Additions and Enhancements to the Power ISA v2.06 extend the advantages of the Power Architecture ranging from performance, flexibility, and RAS to energy efficiency. Vector-Scalar Extension (VSX) – a major addition in v2.06 - extends the edge Power ISA has in HPC and computation-intensive workloads. Power ISA v2.06 continues to provide enhancements to the server space such as memory management, processor version compatibility features, cache management, etc and also introduces a number of capabilities for the embedded space such as embedded hypervisor, energy management, multi-core and multi-threading. This white paper highlights the major changes and their merits. The focus is on the Server ISA. [Power.org]
