Method and system to allow system-on-chip individual I/O control to be disabled and enabled by programmable non-volatile memory

摘要

Certain aspects of a method and system for allowing system-on-chip individual I/O control to be disabled and enabled by programmable non-volatile memory are disclosed. Aspects of one method may include mapping at least one bit of a control vector within a security processor comprising a non-volatile memory to each of a plurality of on-chip I/O physical buses. At least one of the plurality of on-chip I/O physical buses may be enabled or disabled by modifying the mapped bit or bits of the control vector.

1. A method for secure communication, the method comprising:
mapping, using a security processor, a first bit of a multibit control vector stored in a non-volatile memory to a first input/output (I/O) physical bus in a plurality of on chip I/O physical buses; mapping, using the security processor, a second bit of the multibit control vector to a second I/O physical bus in the plurality of on chip I/O physical buses; and controlling operation of the first I/O physical bus and the second I/O physical bus by modifying the mapped first and second bits of the multibit control vector.
