Firstly I am not sure if this is the right place to ask this. If anyone has any idea of where this question belong please tell me.
Recently I was reading about TPM and TSS(TPM Software Stack). The diagram in this document -- TSS TAB and Resource Manager Specification shows the structure of the stack. In my understanding, the TCTI and stacks above is in the library to communicate with TPM; where TAB and stacks below TAB are in the real TPM or virtual TPM device. But I am not sure if my understanding is correct.
My question is: Is there a TAB/RM component (or component with similar responsibility) in a real TPM device? Or does tbs/some modules in OS take this resposibility?
