Power ISA Documentation

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. [Power.org]

Power.org Public Specifications, White Papers, and Tools

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 Physical Connection for High-speed Serial Trace Specification
The CDI Physical Connection for High Speed Serial Trace Specification defines a high-speed serial protocol and connection method for the next generation of trace. It outlines the implementation and design criteria for creating a product and includes documentation that will aid in design. The serial protocol defined is scalable, occupies minimal printed circuit board space, and employs commonly used physical layers. [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]

Early Development Tools Matrix
The Power Architecture Early Development Tools Matrix is a listing of pre-silicon and systems development tools available for the Power Architecture platform. The matrix demonstrates the breadth and depth of development tools that are readily available for Power Architecture cores and SoCs. [Power.org]

Embedded Bus Architecture Report
The Power.org Bus Architectures Technical Subcommittee studied a number of buses in order to determine the hierarchy of buses that would become standardized for Power.org. The Embedded Bus Architecture Report describes the buses that are recommended, how they compare to one another, how they connect to one another, and what types of IP cores and models are available on each. [Power.org]

PLB4 Interoperability Specification
PLB4 offers many features, and this specification lists guidelines to follow as to what features must be implemented in new PLB4 core designs in order to ensure interoperability with PLB4 cores that are currently available. [Power.org]

PLB4 Architecture Specification
PLB4, of IBM's CoreConnect family of buses, was selected along with AHB as one of the Power.org mid-performance buses. PLB4 has advanced features such as bursting and pipelining, and offers a direct-attach point to the IBM 4xx family of embedded processors. [IBM]

PPC970MP Reference Design
Schematics for a server/workstation reference design based on the dual core 970MP processors from IBM. [Power.org]

Power Architecture Toolkits and Technical Specifications

Power Evaluation Kit (PEK)
The PEK enables designers to evaluate, build, and verify SoC designs. The first version of this kit is an SoC analysis framework which includes the IBM ChipBench™ System Level Design (ChipBench SLD) tool and a set of SystemC transaction-level architecture models. These models are designed to enable embedded software development and performance analysis for consumer applications based on Power Architecture™ technology. The tools can help designers quickly evaluate the effects of design trade-offs on performance, power, timing, and die size. [IBM developerWorks]

Cell processor technical specifications
Early details of Cell's technical specifications were disclosed in papers delivered at San Francisco's International Solid State Circuit Conference (ISSCC) in February, 2005. The documents just released (listed below) broaden the disclosures and put the details into the framework of the Cell Broadband Engine Architecture. [IBM developerWorks]

• The Cell Broadband Engine Architecture: Defines a processor structure directed toward distributed processing and multimedia applications. This structure contains a Power Architecture processor augmented with multiple high-performance single instruction, multiple data (SIMD) Synergistic Processor Units and a rich set of DMA commands for efficient communications among processing elements.
• The Synergistic Processor Unit Instruction Set Architecture (SPU ISA): Discloses the high-performance SIMD RISC processor designed to accelerate media and streaming applications for systems based upon the Cell Broadband Engine Architecture.
• Synergistic Processor Unit C\C++ Language Extensions, Application Binary Interface, and Assembly Language specifications: Aiding software developers in unleashing the full processing power of the SPUs.
