SGI Onyx is a series of visualization systems designed and manufactured by SGI, introduced in 1993 and offered in two models, deskside and rackmount, codenamed Eveready and Terminator respectively. The Onyx's basic system architecture is based on the SGI Challenge servers, but with graphics hardware.
Onyx2, codenamed Kego, is a family of visualization systems. It was developed and manufactured by SGI, and introduced in 1996 to succeed the Onyx.Onyx2 architecture is based on Origin 2000 server plus graphics hardware.
Copy a 32-bit, 64-bit or 128-bit memory operand to all elements of a XMM or YMM vector register. VINSERTF128: Replaces either the lower half or the upper half of a 256-bit YMM register with the value of a 128-bit source operand. The other half of the destination is unchanged. VEXTRACTF128
The TBM instructions are all encoded using the XOP prefix. They are all available in 32-bit and 64-bit forms, selected with the XOP.W bit (0=32bit, 1=64bit). (XOP.W is ignored outside 64-bit mode.) Like all instructions encoded with VEX/XOP prefixes, they are unavailable in Real Mode and Virtual-8086 mode.
The EVEX scheme is a 4-byte extension to the VEX scheme which supports the AVX-512 instruction set and allows addressing new 512-bit ZMM registers and new 64-bit operand mask registers. With Advanced Performance Extensions , the Extended EVEX prefix redefines the semantics of several payload bits.

VPCMOV works as bitwise variant of the blend instructions in SSE4. Like the AVX instruction VPBLENDVB, it is a four-operand instruction with three source operands and a destination. For each bit in the third operand (which acts as a selector), 1 selects the same bit in the first source, and 0 selects the same in the second source.
This technique packs two 16-bit instructions into one 32-bit word, which is then unpacked at the decode stage and executed as two instructions. [15] Minimal instruction set computers (MISC) are commonly a form of stack machine, where there are few separate instructions (8–32), so that multiple instructions can be fit into a single machine word.
