    摘要： A multifunction access circuit for use with first and second digital computers each having an address bus for supplying addresses and a data bus for supplying data. The access circuit has an address decoder with inputs for the address bus from the first computer, and an address translator circuit having address inputs for addresses supplied by the address bus of the first computer and outputs for translated addresses to the address bus of the second computer. The address translator circuit also has registers selectable by the address decoder and data inputs to program the registers so selected with data from the data bus from the first computer. Also in the access circuit is a port circuit with registers controlled by the address decoder for entry of address information from the data bus of the first computer and assertion of the address information on the address bus of the second computer. Further, a mode control circuit is connected to the address decoder and connected to the data bus to program the mode control circuit to selectively establish operation of the address translator circuit and of the port circuit. Other access circuits, devices, systems and methods are also described.

    摘要： An access circuit for data swapping between two computers and a computer system including the access circuit. Each computer including an address bus for supplying addresses and a data bus for transferring data. The access circuit includes a register file and two address decoder circuits. The register file has a plurality of storage locations for storing data. The register file has dual data ports capable of simultaneous data transfer via the first data port with a first data storage location and via the second data port with a second, different storage location. Each address decoder is connected to the address bus of a corresponding computer and the register file. The address decoders translate an address received on the address bus to a storage location of the register file. Two handshakes circuits are connected to respective address decoders and digital computers. The first and second address decoders are connected to each other. When the storage location of the first address decoder equals the storage location of the second address decoder, one of the handshake circuits signals the corresponding digital computer a memory waitstate or memory fault. At least one of the decoders is be programmable to position in the address space of the corresponding computer. At least one the address decoders includes an autoincrement circuit advances the accessed storage location within the register file to a next storage location upon each data transfer.

    摘要： A computer graphics system includes a host computer and a graphics processor. The graphics processor includes a control register. When the graphics processor writes to the control register it simultaneously generates a predetermined address on a local address bus and supplies data on a local data bus identical to data to be written into the control register. A shadow register circuit connected to both the host computer and the graphics processor includes a shadow register and first and second address decoders. The first address decoder enables a write from a local data bus into the shadow register upon detection of the predetermined address. The second address decoder enables a read from the shadow register via a host data bus upon detection of the predetermined address on a host address bus. The shadow register optionally includes a message in plurality of bits and a message out plurality of bits, the first and second address decoders enabling message passing between the host computer and the graphics processor. The shadow register circuit optionally includes a host interrupt bit and a buffer circuit. The buffer circuit generates a host interrupt signal to the host computer if either the graphics processor generates a host interrupt signal or the host interrupt bit of the shadow register has a predetermined state.

    摘要： A graphics computer system including a host computer and a graphics processor. The host computer has a host data bus and a host address bus. A first video memory stores color codes corresponding to a display. The first video memory is connected to the host computer permitting it to specify the color codes. A first palette connected to the first video memory has a first look-up table memory for recalling color data words corresponding to color codes received from the first video memory. The first palette is connected to the host computer permitting it to specify the color data words stored in the first look-up table memory. The graphics processor has a local data bus and a local address bus. A second video memory stores color codes corresponding to a display, the graphics processor specifying the color codes stored in the second video memory. A second palette connected to the second video memory has a second look-up table memory. The second palette is connected to the graphics processor permitting it to specify the color data words stored in the second look-up table memory. An interface circuit connects to the host data bus, the host address bus and the second palette. The interface circuit writes data received from the host data bus into the second palette upon detecting predetermined addresses on the host address bus. This causes at least a portion of the second palette to store identical data as stored in corresponding locations of the first palette.
