Power Instruction Set Architecture Version 2.06 The Power Architecture Advisory Council announces the public availability of Power ISA 2.06. This version is a major advance for the server and the embedded Power architecture. Major extensions include a new Vector-Scalar Floating-Point facility that supports vector and scalar floating-point operations, numerous new fixed-point, floating-point, and memory-management instructions, a new storage attribute, support for stronger storage access ordering, new storage control features, and many other enhancements. Extensions to the Embedded environment include an enhanced memory management architecture, logical partitioning and hypervisor support, embedded page table support, and multi-threading [Power.org]
Power Instruction Set Architecture Version 2.05 The Power Architecture Advisory Council has advanced another step in the Power ISA roadmap. Power ISA version 2.05 enhances the capabilities of the architecture with the addition of decimal floating point facilities, power management capabilities, new instructions supporting computation efficiency and memory management, new facilities for measuring resource utilization and partition migration, and other enhancements.

Whitepaper – What is New in the Server Environment of Power ISA v2.06? 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]
Whitepaper – Hypervisors Thrive with Power Architecture The use of multicore processors is on the rise, and hardware virtualization technology provides a complementary and game-changing approach to maximize the utility of that extra silicon horsepower. Power Architecture has included hardware virtualization support since 2001 in its server-based ISA. However, with the advent of Power Architecture ISA 2.06, hardware virtualization is now being promulgated into general purpose embedded processors. This paper discusses the hardware and software capabilities behind embedded virtualization for Power Architecture-based systems.[Power.org]
Whitepaper on Power Architecture Competitive Differentiation – Wireless Access The wireless access market segment is dominated today by the realities of long-term evolution (LTE). Many companies are strongly committed to LTE and believe that it offers simplified technology, better scalability, and ultimately a better user experience for next-generation mobile broadband. This whitepaper explores how Power Architecture supports the needs of the LTE market segment through (1) efficient and reliable support for heterogeneous systems integration, (2) scalability for system-level throughput as well as single-thread performance, (3) power savings and power management features, and (4) ease of programmability and a rich software ecosystem.[Power.org]

A usage scenario is provided. [Electronics Products]
Whitepaper on Stride and Prefetch feature in ISA 2.06 With the release of Power ISA v.2.06 many new features are added to the architecture to further improve the performance of the architecture. One such feature which is added in Power ISA v.2.06 to improve application performance is Stride N prefetch. Software prefetching is a promising techniques for addressing the processor-memory performance gap. Applications can benefit from data prefetch capabilities of Power Architecture super scalar processors.[IBM]
Embedded Power Architecture Platform Requirements (ePAPR) The Embedded Power Architecture Platform Requirements provides a complete boot program to client program interface definition, combined with minimum system requirements that facilitate the development of a wide variety of embedded systems based on CPUs that implement the Power Architecture as defined in the Power ISA. This specification is targeted towards the requirements of embedded systems. [Power.org]
Common Debug Interface API Specification Today almost every device software development tool on the market has its own method of communicating with target systems. Communication methods often conflict with each other, require individual setup, configuration and maintenance, or impose all kinds of unnecessary limitations. The primary purpose of this standard is to establish a standard protocol for defining and accessing new target services. The standard additionally specifies a standard language binding for clients to locate and access services and for target agents to deploy new services. [Power.org]
Common Debug Interface Target Debug Capabilities Specification The Target Debug Capabilities Specification defines what debug features, functionalities, and environment should be included in a target (processor, core, SoC) to support uni-core and multi-core design and to observe the system under test with minimal (or no) intrusion on its normal operation. This specification should be seen as an extension of the debugging features provided by the Power ISA. [Power.org]
Common Debug Interface White Paper The Power.org Common Debug Interface Technical Subcommittee has chartered a workgroup to define an API for the Power Architecture™ debug environment. The API workgroup has looked at existing debugging standards and concluded that something more scalable, flexible, and powerful is needed. The purpose of this paper is to document the vision for resolving the lack of a unified and scalable communication mechanism between the target and the host for the purpose of debug, performance analysis and other development activities. It gives a high-level view of the problem, the proposed communication framework, and examples of communication services. [Power.org]
