CompactPCI Camera Link Frame Grabber

Active Silicon (Chelmsford, MA) has released the Phoenix D48CL-3CPCI32, a conduction-cooled, 3U CompactPCI Camera Link frame grabber. Designed for extremely rugged environments, the Phoenix operates in temperatures of -40 °C to +85 °C. The board is suitable for harsh environments found in industrial, military, and aerospace applications. The Phoenix D48CL-3CPCI32 utilizes rear panel I/O and supports the 32-bit/66MHz CompactPCI bus. The Camera Link interface encompasses dual Base/single Medium configurations, including PoCL cameras at 60MHz pixel clock rates.

Multi-I/O PMC

Aitech Defense Systems Inc. (Chatsworth, CA) offers a compact, multi-I/O PMC for I/O environments. The low-power, single-width M705 features up to five dual-channel, dual-redundant MIL-STD-1553B channels, 16 ARINC-429 receive channels and eight ARINC-429 transmit channels, up to six RS-232/422/485 serial channels and eight opto-isolated digital discrete input channels, all of which reduce the number of I/O cards when developing subsystems. Additional board options include an ARINC 708 Weather Radar interface contained as VHDL within the large onboard FPGA.

Oscilloscopes

Agilent Technologies Inc. (Santa Clara, CA) expanded its mixed-signal and digital-storage oscilloscope portfolio with 10 new models that comprise its InfiniiVision 7000 Series. The InfiniiVision 7000 Series offers bandwidths up to 1 GHz and delivers a deep memory waveform update rate of up to 100,000 waveforms per second. Each model is equipped with a 12.1-inch XGA LCD display and comes in a compact package that's just 7 inches deep and weighs 14 pounds. The increased display size helps users who need to display up to 20 channels simultaneously with serial protocol. The update rate is 5,000 times faster than any other available scope, and allows the user to view critical signal detail that other scopes might miss with their longer dead times.

FPGA-Based Communication Channel for Digital Signal Processor Chips

A method for networking, and a network of, digital signal processors (DSP) via at least one field-programmable gate array (FPGA) enables the simultaneous broadcast of data from a DSP to a number of DSPs. The apparatus comprises a host DSP, at least one FPGA in communication with the host DSP for receiving a digital signal from the host DSP, and at least one non-host DSP in communication with at least one FPGA for receiving the digital signal.

Applying Reconfigurable Computing to Acoustic Sensors Using FPGAs

A novel microsensor processing architecture allows a field-programmable gate array (FPGA) to act as a reprogrammable preprocessor or coprocessor to a general-purpose processor (GPP). The FPGA does most of the computationally complex pieces of the algorithm, while the GPP is lightly loaded, performing control, communications, and housekeeping tasks (Figure 1). The flexible architecture supports a wide range of low-power applications, while still being able to leverage emerging commercial technology.

Delta-Sigma UHF Digital Waveform Generator

A prototype Digital Waveform Generator (DWG) in the ultra-high-frequency (UHF) range uses Delta-Sigma (Δ−Σ) modulation techniques, which permit arbitrary and accurate waveform generation. The DWG meets the demanding and diverse waveform requirements of future radar applications, including linear-FM (LFM) and continuous wave (CW) signals. This DWG also allows for the generation of waveforms at other frequencies by up-conversion or down-conversion.

Network-Enabled Resource Devices

Network Enabled Resource Devices (NERDs) combine the most common electronic components used in robotic applications into a standard electronics box with "plug-n-play" capabilities. Risk reduction efforts, systems testing and integration, and modifying the functionality of evolving systems becomes greatly simplified by standardizing core hardware and software components; in many cases, minimal software modifications are required to adapt an existing NERD for an emergent application.

Software-Defined Radios for Urban and Indoor Navigation

Software-defined radios (SDRs) are being developed to provide positioning and communication (POSCOMM) services inside buildings and tunnels, under tree canopies, and in other environments in which local radio- communication systems are accessible but Global Positioning System (GPS) signals are not present or are degraded. These SDRs could be especially helpful for teams of first responders (e.g., firefighters), and military personnel operating in urban settings. These SDRs are capable of navigating by use of GPS signals and can switch over to time-of-arrival (TOA) pseudolite navigation when GPS signals become unavailable, provided that signals from suitably placed TOA pseudolite transmitter nodes are available.
