    Abstract: A computer system which includes a DMA controller on the local I/O unit which can be programmed by either the host processor or the local processor. Semaphore flags and lock bits are provided to allow determination of control of the local DMA controller and for passing information. Additionally, data alignment and padding circuitry is provided. The circuitry is informed of the logical data arrangement desired or utilized by the host processor or other devices and knows the data arrangement of the local processor. The circuitry properly obtains and realigns the data based on the transfer direction and data arrangement. The circuitry further properly zero pads the data when realignment is such that padding is necessary.

    Abstract: A method and apparatus of assuring uniqueness of identification numbers of bus devices connected to a bus. Each bus device has a current identification number. At each of the bus devices, an identification number is received on a bus and the bus is contended for based on the received identification number. If more than one bus device is detected contending for the bus, the current identification number of one of the bus devices is changed. Each of the bus devices compares the received identification number to the current identification number of the bus device. A bus device provides a match indication, including driving a signal, if the comparison produces a match. Each bus device includes a collision detector for detecting if more than one bus device is driving the signal.

    Abstract: A monitor provides analog conditioning circuitry for supplying a symmetrical high speed analog output signal generated from inverted and non-inverted digital data to imagers for a display of the monitor. The circuitry includes an upper bias amplifier for generating a precision upper DC offset signal. a lower bias amplifier for generating a precision lower DC offset signal, a switch for alternating selection of a precision DC offset signal with each frame, and a summing amplifier for adding the selected precision DC offset signal to a high speed analog signal provided by a digital-to-analog converter. Selection of the precision DC offset signal is controlled by an inversion signal provided to the switch from an inversion bit of a display controller. The digital data inversion is controlled by inversion circuitry within the display controller. The analog conditioning circuitry thus provides a single gain path and also provides low speed signal paths decoupled from a high speed signal path.
