Abstract: This disclosure describes a programmable clock configuration block disposed at the SoC system, which manages clock frequency change flow in a single clock domain on a SoC system to provide dynamic clock frequency configuration while the SoC system is in operation. The programmable clock configuration block is configured to interact with the CPU of the SoC system to configure or change parameters relating to the clock signal frequency while the CPU is in an inactive state.

Abstract: A device for protecting secured areas in a computer system which includes at least one storage unit divided into at least two storage areas. The device includes input-output (I/O) interfaces for connecting between the computer system and the storage unit, a managing controller connected to the I/O interfaces and communication interfaces connected to the managing controller, for linking between the computer system and communication networks. The managing controller provides the computer system with a selection between at least two modes. In each mode, the managing controller provides access to and from the computer to selected storage areas and communication networks. Furthermore, in each mode, the managing controller denies or provides limited access to and from the computer to non-selected storage areas and communication networks.

Abstract: Method for selectively connecting computer stations to a plurality of communication devices, including the steps of receiving a connection request from a computer station to connect to a requested one of said plurality of communication devices, disconnecting the selected computer station from all of the communication devices, detecting if the selected computer station is configured according to the requested communication device, and connecting the selected computer station to the requested communication device, when the selected computer station is configured according to the requested communication device.

Abstract: Communication apparatus including a public network, a secured network, a plurality of public nodes connected to the public network and a plurality of secured nodes connected to the secured network and to the public network. The nodes including interfaces for communicating therebetween over the networks, wherein each the secured node includes a communication controller a computer system and a secured storage area. A secured node divides a confidential message into at least two segments and transmits the segments via the networks wherein at least a selected one of the segments is transmitted via at least one of the secured networks. The communication controller is also operative to disconnect the secured storage area from the computer station and the public network when the communication between the computer station and the public network is in progress.
