The x86 instruction set has several times been extended with SIMD (Single instruction, multiple data) instruction set extensions.These extensions, starting from the MMX instruction set extension introduced with Pentium MMX in 1997, typically define sets of wide registers and instructions that subdivide these registers into fixed-size lanes and perform a computation for each lane in parallel.
Below is the full 8086/8088 instruction set of Intel (81 instructions total). [2] These instructions are also available in 32-bit mode, in which they operate on 32-bit registers (eax, ebx, etc.) and values instead of their 16-bit (ax, bx, etc.) counterparts.
Precision control, rounding, and conversion instructions AMD claimed SSE5 would provide dramatic performance improvements, particularly in high-performance computing (HPC), multimedia , and computer security applications, including a 5x performance gain for AES encryption and a 30% performance gain for the discrete cosine transform (DCT) used ...
They are young, old, burly, thin, black and white. Among them are firefighters, lorry drivers, soldiers, security guards, a journalist and a DJ. These are the 50 men accused of raping Gisèle ...
Learn how muscle memory works, how long it takes to develop, and why it’s crucial for fitness. Plus, tips to train smarter and build strength and muscle faster.
Opioid overdose. With the opioid epidemic claiming roughly 80,000 lives each year in the U.S., advocates encourage everyone to carry and learn how to use naloxone (also known as Narcan), which can ...
A set of instructions that converted single- and double-precision floating-point numbers to 32-bit words were added. These complemented the existing conversion instructions by allowing the IEEE rounding mode to be specified by the instruction instead of the Floating Point Control and Status Register.
The point machine (in this case an electric motor) and associated mechanism used to operate this switch can be seen to the right in the picture. A point machine (also known as a point motor, switch machine or switch motor) is a device for operating railway turnouts especially at a distance.
