CPU Registers x86-64 - OSDev Wik

1. Extended Feature Enable Register (EFER) is a model-specific register added in the AMD K6 processor, to allow enabling the SYSCALL/SYSRET instruction, and later for entering and exiting long mode. This register becomes architectural in AMD64 and has been adopted by Intel. Its MSR number is 0xC0000080
2. x86-64 has a total of 6 segment registers: CS, SS, DS, ES, FS, and GS. The operation varies with the CPU's mode: In all modes except for long mode, each segment register holds a selector , which indexes into either the GDT or LDT
3. x64 extends x64's 8 general-purpose registers to be 64-bit, and adds 8 new 64-bit registers. The 64-bit registers have names beginning with r, so for example the 64-bit extension of eax is called rax. The new registers are named r8 through r15
4. The x64 ABI considers the registers RAX, RCX, RDX, R8, R9, R10, R11, and XMM0-XMM5 volatile. When present, the upper portions of YMM0-YMM15 and ZMM0-ZMM15 are also volatile. On AVX512VL, the ZMM, YMM, and XMM registers 16-31 are also volatile
5. g, and much more)

With 64-bit mode and the new paging mode, it supports vastly larger amounts of virtual memory and physical memory than was possible on its 32-bit predecessors, allowing programs to store larger amounts of data in memory. x86-64 also expands general-purpose registers to 64-bit, and expands the number of them from 8 (some of which had limited or fixed functionality, e.g. for stack management) to 16 (fully general), and provides numerous other enhancements Addressing in x86-64 can be relative to the current instruction pointer value. This is indicated with the RIP (64-bit) and EIP (32-bit) instruction pointer registers, which are not otherwise exposed to the program and may not exis

How many registers does an x86-64 CPU have

There are extensions that certain AMD64 based CPUs support/implement that extend the set of XMM registers available. The XMM (and later YMM and ZMM) are currently extended to up to 32 registers of 512 bit each in AVX-512. Similar to general registers, XMM registers allow access to the lower parts of their YMM and ZMM counterparts It should be noted that it was not Intel that increased the number of registers in x64 and named them, but AMD, as the 64-bit extensions to x86 were created by AMD. Intel's 64-bit design was Itanium , which hasn't done quite so well, though they did put a lot (128 general purpose integer, plus many others) of registers in it. - 8bittree Nov 20 '15 at 16:2

Floating-Point and SIMD Registers. x86_64 also defines a set of large registers for floating-point and single-instruction/multiple-data (SIMD) operations. For details, refer to the Intel or AMD documentation. Instructions Starter Kit. These instructions are sufficient to complete the SPO600 Assembler Lab (GAS syntax) Open-source. Intuitive and familiar, yet new user interface. C-like expression parser. Full-featured debugging of DLL and EXE files (TitanEngine) IDA-like sidebar with jump arrows. IDA-like instruction token highlighter (highlight registers, etc.) Memory map Reference. This handout only mentions a small subset of the rich possibilities provided by the x86-64 instruction set and architecture. For a more complete (but still readable) introduction, consult The AMD64 Architecture Programmer's Manual, Volume 1: Application Programming.. Registers Die gelb hinterlegten Register R8-R15 und XMM8-XMM15 stehen ausschließlich im 64-Bit-Modus zur Verfügung. Die Register RAX-RSP sowie RFLAGS und RIP sind im 32-Bit-Modus nur 32 Bit groß und heißen dort EAX-ESP, EFLAGS und EIP, wie schon beim 80386. Der Zugriff auf die 64-Bit-Register erfolgt über neu eingeführte Befehlspräfixe The x64 architecture is the evolution of the older x86 architecture, it kept compatibility with its predecessor (x86 registers are still available) but it also introduced new features: Registers have now a capacity of 64 bits; There are 8 more general-purpose registers; Segment registers are forced to 0 in 64 bits mode

Registers galore x86 has just 8 general-purpose registers available (eax, ebx, ecx, edx, ebp, esp, esi, edi) . x64 extended them to 64 bits (prefix r instead of e) and added another 8 (r8, r9, r10, r11, r12, r13, r14, r15) I need to determine whether an architecture is 32-bit or 64-bit in order to install the correct remote access client. I don't have the option to use anything else, so I need to get that information out of the Registry somehow, and I can't use any scripting technologies to do it ordinary integer x86 registers. The 64 bit registers are shown in red. Scratch registers any function is allowed to overwrite, and use for anything you want without asking anybody. Preserved registers have to be put bac REX prefixes allow a 64-bit operand to be specified when operating in 64-bit mode. By using this mechanism, many existing instructions have been promoted to allow the use of 64-bit registers and 64-bit addresses. The description of Compatibility Mode is ommitted on purpose, because this mode is virtually identical to 32-bit protected mode. Note

• I discovered there is a registry value that holds this information under: HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment. The PROCESSOR_ARCHITECTURE string data will either be AMD64 (meaning 64-bit) or x86 (meaning 32-bit). This is the same for both Intel and AMD hardware.

• Nowadays, you can use 64 bit registers for only their lower byte or word without worrying about not having enough registers. Cost of increasing instruction set Since the available instruction set was relatively small and there were only a few registers, enough of bits were available to encode the different half of registers without increasing the size of the instruction set
• 64-bit Registers. A 64-bit register is made by concatenating a pair of 32-bit registers. This is shown by putting a colon between them. The most common 64-bit register (used for operations such as division and multiplication) is edx:eax

Each register to be used is pushed onto the stack one at a time, and the compiler must remember what it did so it can unwind it later. Allocate local variables The function may choose to use local stack-based variables, and they are allocated here simply by decrementing the stack pointer by the amount of space required How to Register an ActiveX DLL using regsvr32 (Also see the ActiveX DLL Registration Tutorial). The first step is to determine if you need to register the ActiveX DLL compiled for 32-bit or 64-bit 64-bit registers. Without address pre xing, the code usually defaults to 32-bit accesses to registers and memory, except for the stack which is always 64-bit aligned and jumps. 32-bit operations on 64-bit reg-isters do zero extension. 64-bit immediates are only supported by the new movabs instruction.

The same is true of 32-bit CPUs (32-bit registers), 16-bit CPUs, and so on. 3 Registers are very fast to access and are often the operands for arithmetic and logic operations. The x86 family has a number of general and special purpose registers COM object types are registered via registry keys. This is what the regasm.exe utility does (writes to the registry). 32-bit bit registry nodes and distinctly different than 64-bit registry nodes. That is why the .NET framework comes with 2 versions of regasm.exe.
