The other, known as Memtest86+, is a development fork of the original MemTest86. Their on-screen appearance and functionality were almost identical until MemTest86 4.3 and Memtest86+ 5.0. [1] Version 5.0 of MemTest86 added a mouse-driven graphical user interface (GUI) and UEFI support; the latter was added by Memtest86+ from version 6.0.
Key Locker common instructions. LOADIWKEY xmm1,xmm2: F3 0F 38 DC /r: Load internal wrapping key ("IWKey") from xmm1, xmm2 and XMM0. The two explicit operands (which must be register operands) specify a 256-bit encryption key. The implicit operand in XMM0 specifies a 128-bit integrity key. EAX contains flags controlling operation of instruction.
The 3DNow! instruction set extension was introduced in the AMD K6-2, mainly adding support for floating-point SIMD instructions using the MMX registers (two FP32 components in a 64-bit vector register). The instructions were mainly promoted by AMD, but were supported on some non-AMD CPUs as well. The processors supporting 3DNow! were:
Instruction set extensions that have been added to the x86 instruction set in order to support hardware virtualization.These extensions provide instructions for entering and leaving a virtualized execution context and for loading virtual-machine control structures (VMCSs), which hold the state of the guest and host, along with fields which control processor behavior within the virtual machine.
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.
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.

In the x86 assembly language, the TEST instruction performs a bitwise AND on two operands. The flags SF, ZF, PF are modified while the result of the AND is discarded. The OF and CF flags are set to 0, while AF flag is undefined. There are 9 different opcodes for the TEST instruction depending on the type and size of the operands. It can compare ...
