    摘要: Circuitry for drawing lines includes a video memory for storing pixel data and circuitry for generating a sequence of addresses defining a line of pixels in the video memory. A first memory stores a sequence of pattern units corresponding to the generated sequence of addresses. A second memory stores a value indicating a current pattern unit. Writing circuitry writes to the video memory at a generated address responsive to a current pattern unit. A third memory stores a control value which is accessed by update circuitry for updating the second memory to indicate the next pattern unit. The update circuitry may selectively update the second memory to the sequential pattern unit or reset the second memory to a predetermined pattern unit.

    摘要: 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.

    摘要: 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.
