Curing the longevity of supply blues - Blog

December 21, 2015
POWER ARCHITECTURE TODAY Blog: Longevity of supply is a concern that can keep embedded military program managers up at night for a long, long time. That’s because the time scale for deployed military systems is impressively lengthy. It’s not unusual for RFPs received today to require single board computers (SBC) that need to be supplied in production volumes into 2025-2030. That support period actually starts at the back-end of production, after an SBC has already been designed in and deployed. The time that it takes to get a selected SBC designed, and the software application written, for a new program can be as long as three to four years.

AltiVec is back - Blog

POWER ARCHITECTURE TODAY Blog: Freescale’s new T-series processor has brought back the AltiVec floating point SIMD instruction set, the heart of many defense and aerospace digital signal processing (DSP) applications for the last two decades. AltiVec, a mainstay of commercial-off-the-shelf (COTS) DSP boards for years, went missing in action for one series of previous devices. A disappearing act that led embedded system users to look for an alternative solution.

Dual-node SBCs: A hardware-based approach to red/black architectures - Story

June 10, 2015
As the need for data security increases, the need to support both encrypted data and less sensitive data within the same system is also on the rise. One approach for providing so-called red/black separation of sensitive and encrypted data in embedded computer systems is the use of partitioning operating systems such as MILS (Multiple Independent Levels of Security/Safety). For some users, though, a software-based partition solution is unappealing, because of concerns about robustness, design risks, or the associated costs of commercial operating systems, which have to undergo a rigorous National Security Agency (NSA) certification process.
