In 1990, IBM released the RISC System/6000, later shortened to IBM RS/6000, which was the progenitor of the high-performance, low-energy-consumption line of IBM Power Systems. It used multi-chip architecture, allowing for a family of workstations and servers that brought unprecedented power to the desks of scientists and engineers, among others.

The RISC System/6000 is a family of RISC -based (Reduced Instruction Set Computer-based) Unix servers, workstations and supercomputers made by IBM in the 1990s. The RS/6000 family replaced the IBM RT PC computer platform in February 1990 and is the first computer line to see the use of IBM's POWER and PowerPC based microprocessors.

In electronics and computer science, a reduced instruction set computer (RISC) is a computer architecture designed to simplify the individual instructions given to the computer to accomplish tasks.

Introduction This paper describes the machine organization of the IBM RISC System/6000* (RS/6000) processor. Companion papers in this issue describe the instruction- * RlSC System/6000 is a trademark of International Business Machmes Corporation.

IBM rolls out in February the RISC System/6000 Model 3CT and Model 39H; IBM Xstation 160, the first IBM product to incorporate a PowerPC 603 microprocessor; and a new, RS/6000-based processor for the IBM SP2 offering higher number crunching performance than its …

This paper traces the evolution of IBM RISC architecture from its origins in the 1970s at the IBM Thomas J. Watson Research Center to the present-day IBM RISC System/6000* computer. The acronym RISC, for Reduced Instruction-Set Computer, is used in this paper to describe the 801 and subsequent architectures.

A highly concurrent superscalar second-generation family of RISC workstations and servers is described. The RISC System/6000* family is based on the new IBM POWER (Performance Optimization With Enhanced RISC) architecture; the hardware implementation takes advantage of this powerful RISC architecture and employs sophisticated design techniques ...

The IBM RISC System/6000 realizes the idea of a superscalar microprocessor. The architecture of this processor has its instruction set specifically designed for a superscalar machine containing three independent units—branch, fixed-point, and floating-point.

Jan 1, 2000 · This paper traces the evolution of IBM RISC architecture from its origins in the 1970s at the IBM Thomas J. Watson Research Center to the present-day IBM RISC System/6000* computer.

This paper describes the hardware architecture of the IBIVI RISC System/6000* processor, which combines basic RISC principles with a partitioning of registers by function into multiple ALUs.
