Question ROM as the place microcode is stored |

Line 342:
:::::{{quote|The decoders translate x86 instructions into uops. P6 uops have a fixed length of 118 bits, using a regular structure to encode an operation, two sources, and a destination. The source and destination fields are each wide enough to contain a 32-bit operand. Like RISC instructions, uops use a load/store model; x86 instructions that operate on memory must be broken into a load uop, an ALU uop, and possibly a store uop.}}
:::::which is a description of a "generate micro-operations on the fly" processor, not a traditional "microcode as instruction set simulator" processor. [[User:Guy Harris|Guy Harris]] ([[User talk:Guy Harris|talk]]) 09:29, 20 July 2022 (UTC)
== Overview/Microcode ==
The '''Microcode''' subsection within the '''Overview''' section contains the following:
''Using microcode, all that changes is the code stored in the associated read only memory (ROM). This makes it much easier to fix problems in a microcode system. It also means that there is no effective limit to the complexity of the instructions, it is only limited by the amount of ROM one is willing to use.''
Since microcode can be updated, is it actually stored in ROM? I presume the answer is, "No," but I don't know what type of memory should be mentioned, so I didn't change the text.
