Are You Using More Than One Software Analysis Tool?
Actually, a better question for many embedded developers is whether they’re using even one code analysis tool. In many cases, the number of static or dynamic analysis tools used by a programmer is zero. At the same time, the goal that seems to be on top of everyone’s list is getting bug-free software done on time. Unfortunately, this can be a challenge when you aren’t using these tools. Most developers know that finding and fixing bugs early is less...
The Latest Static And Dynamic Analysis Tools
Designers can take advantage of a host of new static and dynamic code analysis tools from different vendors. Coverity has a range of static and dynamic analysis tools, but its Coverity Build Analysis addresses an aspect that is key to the development process but often overlooked—the build process. It helps Coverity stand out from the pack in addition to helping prevent bugs in the build process by identifying issues such as using the wrong object...
Flash Storage Device Delivers 300k Ops/s Using DDR2 RAM
Untitled Document Looking for some really fast nonvolatile storage? DDRdrive delivers doubledata- rate (DDR) performance with NAND nonvolatility. Its DDRdrive X1 adds an FPGA between a PCI Express Gen 1...
Chip Links PCI Express And USB
The OXPCIe200 PCI Express (PCIe) bridge links a 1x PCI Express host to a pair of USB host interfaces or one USB host interface and an SPI/SRAM interface (see the figure). The bridge also provides access to a serial port and eight generalpurpose I/Os (GPIOs). The bridge’s dual-USB mode provides one high-speed and one full-speed USB 2.0 host interface. The high-speed interface has a...
Common-Law Accelerator Offloads DSP
Adding a Control Law Accelerator (CLA) to Texas Instruments’ line of C28x DSPs can boost performance in applications such as motor control, LED lighting, and digital power by a factor of five. This allows the TMS- 320F2803x chip to handle more demanding applications or deliver high performance with lower power requirements. The F2803x family’s C28x DSP core delivers 60 MIPS. Compared to the F2802x, the newer siblings provide peripheral ...
NAND Delivers Capacity And NOR Capabilities
Samsung’s Flex One NAND has moved to 40 nm. It combines multi-level cell (MLC) and single-level cell (SLC) flash with an SRAM front end providing NOR functionality, including the ability to run applications directly. The Flex One uses a 2-kbyte SRAM cache to implement SLC flash. Designers can configure the flash memory split into SLC (code and data) and MLC (data) partitions. MLC storage density is twice the 1-bit/cell total for the SLC...
10GE Controller Transforms Data Centers With Virtualized I/O And Unified Networking
The 82599 10-Gbit/s dual-port Ethernet controller from Intel is designed to address some of the trends driving datacenter upgrades. For example, it includes hardware optimization for I/O virtualization and supports unified networking, allowing local-area network (LAN), storage-area network (SAN), and Internet Protocol communications (IPC) traffic to share the same Ethernet network. With data-center traffic continuing to grow, IT departments ...
Embedded USB Tower Of Babel
Do you speak USB? If so, then you’re using one or more of the USB classes shown in the table. The most popular classes tend to be the human interface device (HID) and the mass storage device, since these kinds of products are ubiquitous around PCs and mobile devices like digital cameras. Details can be found at the USB Implementers Forum. The class approach works well by allowing device driver and...
Thanks For The Memory
Every processor needs storage. A few systems may get by with a single type, but more often a hierarchy of technologies is employed, such as a server with a redundant array of disks (RAID) storage system (Fig. 1). Each component brings something to the system, be it high capacity, fast access, or nonvolatility. The mix is changing, too, as new technologies come online and existing technologies change...
Apply Virtualization To Storage I/O
Virtualization is receiving lots of attention these days. Behind the buzz are some simple, time-tested concepts. But the movement of this technology from the mainframe to the mainstream has brought it into the limelight. At its heart, virtualization is about making something “look” like something else. Typically, this means making an operating system “think” it’s running alone on a computer, when in fact that computer is shared by several...
Overcome Barriers To Broad-Based SSD Adoption In The Enterprise
At first glance, solid-state drives (SSDs) appear to be a no-brainer for makers of storage systems for enterprise servers and laptops. After all, SSDs promise higher read/write performance, higher reliability, and lower power consumption compared to hard-disk drives (HDDs). But in practice, SSD adoption has been held back not only by a higher cost per gigabyte, but also by real-world issues that prevent them from achieving their performance and reliability...
The Indianapolis 500 Electronic Edge
Surely most racing fans have May 24, 2009, circled on their calendars. For the non-gearheads, this Memorial Day marks the 93rd running of the Indianapolis 500. The event will pit 33 cars and drivers against each other in a grueling 500-mile race around a 2.5-mile track. The fastest average speed is more than 185 mph with top speeds cresting at about 235 mph. The front and back straightaways are only five-eighths of a mile long, so drivers spend a good deal of...
A Zoom Lens Improves Photos As Well As Vision Systems
The lens and the capture electronics are the two most critical pieces of a vision system. Skimp on either, and the results are sub-par. Going with a fixed glass lens often improves quality over a plastic lens, but an adjustable zoom lens provides more options without having to move the camera. This is handy in taking photographs, but it can be useful in a range of other imaging applications as well, including robotics. Adding a built-in zoom lens to...
Module Makes High Speed USB Easy
Need a High Speed USB serial link? Then check out DLP Designâ??s module based on the latest chip from Future Technology Devices International (FTDI). The DLP-USB1232H has a standard 18-pin dual-inline package (DIP) form factor. The FTDI FT2232H is designed to handle the 480-Mbit/s High Speed USB specification, allowing the system to handle transfers up to 12 Mbaud, essentially being limited by the RS-232 transfer rate. The chip can handle bulk...
