How to decide which form factor to use for a radar or sonar application? Consider the application's topology: Interconnect topologies that comprise many high-speed connections are well suited to VPX, while applications with more “well-behaved” communications are usually a good candidate for less complex technologies like CompactPCI.[Continue reading →]

David will discuss the characteristics of CompactPCI that make it suitable for mil and aero applications and use real-world examples to help readers recognize whether the CompactPCI form factor fits their applications. He will explore considerations for implementation of systems based on these architectures.Limitations of 3U VME in terms of bus width, bandwidth, and rear I/O pins make it impossible to use for many applications. Instead, designers choose 3U CompactPCI for these applications, as it supports a much higher bandwidth with plenty of rear I/O. Similarly, for high-performance applicationsthat require multiple CPUs processing data across a single back-plane, 6U CompactPCI’s derivative PICMG 2.16 is a logical choice, as it is more reliable and supports more rear I/O thanVITA 31 or VITA 41.

CompactPCI‚Äôs roots in PCI also make it more desirable than VME for many design groups. For example, new software designers already know and understand the development challenges for PCI applica-tions, while developing VME applications provides some unique challenges. Millions of software applications are CompactPCI compatible. These "comfort zone" factors that made CompactPCI quite success-ful in nondefense embedded applications are now helping to keep it as a prevalent architecture in defense applications.[Continue reading →]
