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： A method used in a multiprocessor computer system for linking extended functions, which are to be called from an application program running on a host processor and executed by a subprocessor, to primitive functions to be executed by the subprocessor. The extended functions may be created independently of the primitive functions, collected in a special partially linked load module, stored, and dynamically linked to other code at run time of the application program.

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 method for handling a cursor during a graphics drawing routine that eliminates the need to insert cursor handling code into graphics function definitions. The method coordinates the placement of the cursor in screen memory with the reading out of the scan lines containing the cursor. During this time, the cursor background is saved in offscreen memory. The cursor is protected by a cursor violation region, and drawing may continue while the cursor is in screen memory so long as the cursor violation region is not infringed, in which case drawing ceases until the cursor is read out of memory. The method prevents the cursor from flickering and maximizes the availability of screen memory to the drawing routine.

摘要： An adapter for modifying graphics software programs at load time. The invention is a process, which may be part of a hardware or firmware configuration used with a computer system, and which scans the program for selected instructions representing routines to be replaced with a substitute routine. If such an instruction is encountered, the instruction is replaced with an interrupt trap. The substitute graphics routine is located at an address stored at the interrupt trap location.

摘要： Apparatus and a method are disclosed for establishing communication between a sending system and a receiving system. Upon initiation of the communication, the sending system sequentially monitors the receiving system for a response from one of a human interface, a non-cooperating system or a cooperating system. If a response from a human interface within the receiving system is received by the sending system, the sending system transmits a message to a human. If a response is not received from a human interface but is received from a non-cooperating system within the receiving system, the sending system transmits a message to an answering machine. If a response is not received from a human interface or a non-cooperating system, but is received from a cooperating system within the receiving system, information is exchanged between the sending system and the cooperating system in an attempt to establish communication.
