and directional gyro, flight control systems, and dozens of other instruments and subsystems. As a result, network traffic is high, and potential data interactions can be highly complex. This complexity makes real-time integration of the data from disparate instruments during operational missions a significant challenge. Furthermore, upgrades of avionics and software applications during the useful life of the airframe means that new subsystems must be seamlessly integrated with legacy subsystems. In other words, data paths, interactions, and integration are not fixed forever. Today, aircraft systems typically are constructed to provide point-to-point communications between instruments and control systems that require realtime data. This approach has a significant impact on the complexity of the system and its subsequent maintainability. If an instrument is upgraded or replaced, the interfaces between it and other directly connected devices have the potential to change, requiring significant recoding and retesting.
