Test and Evaluation Uses of Heterogeneous Computing

T est and evaluation of current systems is a time-consuming process that reflects both the intricacies of the object of the test and the range of equipment, personnel, and environments required. Many argue that this process consumes far too much of the time that it takes to put new systems into the hands of the warfighters, and uses way too many resources without much obvious benefit for those in combat.

Gallium Nitride High-Power Electronics

Gallium nitride (GaN) high-power electronic (HPE) devices have the potential to outperform those made from 4H-silicon carbide (SiC), the polytype used for HPE devices, because it has a larger critical electric field, ξC, the field at which the device breaks down – 3.5 versus 2.5 MV/cm. This is due primarily to GaN’s larger energy gap, EG – 3.39 eV versus 3.25 eV. GaN also has a slightly larger electron mobility, μ – 930 versus 900 cm2/V·s.

Adapting ATCA Technology to Mil/Aero Applications

The military’s transition to Network-Centric Warfare (NCW) has created an enormous demand for improved networking and performance capabilities for ground mobile command and control applications. Military success now depends on the ability to communicate actionable information among command centers, troops in the field, UAVs and other military assets. Although new technologies are continually being developed to meet military demands, this transition to NCW has created new uses for existing technologies, a few of which have been used for many years in the commercial realm before making the move into military applications.

The Evolution of CompactPCI From Parallel to Serial I/O

The true worth of an industry standard is measured in its ability to stand the test of time. From the onset, the system configuration, hardware components, and integration strategy all need to be built upon the inherent principles of flexibility, modernization, and efficiency.

PCI Filter and Amplifier Module

Alligator Technologies (Costa Mesa, CA) has introduced the USBPGF-S1™, a USB controlled single channel programmable signal conditioning instrumentation amplifier and low pass filter. It can configure itself from power-up with changeable but non-volatile configuration and operates independently in both “Turn-Key” and host-computer-controlled scenarios. It is compatible with 12, 16, or 24-bit A/D devices, and allows the user to mix and match filter characteristics and independently select and program each module’s coupling (AC or DC), corner frequency, and gain steps up to x1000 in either single-ended or differential measurements.

Processing Platform

The Zynq™-7000 Extensible Processing Platform (EPP) devices from Xilinx (San Jose, CA) integrate an ARM® dual-core Cortex®-A9 MPCore™ processing system with NEON and Double Precision Floating Point engine. Each Zynq-7000 EPP includes L1 and L2 caches, memory controllers, and commonly used peripherals. The processing system boots at power-up and can run a variety of operating systems independent of the programmable logic. The processing system then configures the programmable logic on an as-needed basis.

DC-DC Switching Regulator

Aimtec (Montreal, Canada) has expanded its line of DC/DC switching regulators with the launch of two new series: AMSR1.5-78-NZ and AMSR2-78-NZ (AMSRx-78-NZ). Feature rich with pin-to-pin replacements of 78xx linear regulators, the AMSRx-78-NZ switching regulators provide highly regulated (±1%) output voltages ranging as low as 2.5 VDC up to 6 VDC. Maximum output currents of 1.5A or 2A are produced at efficiency rates of up to 93% that remain virtually constant over the entire input range. Low output ripple and noise (45mV p-p) make these robust converters ideal for noise sensitive applications.
