On Power.org, the latest revision of the Power Instruction Set Architecture has been published.
In this latest update, there's a page and a half summary of the architectural changes being made. Teams are already updating Linux to take advantage of many of the new features across the various open-source communities.
The Power Architecture Advisory Council announces the public availability of Power ISA 2.07. This version is a major advance for the server and the embedded Power architecture. Major extensions include enhanced logical partitioning support with multiple logical partitions running concurrently on a server environment processor, the new Transactional Memory facility for data access synchronization, an expanded Vector facility that supports a broad range of business analytics, e-commerce, and infrastructure applications, expanded performance monitoring facilities for server and embedded systems, new storage control features for server and embedded systems, accelerated exception handling for Linux and AIX operating systems, and many other enhancements.
