The EVEX prefix (enhanced vector extension) and corresponding coding scheme is an extension to the 32-bit x86 (IA-32) and 64-bit x86-64 (AMD64) instruction set architecture.
An instruction reference is available [5] − the instructions/opcodes unique to KNC are the ones with VEX and MVEX prefixes (except for the KMOV, KNOT and KORTEST instructions − these are kept with the same opcodes and function in AVX-512, but with an added "W" appended to their instruction names).
Branch to target if value is a non-null object reference (alias for brtrue). Base instruction 0x2D brinst.s <int8 (target)> Branch to target if value is a non-null object reference, short form (alias for brtrue.s). Base instruction 0x39 brnull <int32 (target)> Branch to target if value is null (alias for brfalse). Base instruction 0x2C
The VEX coding scheme uses a code prefix consisting of two or three bytes, which may be added to existing or new instruction codes. [2]The VEX prefix replaces the 0x66, 0xF2 and 0xF3 opcode prefixes, the REX prefix, and the 0x0F, 0x0F 0x2E or 0x0F 0x3E opcode prefixes.
SSSE3 was first introduced with Intel processors based on the Core microarchitecture on June 26, 2006 with the "Woodcrest" Xeons.. SSSE3 has been referred to by the codenames Tejas New Instructions (TNI) or Merom New Instructions (MNI) for the first processor designs intended to support it.
Fixed-block architecture (FBA) is an IBM term for the hard disk drive (HDD) layout in which each addressable block (more commonly, sector) on the disk has the same size, utilizing 4 byte block numbers and a new set of command codes. [1]

In computing, the reset vector is the default location a central processing unit will go to find the first instruction it will execute after a reset.The reset vector is a pointer or address, where the CPU should always begin as soon as it is able to execute instructions.
