Synchronizing Mechatronic Systems in Real Time Using FGPAs and Industrial Ethernet Communications
By Ethernet POWERLINK Standardization Group, B&R Industrial Automation Group, and Altera
Read about major Industrial Ethernet communications protocols in use today, and an example implementation of an open source protocol implemented on an FPGA.
Signal Filtering
SpaceVPX adds fault tolerance, cuts cost for space-bound HPEC systems
By Brandon Lewis, Assistant Managing Editor
Reliability and fault tolerance combine in a new, high-performance embedded computing open standard called SpaceVPX that is aimed at the space electronics industry.
Optical Revolution
Optical data links could be in your (very near) future
By Ray Alderman, VITA
Very soon, we will hit the bandwidth limit of serial links on copper and be forced to move to optical. How close are we?
Integration Issues
If wishes were fishes - An accidental computer scientist goes embedded
By Mark Honman, Sundance Multiprocessor Technology, Ltd.
Is it even still relevant to discuss the topic of integrating DSP and FPGA devices in the same hardware?
Sensor Fusion Focus
Basics of 6DOF and 9DOF sensor fusion
By Jacques Trichet, Freescale Semiconductor
Inertial and magnetic sensors are becoming quite pervasive. When driving our cars or as simple pedestrians, most of us would have a hard time finding our way around without the navigation applications they support. Our smartphones rely on electronic compasses (eCompasses) built on inertial and magnetic sensor technology to determine direction, and with the help of GPS and maps, guide us blindly through the urban maze.
Programming and Programmable Logic
Signal processing FPGAs with hard floating-point - No compromise
By Jeff Milrod, Bittware
Since the dissolution of cutting-edge digital signal processor (DSP) product lines designers have been forced to develop using either FPGAs integrated with time-consuming fixed-point DSP blocks, or floating-point general-purpose graphics processing units (GPGPUs) that leave performance on the table in high-end signal processing systems. But now, with the release of Altera's Generation 10 FPGAs that integrate hardened IEEE 754-compliant floating-point operators, why compromise?
Programming and Programmable Logic
Designing a 2 million-point frequency domain filter using OpenCL for FPGA
By Dmitry Denisenko and Mykhailo Popryaga, Altera Corporation
Fast Fourier transform (FFT) is the backbone of signal processing applications. For a long time now, FPGA vendors have been providing well-tuned FFT libraries to process data sets that fit in FPGA on-chip memory. But what do you do if your data set is too large? To solve this problem, the FPGA designer must now make multiple intertwined design decisions, such as considering on-chip FFT core configuration options, how many to include, how they connect and access external memory, synchronization among multiple cores, and many others. Exploring all such design decisions to create the perfect combination for the product at hand while coding in HDL is just too time-consuming and can actually leave performance on the table. With a higher level programming language such as OpenCL, however, system design exploration can be done in days.
Automotive Radar for Active Safety
Design of FMCW radars for active safety applications
By John Zhao, Marco Roggero, and Giorgia Zucchelli, MathWorks
Car manufacturers, automotive electronics suppliers, and universities are working to develop new electronic systems for advanced driver assistance systems (ADAS). Frequency-modulated continuous waveform (FMCW) radars fit the requirements of automotive active safety systems because of their accurate short-range measurements, low sensitivity to clutter, and easy integration. FMCW radars are widely used as a component of ADAS systems in the automotive industry.
Signal Processing
MicroTCA.4 continues culture of COTS signal processing at DESY
Interview with Holger Schlarb and Michael Fenner, DESY
In this interview with engineers in the Machine Beam Controls Group at DESY, Holger Schlarb and Michael Fenner discuss the data acquisition requirements of the accelerator community, as well as how a tradition of using COTS signal processing solutions continues to improve uptime and maximize performance for some of the most complex machines on Earth.
HPC General-Purpose Processors
Edge-based analytics using general-purpose processors
By Nigel Forrester, Concurrent Technologies
Increasing demand for bandwidth at the network edge is driving the need for easily programmable, low-cost signal processing systems that can scale as data volumes grow. This is leading to the deployment of general-purpose processors in domains traditionally occupied by digital signal processor (DSP) and FPGA devices, with off-the-shelf module vendors innovating on low-latency interconnect architectures and middleware solutions that unlock the value of commercial processors in the mobile and machine-to-machine (M2M) era.
