Multi-Fabric Switching Enables New Architectures for Military Systems

With multiple switched interconnects gaining momentum in the embedded space, selecting just one to address a wide range of military systems requirements is not easy.

Individually, switched fabrics such as Gigabit Ethernet (GbE), Serial RapidIO (SRIO), and PCI Express (PCIe) have their own particular technical merits, and each is poised to carve out a piece of the interconnect market. However, when combined in nextgeneration Serial Switched Backplanes (SSB) like VPX (VITA 46/48), multi-fabric switching can enable powerful new military architectures by leveraging 'best of breed' interconnect technology to address specific application requirements ( Figure 1).

Multicores Affect Algorithm Choices

Design engineers soon will need to bridge the growing gap between hardware reality and software capabilities in the highperformance computing (HPC) realm as the use of multicore microprocessors grows. If your software development or sourcing plans haven't anticipated these development situations, your applications may have a shorter life than you had planned.

The 2006 version of technical computing "reality" is an inexpensive dual-core processor from AMD or Intel on a desktop system, or a dual- or quad-core RISC processor from Sun or IBM running on a server. In 2007, we should expect to see inexpensive quad-core processors from AMD and Intel, and processors with up to eight or more cores in 2008. These small symmetric multiprocessing (SMP) systems will be a far cry from the proprietary $500,000+ SMP systems of a few years ago. This technology transition has big implications for the "democratization" of computing power. On the horizon are four- to eightcore systems that cost only a few thousand dollars and sit on the desk of every design engineer.

Track-and-Hold Amplifiers For Advanced Test Equipment

The GigaTrack™ family of 2-GS/s track-and-hold amplifiers (THA) from Inphi® Corp. (Westlake Village, CA) delivers ultra-wide 18-GHz analog bandwidth.

The bandwidth, sample rate, and linearity make direct conversion and software-defined receivers possible, and help advance highsample- rate test and measurement equipment. The GigaTrack amplifiers operate from a single -5.2 V power supply and dissipates 1.3 W. They are available in a 49-pin ceramic ball-grid array and in 24-pin QFN packages. The devices are designed for engineers designing next-generation instrumentation, ATE, and military equipment. They enable engineers to replace numerous components in heterodyne receiver architectures with a track-and-hold and a high-samplerate ADC. A direct conversion receiver can serve multiple applications with system differentiation occurring in software or firmware. The GigaTrack family consists of four track-and-hold amplifiers with 2-GS/s sample rates. The ball-grid-array versions offer 18-GHz (small signal) and 15-GHZ (0.5V pp) input analog bandwidths, with settling times >60 ps and power consumption of 1.3 W. Plastic QFN versions offer 13-GHz analog bandwidth (100mV pp).
