[Technology Report]
Reconfgurable Architectures Chart A New Course For DSPs
Ever-increasing computational complexity and evolving wireless and consumer standards are forcing developers of monolithic digital signal processing (DSP) chips to look beyond the traditional fixed architectures that have served the industry...  — Ashok Bindra

[Product Innovation]
Tool Makes Sure I/O Designs Measure Up To Spec
Standing as they do as the bridge between the digital and mixed-signal world of System-On-A-Chip (SOC) cores and the largely analog world of the circuit board, I/O cells are an increasingly difficult beast for designers to tame. Not only must I/Os...  — David Maliniak

[Design Application]
DDR FIFOs Deliver The Goods For Advanced Networking
FIFOs definitely play an integral and important role in a diverse range of challenging applications, such as storage-area networks (SANs) and networking routers. To keep pace with these fast-moving markets and meet new performance requirements, FIFO...  — Stefan Schoettl , et al.

[Ideas For Design]
Speed Control Handles Isolated –48-V Fans
Chips are available to monitor and control ventilation fans. But less common are fan controllers for telecom applications. Such fans must operate in electrically isolated environments with a supply voltage in the 36- to 72-V range. For example, the...  — Jim Christensen

[Ideas For Design]
Eliminate Latching Current limit In Power Supplies
Most modern power-supply control ICs offer built-in overcurrent or short-circuit protection. While some overcurrent-protection schemes are latching, others are nonlatching. When the overcurrent trip level is reached in a latching controller, the...  — Michael Day

[Ideas For Design]
AC Motor Driver Features PC Programmability
A simple PC-programmable ac motor driver is easily implemented using one FIFO, simple logic, and power drivers. Figure 1 shows the basic block diagram of the circuit. It generates three sinusoidal voltage...  — Massimo Gottardi

[Editorial]
E-Mail Spam: Enough Is Enough! The Time For Action Is Now!
I don't know how they do it, but spammers offering everything from new credit cards to mortgages to pleasure-enhancing products manage to find their way into my e-mail inbox. This invasion has morphed my mood from one of amusement to one of...  — Dave Bursky

[Pease Porridge]
What's All This Knot Stuff, Anyhow? (Part III—The Dutchman)
A long time ago, my father showed me how he tied a "Dutchman," a specialized knot used by truckers in the 1940s and '50s to tie a load onto a truck. But he never really taught it to me, so I didn't really learn it. More recently, I decided that I...  — Bob Pease

[Viewpoint]
Neglecting IR Drop In Nanometer Designs Leads To Silicon Failure
In the move to higher clock rates and advanced process technologies, designers find increasing silicon failure in designs that appear to pass verification signoff. Today, many problems can be traced to complex electrical and physical effects that...  — Simon Young

[Editor's Notebook]
The Move To Serial Bus Interfaces Promises Pin-Count Reductions
It seems that no matter which system-design conference you attend, there will be a session or two on serial buses that promise to eradicate wide parallel buses and other interconnections. Such buses are commonly found on connector backplanes, as well...  — Dave Bursky

[Embedded in Electronic Design]
Going Virtual
Virtual-machine (VM) technology has been around since well before Java or C# were even dreamed of. I used the UCSD Pascal P-system, which delivered portability. But its interpreted application performance was lacking compared to native code apps....  — William Wong

[Embedded in Electronic Design]
Fast Prototyping Without The Mess
Building prototype hardware from scratch can be time-consuming and error-prone. The MathWorks xPC TargetBox eliminates these problems with an off-the-shelf solution that is tightly integrated with xPC Target 2. The rugged xPC TargetBox is a...  — William Wong

[Embedded in Electronic Design]
Software Directory: Java Virtual Machines Solve The Puzzle
Java virtual machines (JVMs) are built from a variety of pieces. One is the Java language. Java bytecodes are the machine code for a JVM, and Java compilers are needed to translate from Java source to bytecodes. A garbage collector is a requirement,...  — William Wong

News Clips
Debugger Handles Multicore Configurable CPU Mentor Graphics' XRay Debugger now works with Tensilica's (www.tensilica.com) configurable Xtensa IV processing core. It is tightly coupled with Tensilica's...  — William Wong

[Celebrating 50 Years]
Flashback
Flashback > 10 Years Ago AUGUST 6, 1992 Because no one vendor can meet all design needs, users need to put together design environments that consist of multisourced tools. Whether these tools come from...  — Staff

Complementary SiGe BiCMOS Facilitates Precision High-Speed Analog
To extend its BiCOM biCMOS process into the next generation, Texas Instruments is tapping the benefits of complementary silicon-germanium (SiGe) bipolar transistors. TI has developed a third generation of fully isolated complementary SiGe biCMOS, or...  — Ashok Bindra

Tool Manages Virtual Memory Space
Virtual memory partitioning can impact the security and performance of embedded systems, so proper design is imperative. To help, Green Hills Software has added Integrate, a new tool, to its Integrity 4.0 real-time operating system (RTOS) for the...  — William Wong
