Ppc64
ppc64 is an identifier commonly used within the Linux, GNU Compiler Collection (GCC) and LLVM free software communities to refer to the target architecture for applications optimized for 64-bit big-endian PowerPC and Power ISA processors. ppc64le is a pure little-endian mode that has been introduced with the POWER8 as the prime target for technologies provided by the OpenPOWER Foundation, aiming at enabling porting of the x86 Linux-based software with minimal effort. Details These two identifiers are frequently used when compiling source code to identify the target architecture. 64-bit Power and PowerPC processors are the following: * PowerPC 620 * RS64 – Apache, RS64-II Northstar, RS64-III Pulsar/IStar, and RS64-IV SStar * POWER3 and POWER3-II * POWER4 and POWER4+ * PowerPC 970, 970FX, 970MP and 970GX * POWER5 and POWER5+ * PPE in Cell BE, PowerXCell 8i and Xenon. * PWRficient * POWER6 and POWER6+ * POWER7 and POWER7+ * A2, A2I (used in the Blue Gene/Q) an ...

PowerPC
PowerPC (with the backronym Performance Optimization With Enhanced RISC – Performance Computing, sometimes abbreviated as PPC) is a reduced instruction set computer (RISC) instruction set architecture (ISA) created by the 1991 Apple Inc., Apple–IBM–Motorola alliance, known as AIM alliance, AIM. PowerPC, as an evolving instruction set, has been named Power ISA since 2006, while the old name lives on as a trademark for some implementations of Power Architecture–based processors. Originally intended for personal computers, the architecture is well known for being used by Apple's desktop and laptop lines from 1994 until 2006, and in several videogame consoles including Microsoft's Xbox 360, Sony's PlayStation 3, and Nintendo's GameCube, Wii, and Wii U. PowerPC was also used for the Curiosity (rover), Curiosity and Perseverance (rover), Perseverance rovers on Mars and a variety of satellites. It has since become a niche architecture for personal computers, particularly with A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OpenPower Microwatt
Microwatt is an open source soft processor core originally written in VHDL by Anton Blanchard at IBM, announced at the OpenPOWER Summit NA 2019 and published on GitHub in August 2019. It adheres to the Power ISA 3.0 instruction set and can be run on FPGA boards, booting Linux, MicroPython and Zephyr.

POWER9
POWER9 is a family of superscalar, multithreading, multi-core microprocessors produced by IBM, based on the Power ISA. It was announced in August 2016. The POWER9-based processors are being manufactured using a 14 nm FinFET process, in 12- and 24-core versions, for scale out and scale up applications, and possibly other variations, since the POWER9 architecture is open for licensing and modification by the OpenPOWER Foundation members. Summit, the ninth fastest supercomputer in the world (based on the Top500 list as of June 2024), is based on POWER9, while also using Nvidia Tesla GPUs as accelerators. Design Core The POWER9 core comes in two variants, a four-way multithreaded one called ''SMT4'' and an eight-way one called ''SMT8''. The SMT4- and SMT8-cores are similar, in that they consist of a number of so-called ''slices'' fed by common schedulers. A slice is a rudimentary 64-bit single-threaded processing core with load store unit (LSU), integer unit (ALU) and a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power ISA
Power ISA is a reduced instruction set computer (RISC) instruction set architecture (ISA) currently developed by the OpenPOWER Foundation, led by IBM. It was originally developed by IBM and the now-defunct Power.org industry group. Power ISA is an evolution of the PowerPC ISA, created by the mergers of the core PowerPC ISA and the optional Book E for embedded applications. The merger of these two components in 2006 was led by Power.org founders IBM and Freescale Semiconductor. Prior to version 3.0, the ISA is divided into several categories. Processors implement a set of these categories as required for their task. Different classes of processors are required to implement certain categories, for example a server-class processor includes the categories: ''Base'', ''Server'', ''Floating-Point'', ''64-Bit'', etc. All processors implement the Base category. Power ISA is a RISC load/store architecture. It has multiple sets of registers: * ''32'' × 32-bit or 64-bit general- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OpenPOWER Foundation
The OpenPOWER Foundation is a collaboration around Power ISA-based products initiated by IBM and announced as the "OpenPOWER Consortium" on August 6, 2013. IBM's focus is to open up technology surrounding their Power Architecture offerings, such as processor specifications, firmware, and software with a liberal license, and will be using a collaborative development model with their partners. The goal is to enable the server vendor ecosystem to build its own customized server, networking, and storage hardware for future data centers and cloud computing. The governing body around the Power ISA instruction set architecture, instruction set is now the OpenPOWER Foundation: IBM allows its patents to be royalty-free for Compliant implementations. Processors based on IBM's Intellectual property, IP can now be fabricated on any foundry and mixed with other hardware products of the integrator's choice. On August 20, 2019, IBM announced that the OpenPOWER Foundation would become part of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cell (microprocessor)
The Cell Broadband Engine (Cell/B.E.) is a 64-bit multi-core processor and microarchitecture developed by Sony, Toshiba, and IBM—an alliance known as "STI". It combines a general-purpose PowerPC core, called the Power Processing Element (PPE), with multiple specialized coprocessors, known as Synergistic Processing Elements (SPEs), which accelerate tasks such as multimedia and vector processing. The architecture was developed over a four-year period beginning in March 2001, with Sony reporting a development budget of approximately . Its first major commercial application was in Sony's PlayStation 3 home video game console, released in 2006. In 2008, a modified version of the Cell processor powered IBM's Roadrunner, the first supercomputer to sustain one petaFLOPS. Other applications include high-performance computing systems from Mercury Computer Systems and specialized arcade system boards. Cell emphasizes memory coherence, power efficiency, and peak computational thro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Blue Gene/Q
Blue Gene was an IBM project aimed at designing supercomputers that can reach operating speeds in the petaFLOPS (PFLOPS) range, with relatively low power consumption. The project created three generations of supercomputers, Blue Gene/L, Blue Gene/P, and Blue Gene/Q. During their deployment, Blue Gene systems often led the TOP500 and Green500 rankings of the most powerful and most power-efficient supercomputers, respectively. Blue Gene systems have also consistently scored top positions in the Graph500 list. The project was awarded the 2009 National Medal of Technology and Innovation. After Blue Gene/Q, IBM focused its supercomputer efforts on the OpenPower platform, using accelerators such as FPGAs and GPUs to address the diminishing returns of Moore's law. History A video presentation of the history and technology of the Blue Gene project was given at the Supercomputing 2020 conference.
