productroundup Code analysis visualisation GrammaTech’s CodeSonar software-analysis tool has acquired extended software architecture visualisation features, including a new treemap view designed to allow users to see the hierarchical structure of the code in a very information dense form. The view colour-codes density of defects in modules to highlight the most problematic parts of the code. The call graph is organised by module structure. Users can drill down to see a greater level of detail, choose different layouts such as treemap, circuit, cluster, flow, radial and other layouts, and attach persistent notes to the diagram. Transitions such as zooming or layout changes are fluid and real-time. Users can start at individual functions to gain insight from a bottom-up perspective, annotate nodes and edges with additional information and, overlay the visualisation with information on defects and source-code metrics. GrammaTech, www.grammatech.com Dual-core A9 image processor Under the branding “Visconti 3” Toshiba has added a line of image-recognition processors for automotive use, targeting functions such as recognition of traffic lanes, vehicles, pedestrians, and traffic signs using integrated image processing accelerators that detect pedestrians with high level detection ratio, in real time. The first device in the series, TMPV7528XBG, incorporates an ARM 32-bit Cortex-A9 MPCore in dual-core configuration, for applications-interfacing with the image recognition processor. To optimise image recognition algorithms that analyse large volumes of image data from the video source, frame-by-frame, in real time, but with limited power consumption and memory resources, Toshiba has configured the Cortex-A9 cores with a single/double-precision FPU in each core. Also on-chip is a Toshiba 32-bit RISC CPU; a media embedded processor (MeP); four instances of Toshiba’s multi-core media processor Media Processing Engine (MPE); and hardware accelerators for specific functions. Toshiba Electronics Europe, www.toshiba-components.com AMD G-Series embedded PC For industrial and embedded computing applications, MEN’s BC50I uses an AMD Embedded G-Series Dual Core G-T48N APU, features two Gigabit Ethernet ports, two USB 2.0 ports and two DisplayPorts. It supports a wide range of communications standards and includes “legacy” serial communications, as well as an optional CAN bus connection. It is conduction cooled and rated for operation over -40 to +70°C. Processor core frequency is 1.4 GHz, and other AMD Embedded G-Series can be selected for alternative processing power points. The DisplayPorts with a maximum resolution of 2560x1600 pixels each deliver HD quality. The BC50I has a 16 to 36 V wide-range power supply and costs €995 (single unit). MEN, www.men.de/09BC50I.html 1200V, 225°C SiC MOSFET CHT-Neptune is a high-voltage silicon carbide power switch in a TO-257 package, suitable for power converters and motor drives and guaranteed for reliable operation up to +225°C. The package has junction-to-case thermal resistance of 1.1°C/W; the device has a breakdown voltage in excess of 1200V and will switch currents up to 10A at the maximum temperature (Tj=225°C). The device features a body diode that can be used as free-wheeling diode. The switch can be controlled with a typical gate voltage (VGS) of -2V / +20V. The transistor’s RDS-ON is 90mΩ at 25°C and 150mΩ at 225°C with VGS=20V. Support and characterisation data can also be provided to drive the transistor at lower VGS voltages (e.g. 5V or 10V). This new device features low - and temperature-independent - switching energy of less than 400μJ at 600V/10A. Pricing is €287.38 (51 – 200). Cissoid, www.cissoid.com Ultra-low noise regulators The PS2292X series are robust linear regulator products built in a bipolar process for low noise performance and very low dropout (LDO) current. The devices are part of a high current, single supply, LDO family that operates from an input voltage as low as 1.7V and as high as 12V, for use in low voltage, post regulation applications. They have fast transient response while maintaining high Power Supply Rejection Ratio (PSRR). Other fea 42 EDN Europe | MARCH 2013 www.edn-europe.com
