Need help in Qemu source code

[anselme taf]

Hello dear team
I'm working on Qemu's source code, mainly on Qemu's CPU. I need you to
enlighten me on a number of points
1- How does Qemu emulate its different processors, Can I have a
diagram that describes how Qemu emulates?
2- How is the Qemu x86 CPU implemented?
3- Can I bring out a diagram?
4- How to display the TLB, the registers, the cache ...?
5- How are implemented and where are the data structures of cache,
registers and ALU?
6- How can I go about it if I have to inject faults into caches,
registers and ALU?
Thank you,
