2eSST: Today's VME Performance Booster - article
VME deployment has grown increasingly since its adoption in the early 1980s, renewing and evolving as newer and better technologies are added to its architecture. During the past 25 years, VME has kept pace with innovation by increasing data transfer rates, adding fabric connectivity while maintaining backward compatibility at the pin level to preserve legacy functionality and investment. VME has reigned in critical embedded applications because it provides the required level of determination, low latency, and low processing overhead. Now 2eSST moves to the front lines, accelerating VMEbus performance. (Reprinted from VME and Critical Systems) Download the complete article

2eSST: Today's VME performance booster - application note
System designers need to understand the pros and cons of every VME bus standard available before implementing them in a new product. Although introduced in 2004, there has been little written about 2eSST, the highest performing VME bus standard. It can be used today in critical embedded systems for large performance gains without any significant change to system architecture. High end, critical embedded systems make use of multiple processors, distributed memory, and multiple I/O cards which requires large backplane bandwidth. Designers can choose to upgrade the VME bus performance with 2eSST or adopt one of the new serial based interconnect standards. Download the complete article

Overcoming the PCI Express Debugging Nightmare
Embedded computing systems using serial protocols are challenging to debug, especially serial fabrics such as PCI Express (PCIe). Embedded developers may have difficulty connecting the test instruments to the system, which could have a greater impact on system behavior than what they would expect. Hardward debugging now consists of two different disciplines, adding to the challenges. Leif discusses some of the perils of test equipment and suggests ways to debug PCIe protocol issues.

Testing PCI Express on AdvancedMC Modules
The Advanced Mezzanine Card (AdvancedMC) standard provides new challenges for system designers. Its form factor is optimized to fit easily in a range of carrier cards in AdvancedTCA and MicroTCA systems. The AMC.0 base specification and the subspecifications for PCI Express (AMC.1), Gigabit Ethernet (AMC.2), and Serial ATA (AMC.3) enable the designer to address a wide variety of applications and needs. However, this flexibility comes at the price of complexity. (Also available on ATCA Newsletter) Download the complete article

Getting the Most from XMCs
Extended Mezzanine Card (XMC) products are starting to appear, bringing high-speed fabric technology to the PMC form factor. Users have become familiar with debugging PCI bus and PCI-X bus, but new fabrics such as PCI Express on XMC modules call for new techniques. This article will explore the use of an XMC-based PCI Express analyzer for debugging link training, messaging, performance monitoring, protocol errors and driver issues.(Reprinted from MIL/COTS Digest) Download the complete article

Considerations in selecting a bus analyzer
Typically a bus analyzer is a single board unit; thus making it portable and ready-to-run. Bus Analyzers are available for many standardized form factors including VME, PCI, PCI-X, PMC and CompactPCI. When selecting a bus analyzer, engineers often consider several factors.

Remote debugging with networked bus analyzers
Remote debugging of VMEbus systems has in the past been unreliable and difficult. New developments such as the inclusion of a network interface within VME bus analyzer technology have made remote analysis far easier and more reliable. This makes deploying test instruments into remote and inaccessible systems more achievable. (reprinted from VMEbus Systems) Download the complete article
