  • Patent number: 6618813
    Abstract: A method for suspending and resuming a computer system without being affected by an abnormal power failure. The relevant operating information and context of the related devices are stored in both a memory and a hard disk before the computer system enters into a sleep state. If a power failure occurs, relevant operating information of the system can still be fetched from the hard disk to restore the computer system to its original operating state even though the information saved in the memory is lost. Also, the computer system can self turn on and activate a “wake on LAN” function and a “ring in wake up” function when power resumes after a sudden power failure before entering into the soft-off state. Therefore, users and system administrator can wake up the computer system from a remote site in a very convenient way.

  • Patent number: 6598102
    Abstract: In this invention, serial transmission suitable for signal lines in which a transformer is inserted is realized by using existing differential buffers. Differential output buffers are connected in parallel with each other. A differential signal line pair in which a transformer is inserted is driven by these two differential output buffers. In this case, a voltage between the two lines of the differential signal line pair is determined by a combination of outputs from the two differential output buffers, and three values, i.e., “+V”, “−V”, and “zero”, can be output. By using this ternary data, serial signal transmission based on the bipolar transfer mode can be performed, and serial transmission suitable for the signal lines in which the transformer is inserted can be realized.

  • Patent number: 6587905
    Abstract: A high performance integrated circuit (IC) with independent read and write data busses enables full simultaneous read and write data transfers between devices coupled to the buses. Multiple master and multiple slave devices communicate using the resources of a bus controller and a bus arbiter. Having separate read and write data busses with separate and independent arbitration allows reads and writes from different devices to occur simultaneously. Many high performance IC, like systems on a chip (SOC), have many different functional units communicating with a central processing unit (CPU). Many such CPUs have architectures that may cause in certain applications an unbalance between read and write traffic on the independent busses. Master and slave devices contain auxiliary internal read and write data buses multiplexed such that read or write data may be interchanged.

  • Patent number: 6564279
    Abstract: A computer system (10) includes a plurality of hot-plug sockets (30-33), each of which can be selectively uncoupled from a bus (59) during normal system operation, in order to facilitate insertion or removal of module (36). A clock signal (PCLK) is generated at one of two different frequencies, and at system power-up a clock arbitration circuit (47) is responsive to modules which are present for specifying a speed of the clock signal. A hot-plug controller circuit (18) can selectively uncouple one of the hot-plug sockets from the bus during normal operation to facilitate insertion or removal of a module, and also facilitates a determination of whether clock speed requirements of an inserted module are compatible with the current clock speed. The selected socket is recoupled to the bus only if the inserted module is compatible with the current clock speed.

  • Patent number: 6557063
    Abstract: A system is described in which the Master can stop its clock and go into a low-power state (for power conservation reasons) at arbitrary times. Before going into the stopped-clock or low-power mode, the Master checks that the serial bus is idle (defined as both Clock and Data lines being “High”). A latch circuit is provided which is active when them aster is in low-power mode. The latch circuit watches for the very first negative-going clock pulse (from the slave), and its configuration is such that when latched, it holds the clock line low. Holding the clock line low prompts the slave to discontinue efforts to send the data. Stated differently, the slave will not conclude that it had successfully sent its data, and this prompts the slave to retain a copy of its data for later resending.
