2. Intel BCD opcodes - Wikipedia

   en.wikipedia.org/wiki/Intel_BCD_opcodes

   Adding BCD numbers using these opcodes is a complex task, and requires many instructions to add even modest numbers. It can also require a large amount of memory. [ 2 ] If only doing integer calculations, then all integer calculations are exact, so the radix of the number representation is not important for accuracy.

3. x86 instruction listings - Wikipedia

   en.wikipedia.org/wiki/X86_instruction_listings

   New opcodes that introduced new functionality (e.g. SHLD, SETcc) For instruction forms where the operand size can be inferred from the instruction's arguments (e.g. ADD EAX,EBX can be inferred to have a 32-bit OperandSize due to its use of EAX as an argument), new instruction mnemonics are not needed and not provided.

5. x86 assembly language - Wikipedia

   en.wikipedia.org/wiki/X86_assembly_language

   x86 assembly language is a family of low-level programming languages that are used to produce object code for the x86 class of processors. These languages provide backward compatibility with CPUs dating back to the Intel 8008 microprocessor, introduced in April 1972.

6. Ralf Brown's Interrupt List - Wikipedia

   en.wikipedia.org/wiki/Ralf_Brown's_Interrupt_List

   Ralf Brown's Interrupt List (aka RBIL, x86 Interrupt List, MS-DOS Interrupt List or INTER) is a comprehensive list of interrupts, calls, hooks, interfaces, data structures, CMOS settings, memory and port addresses, as well as processor opcodes for x86 machines from the 1981 IBM PC up to 2000 (including many clones), [1] [2] [nb 1] most of it still applying to IBM PC compatibles today.

7. 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 ...
