摘要: A method of extending trust from a trusted processor to a graphics processing unit to expand trusted processing in an electronic device comprises inserting a trusted kernel into the graphics processing unit, monitoring the activity level of the graphics processing unit, suspending graphics processing on at least a portion of the graphics processing unit, repurposing a portion of the graphics processing unit to perform trusted processing, and releasing the portion of the graphics processing unit from trusted processing.
