Third and fourth transistors, coupled to the first and second transistors respectively, each conduct a first current in response to a first reference voltage being applied to a gate of each transistor. A fifth transistor is coupled to the first and second transistors and has a gate to which a second reference voltage is applied to maintain a sum of currents conducted by the first and second transistors equal to a second current. A reference generation circuit is coupled to the third, fourth and fifth transistors and is configured to generate the first and second reference voltages having magnitudes which set the second current equal to twice the first current. A first current difference amplifier has an input coupled to the first and third transistors and is configured to generate one of a first, second and third output voltage levels in response to a sourcing, zero or sinking current, respectively, being received at its input.

    Abstract: The present disclosure discloses a method of complete mutual access of multiple-processors. The method comprises: a separate boot memory and a separate address mapping module are allocated for each processor; the processors perform the mutual access in the multiple-processors through the address mapping module after the processors are booted. The present disclosure also discloses a system for enabling complete mutual access of the multiple-processors. The method and the system creates the advantage of allowing complete mutual access of the multiple-processors, thereby sharing address space in the multiple-processors, sharing the peripheral controller and memory, improving expansibility and performance of the system.

    Abstract: A controller receives an M-bit input and generates, in response, an S-bit upper range binary data feeding S-bit high range DAC and an R-bit lower range data feeding an R-bit low range DAC. The controller detects transition points in the M-bit input and in response, adds a transition data to the S-bit data equal to at least one least significant bit of the S-bit data and subtracts a value from the R-bit data equal to the transition data. The transition points and the transition data are detected and added at points avoiding such transitions at a full scale value of the R-bit data.

    Abstract: A modem that handles interruptions caused by call waiting signals is described. When the modem detects a call waiting signal, the modem alerts the user to the presence of the call waiting signal, and permits the user to answer the incoming call by taking a local phone that is connected to the modem off-hook. When the local phone is taken off-hook, the modem automatically generates a hook-flash signal to switch to the incoming call. When the user places the local phone back on-hook, the modem generates another hook-flash signal to resume (if possible) the modem connection. Additionally, the modem prevents a “fallback”, in which the modem switches from its current protocol to a lower-speed protocol, during a “retrain” process caused by a call waiting event.

    Abstract: Methods and apparatus for dynamically selecting a computer on a local area network to become a server providing shared access to a wide area network, such as the Internet, to all of the computers on the local area network is disclosed. A server may be selected from among any of the computers on the local area network that is currently available (i.e. powered on), and capable of establishing a connection to the wide area network. If the current server shuts down, a new server may be selected and started with only minimal impact on the other computers on the local area network, which are automatically reconfigured to use the new server to route network traffic to the wide area network.
