The '''AMD Platform Security Processor (PSP)''', also known as the '''AMD Secure Processor''', is an autonomous processor embedded on most modern AMD CPU's since 2013. The PSP has full access to memory and is capable of running without the main CPU cores being active.<ref>{{Cite web |last=Eichner |first=Alexander |last2=Buhren |first2=Robert |date=2020-08-05 |title=All you ever wanted to know about the AMD Platform Security Processor and were afraid to emulate |url=https://i.blackhat.com/USA-20/Wednesday/us-20-Buhren-All-You-Ever-Wanted-To-Know-About-The-AMD-Platform-Security-Processor-And-Were-Afraid-To-Emulate.pdf |url-status=live |access-date=2026-02-04 |website=blackhat.com}}</ref> | The '''[[AMD]] Platform Security Processor (PSP)''', also known as the '''AMD Secure Processor''', is an autonomous processor embedded on most modern AMD CPU's since 2013.
