Intel ME equivalent in Apple Silicon

So AMD and Intel have built-in autonomous subsystems that have the ability to spy on users (IME and PSP). I heard that Apple has some new thing that scans the files that users store on their servers to look for illegal photographs, and I speculate that will soon be used to look for more than crime. But besides this, is it known that Apple has any other spying —ware in the Apple Silicon Mac? I’m not asking ‘whether it is likely full of spying devices’, but rather ‘which spying services that are known on Apple silicon’.
