A secure memory system and a method of maintaining the security of memory contents. One embodiment of the system includes: (1) a security control module configured to transmit a system memory secure mode signal and processor secure mode signal to place the system in a secure mode, (2) a secure memory bridge coupled to the security control and system memory and configured to encrypt and decrypt data associated with the system memory based on a state of the system memory secure mode signal and (3) a boot processor coupled to the security control module and the secure memory bridge and configured to transmit requests to the secure memory bridge in the secure mode and an unsecure mode.

System and method for maintaining the security of memory contents and computer architecture employing the same

The invention is a method and apparatus for ensuring synchronization for digital communication between a transmitting and a receiving device, particularly when the clock and/or frame synchronization is sourced from a different location than the transmit data.

Method and apparatus for synchronizing data transfer

A synchronization method and apparatus for detecting and synchronizing asynchronous signal data pulses. The synchronization system passes individual data pulses through two parallel synchronization sub-circuits, alternating synchronization sub-circuits for each succeeding pulse, and combines the output of the parallel synchronization sub-circuits to create a single synchronous signal.
