	NX bit - Wikipedia, the free encyclopedia
		Generically, it is a technology used in CPUs to segregate areas of memory for use by either storage of processor instructions (aka code) or for storage of data.
		Linus Torvalds has taken an interest in the NX patch, and believes it may be wise to have NX enabled by default; thus, it has been merged into the kernel in the 2.6.8 release.
		Outside of the x86 sphere, a version of NX also exists for Intel's IA-64 which is implemented into the Windows that operates that architecture.

	Security Ahoy! Flying the NX Flag on Windows and AMD64 To Stop Attacks
		NX, which stands for "No Execute Bit," is a one-bit flag that goes with each entry in the memory address table.
		The NX data/executable check is similar to other run-time testing the processor does to ensure that non-privileged (user) code can't access privileged (supervisor) code and data, and to prevent writes into read-only address spaces.
		NX support is also going to be a part of Windows Server 2003 Service Pack 1 (you can download the second release candidate), and the forthcoming 64-bit versions of Windows XP and Windows Server 2003.

	AMD64 - Wikipedia, the free encyclopedia
		The AMD64 instruction set is currently implemented in AMD's Athlon 64, Athlon 64 FX, Athlon 64 X2, Turion 64, Opteron and later Sempron processors.
		AMD's x86-64 instruction set (later renamed AMD64) is an extension of Intel's IA-32 (x86-32) architecture, created as an alternative to Intel and Hewlett Packard's radically different IA-64 architecture which has received a relatively cool market reception in many market sectors, and which was protected from cloning by a number of patents.
		SSE instructions: The original AMD64 architecture adopted Intel's SSE and SSE2 as core instructions.

	CPU-Based Security: The NX Bit
		Basically, NX uses processor hardware to discourage the kind of virus, worm, and Trojan Horse attacks seen in scourges such as Blaster, Sasser, and Code Red, which have cost companies billions of dollars in downtime and disinfectant chores.
		Intel is expected to add NX (or XD) to the next generation of its 90-nanometer-process Pentium 4 "Prescott" CPUs -- bundling the security enhancement with a larger 2MB Level 2 cache and perhaps a faster 1066MHz front-side bus -- in the fourth quarter of this year.
		And VIA Technologies promises that NX support will be part of its forthcoming C5J "Esther" core, the IBM-manufactured, 90-nanometer, silicon-on-insulator successor to today's power-thrifty C3 processor; the C5J is planned to offer clock speeds up to 2GHz with a front-side bus up to 800MHz, but no ship date has been announced yet.

	UGS: About Us: Customer Case Studies and Videos: MAN B&W Diesel
		Instruction books were used for up to 10 years before they were updated or replaced.
		When the Instruction Books Department used the previous CAD system, generic part drawings were frequently re-used for different engines because it was too much work to create a new one each time.
		Another benefit of using NX for instruction books - and of working from existing NX component and assembly models - is that instruction book documents are ready months before the engine itself.

	AMD64
		AMD's x86-64 instruction set (later renamed AMD64), is an ambitious attempt to clean up the idiosyncrasies of Intel's x86-32 architecture, and update the x86 architecture to a format more closely resembling leading edge 64 bit RISC environments.
		Instructions can now reference data relative to the program counter, which makes code in shared libraries that are not compiled to a fixed address more efficient.
		It should be noted that the NX bit has long been available on 32-bit x86 processors in the PAE (Paged Addressing Environment) mode, originally introduced in the 80286 processor.

		instruction actually returns into a general purpose instruction that transfers control into a controllable buffer that contains the arbitrary code to be executed now that NX support has been disabled.
		instruction is executed which transfers control into the shellcode that immediately follows it.
		The second dependency could be broken by moving the logic that controls the enabling and disabling of a process' NX support to kernel-mode such that it cannot be influenced in such a direct manner.

	Transmeta pledges 'no execute' security support
		Transmeta today claimed that its Efficeon chip will be the first "energy-efficient" processor to support the oft-touted 'no execute' NX instruction required by Windows XP Service Pack 2's anti-virus sub-system.
		Either way, adding NX will allow Windows XP SP2 to prevent viruses and worms from executing code stored in areas memory marked for data rather than executables.
		Transmeta is this month providing Microsoft with advance versions of Efficeon-based systems with NX support for internal evaluation and use, the chip maker said.

	TINY BASIC experimenter's kit
		When an INPUT instruction in BASIC is interpreted, the two pointers are exchanged by the SB opcode so that the expression handling capabilities of the interpreter may be applied to the input data, then the pointers are restored (exchanged again) by the RB.
		The memory bounds and stack pointers are reset by this instruction to signify an empty program space, and the line number of the first line is set to zero, which is the indication of the end of the program.
		This instruction must be executed at least once before the first execution of a NX instruction.

		The default is to disallow straddling a 256-byte boundary.
		A pseudo-op `.c185_loop_back_okay' can be used before the end-of-loop truncate/fix instruction, if the programmer knows that the next instruction and the instruction at the top of the loop do not have an FPA with a bypassable input from the ftruncate/fix result.
		A pseudo-op `.c186_loop_okay' can be used after the loop instruction and before the C&A to prevent the NOP from being inserted, if the programmer knows that the loop is not terminated with an double precision FP operation (or a C&A containing such).

	Protect Your Vista App with AMD Enhanced Virus Protection
		NX only protects against jumping to code in a data page; it doesn't keep a stack overwrite from sending a program off to a Windows function inside a system DLL that might further the attacker's aims.
		For NX to be applied to a given executable, three conditions must be met.
		And finally, Vista has to mark all of the program's non-code pages with the NX flag, which is determined by the operating environment (32-bit or 64-bit Vista), boot configuration options, and the program itself.

	Einbau
		Mounting the nitrous nozzle was made easy by NX due to the supplied specially made nozzle fitting, which when used, prevents any chance of the nozzle backing out.
		The installer chose a rubber grommet located on the passenger side of the firewall to route the NX feed line from the engine compartment to the trunk.
		Although many people feel that wiring such as this should be left for a professional, NX has made their instructions very user friendly for the novice.

		If the most recent in-theory instruction in the current state of the proof-checker has no arguments, or if there is no in-theory instruction in the current state of the proof-checker, then the proof-checker will use the current ACL2 theory.
		Finally, as each instruction in instruction-list is executed, the prompt and that instruction will be printed, unless the global state variable print-prompt-and-instr-flg is unbound or nil and the parameter no-prompt-flg is supplied and not nil.
		Then after invoking the instruction (dive 2 1), so that the current subterm is (g x), followed by the instruction x, we would expect the conclusion to be (if (integerp x) (equal 3 3) t).

	Nikon Capture NX Software First Look Review (Site not responding. Last check: 2007-10-03)
		Although Nikon Capture NX is ideally geared towards post processing the Nikon Electronic Format (NEF) files created by such cameras as the Nikon D50, Nikon D70s and Nikon D200 digital SLR's, for the first time, Nikon Capture version NX processing can now be applied to JPEG and TIFF images.
		One of the most unique and powerful features of NEF is the ability to utilize Nikon Capture NX to process the image with the camera settings that you assigned within the camera using Nikon processing algorithms to produce the highest possible image quality.
		From what we have been able to see from Nikon Capture NX so far, we are very impressed with the simplicity of the user interface and the intuitiveness of the editing process.

	Gamasutra - Features - Hard Targets Online - "Cracking Open The Pentium III" [05.28.99]
		The only inconvenient aspect of this tool is that when a breakpoint is first hit, an int 3 instruction (debugger break) is shown in the disassembly window, and you have to enter the first byte of actual instruction if you want an accurate disassembly.
		Usually for a SIMD instruction, the first byte will be 0x0f for packed scalar instructions and 0xf3 for single scalar instructions.
		The single square root and divide instructions are faster than the packed ones, and replacing the last two instructions in the above example with the four instructions below will save around 40 cycles, making this code about twice as fast as the equivalent x87 floating-point code.
