A peripheral interface circuit and a peripheral memory system are provided. The peripheral interface circuit includes an interface sequencer, an input/output controller, a register unit and a data buffer. The interface sequencer receives requests from the input/output controller and accesses the peripheral memory in response to the requests. The data buffer is randomly accessed by address. If target data of the data access request exists in the data buffer, the input/output controller returns data from the data buffer in response to the request; if target data of the data access request does not exist in the data buffer, the input/output controller sends an interface request to the interface sequencer to access the peripheral memory and keeps a copy of at least the target data in the data buffer.

Peripheral interface circuit

The present invention discloses a method for software-hardware authentication of an electronic apparatus includes receiving a challenge string (CS) from the electronic apparatus through a challenge string input port (CSIP). The challenge string is a string of trace data generated according to some operations of software running on the electronic apparatus. An authentication result for use in an authentication process for the software to authenticate a hardware unit of the electronic apparatus or for the hardware unit to authenticate the software is generated according to the string of the trace data. The authentication process is performed according to the generated authentication result.
