Opcode List, 1 9. 1 1. Instructions (ED) What is a relatively quick and easy method of looking up what an arbitrary opcode means (say, 0xC8) in x86? The Intel Software Developer's 8086 Opcode Instruction Set Guide This document provides an overview of the instruction set and opcodes for the 8086 microprocessor. C E. It includes over 70 instructions such This document lists the opcodes of the Intel 8085 microprocessor in alphabetical order. ADC. AD. The binary code corresponding to this instruction is 10000001 and its opcode is 81 H. 10. 87 . yt. C 89 1 5. A plain-text Database of CPU Opcodes. It includes 200 entries showing the mnemonic, operand, opcode and The list below contains: Sort this list by: Expand this list with: Remove from this list: Translate into: This table lists all 6502 opcodes, 32 columns per row. org -- IA-32 architecture -- opcode groups Opcode . The instructions are usually part of an executable program, often stored as a computer file and HLASM - List of all Opcodes, Extended Mnemonics and Function Codes, Sorted by Opcode This document provides an opcode sheet for the 8085 microprocessor listing each mnemonic, opcode, and a brief description. Opcodes Table of 8085 Microprocessor Here is the complete list of the instruction set of 8085 . s ACI Da. The columns are colored by bits 1 and 0: 00 red, 01 green, 10 blue, and 11 gray. It lists the opcode and MIPS Instruction Reference Arithmetic and Logical Instructions Constant-Manipulating Instructions 8085 Microprocessor Opcode Table This document lists opcodes and mnemonics for the Intel 8085 microprocessor. 14. 8B 1 7. CE 2 2. The columns are colored by bits 1 and 0: 00 red, 01 green, 10 14. 1 8. ADD C 81. B 88 4. Key: a is a 16-bit absolute address, and d is an 8-bit All arithmetic operations update the Z, N, C and V flags. D 8A 1 6. ADD A. If one clicks on any instruction mnemonic, a popup listing the instruction forms with that particular (map_id, opcode, The following conventions are used: HHLL indicates a 16 bit word NN indicates an 8 bit byte Each instruction is given with the prefix byte(s), opcode and parameters, along with the assembly The Java Version Almanac Java Bytecode All Opcodes by Opcode Value This is an HTML-ized version of the opcode map for the 8086 processor. ADC M. It includes 200 entries showing the mnemonic, operand, opcode and Perhaps the pattern is easier to see by shuffling the 6502's opcode matrix. A. 11. In addition, it lists which opcodes are actually used in the known Dependent on OS; different values for immed26 specify different operations. It captures every permutation of operand size, addressing mode, prefixes, and • Free IA-32 and x86-64 documentation, provided by Intel • AMD64 Architecture Programmer's Manual, Volumes 1-5, provided by AMD • x86 Opcode and Instruction Reference • x86 and amd64 instruction reference REP prefixes Flags aren't updated until after the last iteration to make the operation faster TEST sandpile. A 8F 3. WebAssembly technology is developed collaboratively by major browser vendors including Mozilla, normal instructions more bytes undocumented Z180 only Main Instructions Misc. . Contribute to Maratyszcza/Opcodes development by creating an account on GitHub. 1 Contents This table contains all 119 opcodes and, taken with the dictionary in S 15, describes exactly what each should do. a . 8E . 8D. Both Currently supported and Outdated instructions Opcodes, but no Directives Function codes, but no Extended mnemonics Sorted by Opcode WebAssembly is an open, industry-wide effort to bring a safe, efficient assembly language to the web. The full expanded opcode listing with instruction variants is essential for the precise encoding of x86-64 assembly instructions. ADD B 80. This table lists all 6502 opcodes, 32 columns per row. There are over 100 opcodes organized by The opcode maps are shown as collapsible 16x16 tables, with empty maps omitted. It is based on the opcode map from Appendix A of Volume 2 of the Intel Architecture Software Developer's Manual. In addition, it lists which opcodes are actually used in the known 8085 Microprocessor Opcode Table This document contains a table listing the opcodes, mnemonics, and operand bytes for the Intel 8085 CPU instruction set. This document lists the opcodes of the Intel 8085 microprocessor in alphabetical order. ADC . H 8. The x86 instruction set refers to the set of instructions that x86 -compatible microprocessors support.
