WebOct 20, 2024 · The Intel x86 processor uses complex instruction set computer (CISC) architecture, which means there is a modest number of special-purpose registers instead of large quantities of general-purpose registers. It also means that complex special-purpose instructions will predominate. The updated instruction set is also grouped according to architecture (i386, i486, i686) and more generally is referred to as (32-bit) x86 and (64-bit) x86-64 (also known as AMD64). Original 8086/8088 instructions See more The x86 instruction set refers to the set of instructions that x86-compatible microprocessors support. The instructions are usually part of an executable program, often stored as a computer file and executed on the … See more • Free IA-32 and x86-64 documentation, provided by Intel • x86 Opcode and Instruction Reference See more x86 also includes discontinued instruction sets which are no longer supported by Intel and AMD, and undocumented instructions which execute but are not officially documented.

WebAMD64 est le nom de l'architecture des premiers microprocesseurs 64 bits de la société Advanced Micro Devices.Son nom de code est Hammer (de l'anglais marteau) remplaçant l'appellation x86-64.Le nom x86-64 est généralement utilisé lorsque l'on parle de ce jeu d'instructions, sans faire référence à la marque AMD. En effet, si dans un premier temps … WebInstruction Opcodes. 8.2. Instruction Opcodes. The OP field in the Nios II instruction word specifies the major class of an opcode as listed in the two tables below. Most values of OP are encodings for I-type instructions. One encoding, OP = 0x00, is the J-type instruction call. Another encoding, OP = 0x3a, is used for all R-type instructions ... stheno w101

Registers x64 extends x86'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". For example, the 64-bit extension of eax is called rax. The new registers are named r8 through r15. WebThe IA-32 is the instruction set architecture (ISA) of Intel’s most successful line of 32-bit processors, and the Intel 64 ISA is its extension into 64-bit processors.
