BOARD STANDARDS SEEK THE HOLYGRAIL

摘要

Restricted budgets and shortened schedules have forced design teams to eschew propri-etary designs and adopt open standards for low- to medium-quantity, high-performance embedded projects, such as medical instru-mentation, military' systems, communications installations, and process automation. Their challenge is to select a standard that can de-liver the performance, form factor and costrnnecessary for the current project and offer ample expansion for expected updates to data rates and processing requirements. Today's board-level standards include names such as VMEbus, PCI, CompactPCI, PC/104, and AdvancedTCA (Advanced TelecomrnComputing Architecture), plus a variety or stand-alone modules and daughter-cards.
