BUPERS is led by the Chief of Naval Personnel (CHNAVPERS), who serves in an additional duty capacity as the Deputy Chief of Naval Operations for Personnel, Manpower, and Training (DCNO N1). As of 2024, the Bureau of Naval Personnel serves as an echelon II parent command to Navy Personnel Command (NAVPERSCOM).
The United States Navy Reserve (USNR), known as the United States Naval Reserve from 1915 to 2004, [1] is the Reserve Component (RC) of the United States Navy.Members of the Navy Reserve, called reservists, are categorized as being in either the Selected Reserve (SELRES), the Training and Administration of the Reserve (TAR), the Individual Ready Reserve (IRR), or the Retired Reserve.
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.
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 shift in focus from navigation to personnel management, brought a change in name during World War II. In 1942, the Bureau of Navigation was redesignated the Bureau of Naval Personnel (BuPers), under which name it still exists today. The Hydrographic Office and the Naval Observatory were transferred to the Office of the Chief of Naval ...
Bound copy, from the 1980s, of the MIL-STD-1750A specification document. The 1750A supports 2 16 16-bit words of memory for the core standard. The standard defines an optional memory management unit that allows 2 20 16-bit words of memory using 512 page mapping registers (in the I/O space), defining separate instruction and data spaces, and keyed memory access control.
The FLAGS register is the status register that contains the current state of an x86 CPU.The size and meanings of the flag bits are architecture dependent. It usually reflects the result of arithmetic operations as well as information about restrictions placed on the CPU operation at the current time.
AMD's 64-bit extension to the original instruction set make relatively few changes to 32-bit addressing, with the most significant being that in long mode, 64-bit addressing is the default. 64-bit registers (RAX, RBX, RCX, etc.) are used rather than 32-bit registers for address computation. The displacement is not widened to 64 bits; MOD=11 ...
