This trend was motivated by the need to provide dedicated interconnection fabric — much in the same way everyone with a bit-mapped display, and it was made as a building’s telephone services are accessed by a possible by the widespread availability of collection of handset devices. The stateless desktop design high-performance workstations. However, the desktop provides a useful mobility model in which users can computing model is not without its problems, many of transparently resume their work on any desktop console. which were raised by the original UNIX designers[14]: This paper examines the fundamental premise in this “Because each workstation has private data, each system design that modern, off-the-shelf interconnection must be administered separately; maintenance is technology can support the quality-of-service required by difficult to centralize.

  • Ultrasparctm II Microprocessor
    UltraSPARCTM II Microprocessor High-Performance, Highly-Scalable, Multiprocess- The UltraSPARC II processor microarchitecture is designed ing, 64-bit SPARC™ V9 RISC Microprocessor to provide up to 4-way glueless multiprocessing support and supports up to 64-way systems. The processor sup- ports multiple L2 cache speeds and sizes to enable high- performance multiprocessing systems. Balanced overall system performance requires optimal performance along three critical levels: memory band- width, media processing, and raw compute performance. A highly-scalable, high-performance system interconnect ensures a bottleneck-free computing environment result- ing in high memory bandwidth. VIS™ (Visual Instruction Set) multimedia extensions boost the performance of graphics-intensive multimedia applications, and thus reduce overall system costs by eliminating the need for a special-purpose media processor. And the UltraSPARC II delivers superior raw compute performance by using the Placeholder for illustration or photo most innovative RISC microprocessor architecture and state-of-the-art process technology. The UltraSPARC II processor not only helps the system designer by implementing industry-standard testing and instrumentation interfaces, it also uses Error Checking & Correction (ECC) and parity to increase system reliability. With high performance, high scalability, and high reliabil- ity, the UltraSPARC II is the processor of choice for today’s workstations and servers. FEATURES • Full 64-bit implementation of SPARC V9 architecture • 100% binary compatibility with previous versions of SPARC systems The state-of-the-art UltraSPARC™ II processor is the second • Built-in MP support (glueless 4-way and up to 64-way) generation in the UltraSPARC s-series microprocessor fam- • High-performance UPA system interconnect ily.

A given ISA may be implemented with different microarchitectures.[1] Implementations might vary due to different goals of a given design or due to shifts in technology.[2] Computer architecture is the combination of microarchitecture and instruction set design. Relation to instruction set architecture The ISA is roughly the same as the programming model of a processor as seen by an assembly language programmer or compiler writer. The ISA includes the execution model, processor registers, address and data formats among other things. The Intel Core microarchitecture microarchitecture includes the constituent parts of the processor and how these interconnect and interoperate to implement the ISA. The microarchitecture of a machine is usually represented as (more or less detailed) diagrams that describe the interconnections of the various microarchitectural elements of the machine, which may be everything from single gates and registers, to complete arithmetic logic units (ALU)s and even larger elements.
