Power ISA is a RISC load/store architecture. It has multiple sets of registers: 32 × 32-bit or 64-bit general-purpose registers (GPRs) for integer operations. 64 × 128-bit vector scalar registers (VSRs) for vector operations and floating-point operations. 32 × 64-bit floating-point registers (FPRs) as part of the VSRs for floating-point ...
Microwatt is a tiny 64-bit bi-endian scalar integer processor core, implementing a subset of the Power ISA 3.0 instruction set. It has 32× 64-bit general purpose registers and 32x 64-bit floating-point registers. It uses Wishbone for the memory interface. [4]
IBM POWER is a reduced instruction set computer (RISC) instruction set architecture (ISA) developed by IBM. The name is an acronym for Performance Optimization With Enhanced RISC. [1] The ISA is used as base for high end microprocessors from IBM during the 1990s and were used in many of IBM's servers, minicomputers, workstations, and ...
Libre-SOC is a libre soft processor core originally written by Luke Leighton and other contributors, announced at the OpenPOWER Summit NA 2020. [2] It adheres to the Power ISA 3.0 instruction set and can be run on field-programmable gate array boards, currently booting MicroPython and other bare-metal applications.
OpenPOWER – Power ISA, an open-source hardware instruction set architecture initiated by IBM; OpenSPARC – Sun's, later Oracle's high-performance processor; Parallax Propeller – a multi-core microcontroller with eight 32-bit RISC cores; Parallella – single-board computer with a manycore coprocessor and field-programmable gate array (FPGA)
The e5500 core is the first 64-bit Power ISA core designed solely by Freescale and was introduced at Freescale Technology Forum in June 2010. Simulated models were available in July 2010, hard samples in late 2010 and full scale manufacturing the second half of 2011.
POWER7+, 64-bit octo core, 4 way SMT/core, 3.0–5.0 GHz, follows the Power ISA 2.06. Introduced in 2012. POWER8, 64-bit, hex or twelve core, 8 way SMT/core, 5.0 GHz, follows the Power ISA 2.07. Introduced in 2014. POWER9, 64-bit, PowerNV 24 cores of 4 way SMT/core, PowerVM 12 cores of 8 way SMT/core, follows the Power ISA 3.0. Introduced in ...
Dual 375 MHz IBM POWER3-II processors on the CPU module of a RS/6000 44P 270. The POWER3 is a microprocessor, designed and exclusively manufactured by IBM, that implemented the 64-bit version of the PowerPC instruction set architecture (ISA), including all of the optional instructions of the ISA (at the time) such as instructions present in the POWER2 version of the POWER ISA but not in the ...
