How to find Intel 8080 instruction decoder schematic?

Question

assembler

Hello. Please help. I study the essence of the processor. Earlier I asked a question about the length of the instruction ( How does the processor recognize the length of the instruction? ). As I understand it, using the "command decoder" the processor recognizes the length of the command. I want to understand the essence of the work of the "instruction decoder" for the Intel 8080 (namely, how the decoder recognizes operands for 2 or 3 byte commands (the condition for recognizing and writing operands) and how the transition to the next command is carried out after 2 or 3 byte commands). But I could not find the decoder circuit. How to find the Intel 8080 instruction decoder diagram?
Preferably with a link, if available. Thanks in advance!

Answer 1

For starters, the 8080 is a commercial Intel processor. Not an open source product. It is possible that no one has published schemes and instructions, which may well still be protected by trade secrets and patents. You can try to get a job at intel and study archival documents there.
Secondly, have you tried just looking?
even the wiki has useful links

Answer 2

Here is some kind of 8080 emulator on python, there in the code there are links to instructions and so on.
