SPARC T4
The SPARC T4 is a SPARC multicore microprocessor introduced in 2011 by Oracle Corporation. The processor is designed to offer high multithreaded performance (8 threads per core, with 8 cores per chip), as well as high single threaded performance from the same chip. The chip is the 4th generation processor in the T-Series family. Sun Microsystems brought the first T-Series processor (UltraSPARC T1) to market in 2005. The chip is the first Sun/Oracle SPARC chip to use dynamic threading and out-of-order execution. It incorporates one floating point unit and one dedicated cryptographic unit per core. The cores use the 64-bit SPARC Version 9 architecture running at frequencies between 2.85 GHz and 3.0 GHz, and are built in a 40 nm process with a die size of . History and design An eight core, eight thread per core chip built in a 40 nm process and running at 2.5 GHz was described in Sun Microsystems' processor roadmap of 2009. It was codenamed "Yosemite Fal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oracle SPARC T4 Chip 028
An oracle is a person or wikt:agency, agency considered to provide wise and insightful counsel or prophecy, prophetic predictions, most notably including precognition of the future, inspired by Deity, deities. As such, it is a form of divination. Description The word ''oracle'' comes from the Latin verb ''ōrāre'', "to speak" and properly refers to the priest or priestess uttering the prediction. In extended use, ''oracle'' may also refer to the ''site of the oracle'', and to the oracular utterances themselves, called ''khrēsmē'' 'tresme' (χρησμοί) in Greek. Oracles were thought to be portals through which the gods spoke directly to people. In this sense, they were different from seers (''manteis'', μάντεις) who interpreted signs sent by the gods through bird signs, animal entrails, and other various methods.Flower, Michael Attyah.

SPARC Microprocessors
SPARC (Scalable Processor Architecture) is a reduced instruction set computer (RISC) instruction set architecture originally developed by Sun Microsystems. Its design was strongly influenced by the experimental Berkeley RISC system developed in the early 1980s. First developed in 1986 and released in 1987, SPARC was one of the most successful early commercial RISC systems, and its success led to the introduction of similar RISC designs from many vendors through the 1980s and 1990s. The first implementation of the original 32-bit architecture (SPARC V7) was used in Sun's Sun-4 computer workstation and server systems, replacing their earlier Sun-3 systems based on the Motorola 68000 series of processors. SPARC V8 added a number of improvements that were part of the SuperSPARC series of processors released in 1992. SPARC V9, released in 1993, introduced a 64-bit architecture and was first released in Sun's UltraSPARC processors in 1995. Later, SPARC processors were used in sym ...

Branch Predictor
In computer architecture, a branch predictor is a digital circuit that tries to guess which way a branch (e.g., an if–then–else structure) will go before this is known definitively. The purpose of the branch predictor is to improve the flow in the instruction pipeline. Branch predictors play a critical role in achieving high performance in many modern pipelined microprocessor architectures such as x86. Two-way branching is usually implemented with a conditional jump instruction. A conditional jump can either be "taken" and jump to a different place in program memory, or it can be "not taken" and continue execution immediately after the conditional jump. It is not known for certain whether a conditional jump will be taken or not taken until the condition has been calculated and the conditional jump has passed the execution stage in the instruction pipeline (see fig. 1). Without branch prediction, the processor would have to wait until the conditional jump instruction has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oracle SPARC T-series Servers
The SPARC T-series family of RISC processors and server computers, based on the SPARC V9 architecture, was originally developed by Sun Microsystems, and later by Oracle Corporation after its acquisition of Sun. Its distinguishing feature from earlier SPARC iterations is the introduction of chip multithreading (CMT) technology, a multithreading, multicore design intended to drive greater processor utilization at lower power consumption. The first generation T-series processor, the UltraSPARC T1, and servers based on it, were announced in December 2005. As later generations were introduced, the term "T series" was used to refer to the entire family of processors. Pre-Oracle era Sun Microsystems' Sun Fire and SPARC Enterprise product lines were based on early generations of CMT technology. The UltraSPARC T1 based Sun Fire T2000 and T1000 servers were launched in December 2005 and early 2006, respectively. They were later rebranded to match the name of the UltraSPARC T2 and T2 Plu ...

L3 Cache
A CPU cache is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. A cache is a smaller, faster memory, located closer to a processor core, which stores copies of the data from frequently used main memory locations. Most CPUs have a hierarchy of multiple cache levels (L1, L2, often L3, and rarely even L4), with different instruction-specific and data-specific caches at level 1. The cache memory is typically implemented with static random-access memory (SRAM), in modern CPUs by far the largest part of them by chip area, but SRAM is not always used for all levels (of I- or D-cache), or even any level, sometimes some latter or all levels are implemented with eDRAM. Other types of caches exist (that are not counted towards the "cache size" of the most important caches mentioned above), such as the translation lookaside buffer (TLB) which is part of the memory management unit (MMU) whic ...

Floating Point
In computing, floating-point arithmetic (FP) is arithmetic that represents real numbers approximately, using an integer with a fixed precision, called the significand, scaled by an integer exponent of a fixed base. For example, 12.345 can be represented as a base-ten floating-point number: 12.345 = \underbrace_\text \times \underbrace_\text\!\!\!\!\!\!^ In practice, most floating-point systems use base two, though base ten (decimal floating point) is also common. The term ''floating point'' refers to the fact that the number's radix point can "float" anywhere to the left, right, or between the significant digits of the number. This position is indicated by the exponent, so floating point can be considered a form of scientific notation. A floating-point system can be used to represent, with a fixed number of digits, numbers of very different orders of magnitude — such as the number of meters between galaxies or between protons in an atom. For this reason, floating-poin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Instruction Pipeline
In computer engineering, instruction pipelining or ILP is a technique for implementing instruction-level parallelism within a single processor. Pipelining attempts to keep every part of the processor busy with some instruction by dividing incoming instructions into a series of sequential steps (the eponymous "pipeline") performed by different processor units with different parts of instructions processed in parallel. Concept and motivation In a pipelined computer, instructions flow through the central processing unit (CPU) in stages. For example, it might have one stage for each step of the von Neumann cycle: Fetch the instruction, fetch the operands, do the instruction, write the results. A pipelined computer usually has "pipeline registers" after each stage. These store information from the instruction and calculations so that the logic gates of the next stage can do the next step. This arrangement lets the CPU complete an instruction on each clock cycle. It is common for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
