UltraSPARC II
The UltraSPARC II, code-named "Blackbird", is a microprocessor implementation of the SPARC, SPARC V9 instruction set architecture (ISA) developed by Sun Microsystems. Marc Tremblay was the chief architect. Introduced in 1997, it was further development of the UltraSPARC operating at higher clock rate, clock frequencies of 250 MHz, eventually reaching 650 MHz. The Die (integrated circuit), die contained 5.4 million transistors and had an area of 149 mm. It was Semiconductor device fabrication, fabricated by Texas Instruments in their 0.35 μm process, dissipated 25 W at 205 MHz, and used a 2.5 V power supply. L2 cache capacity was 1 to 4 MB. In 1999, the UltraSPARC II was ported to a 0.25 μm process. This version was code-named "Sapphire-Black". It operated at 360 to 480 MHz, possessed a die area of 126 mm, dissipated 21 W at 400 MHz and the power supply voltage was reduced to 1.9 V. Supported L2 cache capacity was increased to 1 to 8 ...

Sun Microsystems
Sun Microsystems, Inc., often known as Sun for short, was an American technology company that existed from 1982 to 2010 which developed and sold computers, computer components, software, and information technology services. Sun contributed significantly to the evolution of several key computing technologies, among them Unix, Reduced instruction set computer, RISC processors, thin client computing, and virtualization, virtualized computing. At its height, the Sun headquarters were in Santa Clara, California (part of Silicon Valley), on the former west campus of the Agnews Developmental Center. Sun products included computer servers and workstations built on its own Reduced instruction set computer, RISC-based SPARC processor architecture, as well as on x86-based AMD Opteron and Intel Xeon processors. Sun also developed its own computer storage, storage systems and a suite of software products, including the Unix-based SunOS and later Solaris operating system, Solaris operating s ...

Sun UltraSPARC IIe Back
The Sun is the star at the centre of the Solar System. It is a massive, nearly perfect sphere of hot Plasma (physics), plasma, heated to incandescence by nuclear fusion reactions in its core, radiating the energy from its surface mainly as visible light and infrared radiation with 10% at ultraviolet energies. It is by far the most important source of energy for life on Earth. The Sun has been an The Sun in culture, object of veneration in many cultures. It has been a central subject for astronomical research since Ancient history, antiquity. The Sun orbits the Galactic Center at a distance of 24,000 to 28,000 light-years. Its distance from Earth defines the astronomical unit, which is about or about 8 light-minutes. Solar radius, Its diameter is about (), 109 times that of Earth. solar mass, The Sun's mass is about 330,000 times that of Earth, making up about 99.86% of the total mass of the Solar System. The mass of outer layer of the Sun's atmosphere, its ''photosphere'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Superscalar Microprocessors
A superscalar processor (or multiple-issue processor) is a CPU that implements a form of parallelism called instruction-level parallelism within a single processor. In contrast to a scalar processor, which can execute at most one single instruction per clock cycle, a superscalar processor can execute or start executing more than one instruction during a clock cycle by simultaneously dispatching multiple instructions to different execution units on the processor. It therefore allows more throughput (the number of instructions that can be executed in a unit of time which can even be less than 1) than would otherwise be possible at a given clock rate. Each execution unit is not a separate processor (or a core if the processor is a multi-core processor), but an execution resource within a single CPU such as an arithmetic logic unit. While a superscalar CPU is typically also pipelined, superscalar and pipelining execution are considered different performance enhancement techniques ...
