摘要:
A computing apparatus includes a primary keyboard and a primary display, which are respectively arranged to accept input from a user and to display information to the user. An auxiliary display is arranged to display auxiliary information to the user when the apparatus is in a switched-off operational state, and to hide the auxiliary information when deactivated. An activation controller is arranged to monitor the primary keyboard when the auxiliary display is deactivated, to detect an activation code comprising one or more keystrokes entered using the primary keyboard, and to activate the auxiliary display responsively to detecting the activation code.

A computing apparatus includes a display, a Central Processing Unit (CPU) having active and switched-off operational states and an auxiliary display controller, which is active when the CPU is in the switched-off operational state. The computing apparatus further includes a switch, which is operative to connect the CPU to the display when the CPU is in the active operational state, so as to display first information produced by the CPU, and to connect the auxiliary display controller to the display when the CPU is in the switched-off operational state, so as to display second information produced by the auxiliary display controller.

A computing apparatus includes a network interface, a Central Processing Unit (CPU), an auxiliary controller and an activation controller. The CPU has active and switched-off operational states and is arranged, when operating in the active operational state, to accept data from a communication network using the network interface. The auxiliary display module is connected to the CPU and is arranged, when the CPU is in the switched-off operational state, to display auxiliary information to a user based on the data accepted by the CPU. The activation controller is coupled to intermittently switch the CPU to the active operational state and to cause the CPU to update the data from the communication network, so as to update the auxiliary information displayed by the auxiliary display module.

An embedded controller includes a microcontroller core, a first bus interface that does not support bus arbitration, a second bus interface and memory control circuitry. The first bus interface is configured to receive and transmit memory transactions from and to a Central Processing Unit (CPU) chipset. The second bus interface is configured to communicate with a memory and to transfer the memory transactions of the CPU chipset to and from the memory. The memory control circuitry is configured to evaluate a starvation condition that identifies an inability of the microcontroller core to access the memory via the second bus interface due to the memory transactions transferred between the CPU chipset and the memory via the first and second bus interfaces, and to invoke a predefined corrective action when the starvation condition is met.

A method for implementing an MD5 algorithm on an 8-bit micro-controller includes providing a pointer to an entry in a table stored in a read only memory (ROM). The entry corresponds to an operation in the MD5 algorithm. The method also includes retrieving from the entry at least one pointer to at least one variable required for the operation. In addition, the method includes performing the operation.
摘要:
In a computer system that includes processing, memory and I/O modules and ACPI for outputting an ONCTL signal to a power supply unit. The power supply is configured to output a power off signal indicative of power off state and power on signal indicative of power on state. There is provided an embedded controller coupled to the ACPI and to the power supply unit. The embedded controller includes input for receiving a shut off event and in response to the shut off event, feeding to the ACPI a controller power off signal as long as the power supply is in power on state.
