The Athlon 64 X2 is the first native dual-core desktop central processing unit (CPU) designed by Advanced Micro Devices (AMD). It was designed from scratch as native dual-core by using an already multi-CPU enabled Athlon 64, joining it with another functional core on one die, and connecting both via a shared dual-channel memory controller/north bridge and additional control logic.
Rijndael (standardised as AES) uses the characteristic 2 finite field with 256 elements, which can also be called the Galois field GF(2 8). It employs the following reducing polynomial for multiplication: x 8 + x 4 + x 3 + x + 1. For example, {53} • {CA} = {01} in Rijndael's field because
On December 19, 2000, Six Flags Magic Mountain announced that it would be adding three roller coasters for the 2001 season as part of a $30 million expansion: Déjà Vu, Goliath Jr. and the original X. This would bring the total to 15, beating the world coaster capital, Cedar Point. [2] X was a prototype 4th Dimension roller coaster by Arrow ...
The Tianhe-2 supercomputer uses 4096 Galaxy FT-1500 processors with 16 cores, OpenSPARC architecture based and 65 W TDP. They are made with 40 nm technology, processor cores work at 1.8 GHz. [ 10 ] Peak performance of FT-1500 is 115–144 GFLOPS; every core may execute up to 8 interleaving threads and supports 256-bit wide SIMD vector ...
In computing, octuple precision is a binary floating-point-based computer number format that occupies 32 bytes (256 bits) in computer memory.This 256-bit octuple precision is for applications requiring results in higher than quadruple precision.
For example, using a compass, straightedge, and a piece of paper on which we have the parabola y=x 2 together with the points (0,0) and (1,0), one can construct any complex number that has a solid construction. Likewise, a tool that can draw any ellipse with already constructed foci and major axis (think two pins and a piece of string) is just ...

00000000000 2 =000 16 is used to represent a signed zero (if F = 0) and subnormal numbers (if F ≠ 0); and; 11111111111 2 =7ff 16 is used to represent ∞ (if F = 0) and NaNs (if F ≠ 0), where F is the fractional part of the significand. All bit patterns are valid encoding. Except for the above exceptions, the entire double-precision number ...
