Test-Driven Development: Designing high quality from the start
By Bruce Powel Douglass, PhD (Telelogic)
Summary:
Experience shows that if a system isn't well designed and implemented, then testing cannot improve its quality ex post facto.

Data-oriented architecture: A loosely coupled real-time SOA
By Rajive Joshi, PhD (Real-Time Innovations, Inc.)
Summary:
The scale and complexity of integration is growing at an increasingly fast pace as more devices and systems are integrated into our networked world. Accordingly, existing methodologies and training for system software design that worked wonders for small-scale systems begin to break down in light of operational limits, especially on large-scale distributed systems, which are often a mix of subsystems created by independent parties using different middleware technologies with misaligned interfaces. An overview of some fundamental challenges of integrating such subsystems using object-oriented thinking is presented.

CORBA for FPGAs: Tying together GPPS, DSPs, and FPGAs
By Joseph M Jacob (Objective Interface Systems) and Manuel Uhm (Xilinx)
Summary:
There are numerous advantages of using CORBA with FPGA-based systems. CORBA support for partial reconfigurability, in particular, speeds development of embedded systems and promotes code reuse across multiple generations of products, to increase portability of applications.

SysM-Based Systems Engineering Using a Model-Driven Development Approach
By Hans-Peter Hoffmann, Ph.D. (IBM)
Summary:
This paper describes a SysML-based process that systems engineers can use to capture requirements and specify architecture. The approach uses model execution as a means for requirements verification and validation.

IEEE-1588 Precision Time Protocol: Essential to next-generation test systems
By Paul Skoog (Symmetricom)
Summary:
Because IEEE-1588 can provide precise synchronization using packets, it’s a logical option for synchronizing test equipment deployed on a packet network.

Incremental innovation: How much more can be designed into CompactPCI?
By Bob Ehlers (Performance Technologies)
Summary:
Kaizen is the Japanese term that means continuous improvement and is taken from the words kai meaning continuous and zen meaning improvement. Some translate kai to mean change and zen to mean good, or for the better. In 1995, the PCI Industrial Computer Manufacturers Group (PICMG) introduced CompactPCI, or PICMG 2.x. At the time, it represent... (continues)
