2. x86 instruction listings - Wikipedia

   en.wikipedia.org/wiki/X86_instruction_listings

   Opcode AAA: ASCII adjust AL after addition: used with unpacked binary-coded decimal: 0x37: AAD: ASCII adjust AX before division: 8086/8088 datasheet documents only base 10 version of the AAD instruction (opcode 0xD5 0x0A), but any other base will work. Later Intel's documentation has the generic form too.

3. Minimal instruction set computer - Wikipedia

   en.wikipedia.org/wiki/Minimal_instruction_set...

   Minimal instruction set computer (MISC) is a central processing unit (CPU) architecture, usually in the form of a microprocessor, with a very small number of basic operations and corresponding opcodes, together forming an instruction set. Such sets are commonly stack-based rather than register-based to reduce the size of operand specifiers.

4. NOP (code) - Wikipedia

   en.wikipedia.org/wiki/NOP_(code)

   Opcode for OR 0,0,0. [6] LDI 26,0: 4 0x34000034 Palindromic NOP - that is, an instruction that executes as NOP regardless of whether byte order is interpreted as little-endian or big-endian. Some PA-RISC system instructions are required to be followed by seven palindromic NOPs. [6] PowerPC: NOP: 4 0x60000000 (extended opcode for ori r0,r0,0)

5. Simple-As-Possible computer - Wikipedia

   en.wikipedia.org/wiki/Simple-As-Possible_computer

   The instruction set architecture (ISA) that the computer final version (SAP-3) is designed to implement is patterned after and upward compatible with the ISA of the Intel 8080/8085 microprocessor family. Therefore, the instructions implemented in the three SAP computer variations are, in each case, a subset of the 8080/8085 instructions.

6. Opcode table - Wikipedia

   en.wikipedia.org/wiki/Opcode_table

   An opcode table (also called an opcode matrix) is a visual representation of all opcodes in an instruction set. It is arranged such that each axis of the table represents an upper or lower nibble, which combined form the full byte of the opcode. Additional opcode tables can exist for additional instructions created using an opcode prefix.

7. Machine code - Wikipedia

   en.wikipedia.org/wiki/Machine_code

   Most instructions have one or more opcode fields that specify the basic instruction type (such as arithmetic, logical, jump, etc.), the operation (such as add or compare), and other fields that may give the type of the operand(s), the addressing mode(s), the addressing offset(s) or index, or the operand value itself (such constant operands ...

8. Intel 8085 - Wikipedia

   en.wikipedia.org/wiki/Intel_8085

   The Intel 8085 ("eighty-eighty-five") is an 8-bit microprocessor produced by Intel and introduced in March 1976. [2] It is the last 8-bit microprocessor developed by Intel. It is software- binary compatible with the more-famous Intel 8080 with only two minor instructions added to support its added interrupt and serial input/output features.

9. Prefetch input queue - Wikipedia

   en.wikipedia.org/wiki/Prefetch_input_queue

   Fetching the instruction opcodes from program memory well in advance is known as prefetching and it is served by using a prefetch input queue (PIQ). The pre-fetched instructions are stored in a queue. The fetching of opcodes well in advance, prior to their need for execution, increases the overall efficiency of the processor boosting its speed ...
