July 10, 2008 Make Or Buy: Module Mania
Make it low-power. Buying off-the-shelf parts to meet these criteria is still a challenge, but the latest crop of modules makes the job easier. Modules let designers develop custom configurations with minimum moving the design of the critical aspects of the system to the module vendors. This includes the processor and memory subsystem and usually most, if not all, of the peripheral interface. A carrier board typically contains connectors and...

July 10, 2008 USB Spans 8- To 32-Bit MCUs
Microchip’s latest microcontrollers, from its 8-bit PICs to 32-bit MIPS-based chips, now sport USB. At the low end is the small-footprint PIC18F1XK50 family. The 16-bit PIC24F family now adds USB OTG (On the Go) support, as does the low-cost, 40-MHz, 32-bit PIC32MX420. Other PIC32 systems run at speeds up to 80 MHz. Pricing starts at $1.32, $3.47, and $3.25, respectively. MICROCHIP ...

July 10, 2008 Distributed Computing Augments Math Tool
The Parallel Computing Toolbox and matching Distributed Computing Server augment the MathWorks’ Matlab 2008a with parallel computing support that will be a boon to number-crunching developers. New features include parallel for (parfor) definitions as well as distributed arrays (darray) that allow data to be distributed across many servers. Users also can transition from serial Matlab programs to parallel Matlab programs without significant...

June 12, 2008 Shining A Light On Bugs
Turn on the lights and the cockroaches run away. This often seems to be the way to deal with programming bugs as well. Bring out the debugger or trace tools, and the problem goes away or remains difficult to locate. While application bugs don’t really react like real bugs, changing the state of an application’s environment does affect how buggy code responds. This is one reason why tools that impose no overhead on an application are...

June 12, 2008 Smaller Stackable USB
New 1/4- and 1/2-size PC/104 boards allow StackableUSB to deliver more compact solutions. A single SAMTEC connector links a motherboard like the Micro/ Sys Pentium III-based SBC1685 with up to eight stacked USB devices. The smaller form factors could allow multiple expansion boards to fit where single PC/104 expansion boards would reside today. This approach allows support for a carrier board that handles multiple expansion modules. ...

June 12, 2008 Multicore, Multithreaded Goes Embedded
MIPS Technologies combines multithreaded and multicore support into its latest embedded SMP platform. As with most multithreaded designs, the MIPS32 1004K’s multithreaded support provides an incremental performance boost that is less than adding another full core. Still, multithreaded support can take advantage of a core’s idle time that would otherwise waste power— a critical item in most embedded designs. Each core can include one or two...

May 8, 2008 Will Virtualization Save The Day?
Will virtualization save multicore? Will it be the answer to a really secure system? It might. Designed to run on a single core, virtual- machine hypervisors give developers multiple virtual cores. Developers don’t need to care about whether there are enough physical cores available from an application standpoint. Of course, with more cores, you get more run time for virtual cores. But this doesn’t change how the applications are written or how they ...

May 8, 2008 Virtualization Moves Onto Custom Microcontroller
VIRTUALIZATION MOVES ONTO CUSTOM MICROCONTROLLER Developers using Atmel’s line of microcontrollers based on its ARM-based CAP architecture (see “Chip Twists ARM With Custom Logic” at www.electronicdesign. com, ED Online 15982) can now take advantage of Trango’s Hypervisor virtualization software. CAP’s FPGA-style logic is locked down at the factory before the chips ship, but Hypervisor works on these as well ...
