Abstract: A System-on-Chip (SoC) includes a communication processor, an application processor that sets a secure mode of the communication processor through a control bus, and an access control unit that sets or changes an access control of the communication processor, based on an address region and an access permission of the communication processor. The SoC performs access control operations of respective hardware blocks, through an access control unit. When various systems are integrated in one system-on-chip, an access control operation is performed according to the secure attributes and access permissions of the systems.

Abstract: A display system comprises a first display device configured to transmit information associated each of with multiple frames in slice units, and a second display device configured to receive the information from the first display device. Where a latency of at least one slice of a selected frame among the multiple frames exceeds a predetermined time, the first display device skips a transfer operation of at least one frame among the multiple frames.
