    摘要: A logic control system is disclosed for verifying the operability of memory and non-memory data and control paths in both local and remote intersystem link (ISL) units electrically interconnecting a local and remote communication bus in a data processing system. The data processing system may include two or more communication busses each pair of which are electrically interconnected by twin ISL units. The control logic architecture accommodates the receipt of a test mode command from a CPU on a local bus to initiate a test mode operation wherein the memory and non-memory data and control paths of both the local and the remote ISL units are excerised while on-line, and binary coded information received from the local bus is passed through the ISL units, onto the remote bus, and returned to a local bus memory resource for verification. No remote bus resources are used or affected, and the remote ISL unit shall ignore any communications received from any other data processing unit on the remote bus. The remote ISL unit is effectively non-existent to other data processing units on the remote bus.

    摘要: A bus interface interrupt arrangement is disclosed which provides separate interrupt controllers for each bus in a multibus computer system where the processor is connected to one of the busses. Interrupt requests decided on each of the busses other than a primary bus to which the processor is connected are input along with interrupts from circuits connected to the primary bus to the interrupt controller for the primary bus. The interrupt request decided by the interrupt controller for the primary bus is connected to an interrupt input of the processor. All interrupt controllers are connected to the primary bus and may be accessed by the processor. When an interrupt from one of the busses other than the primary bus is chosen by the processor, the processor must read the interrupt controllers to determine first what bus, and then identify the circuit that generated the interrupt that has been acknowledged. Using this information circuits in the bus interface interrupt arrangement are operated to pass data and addresses between the primary bus and the chosen bus. These circuits are operated in a manner to pass data between busses having different data path sizes.

    摘要: A logic system is provided for accommodating the exchange of information between two or more communication busses of a data processing system, wherein plural central processing units and plural memory units on independent communication busses may have same logic addresses. Memory and CPU addresses are translated at the bus rate through a multiplicity of flexible address translation ranges to enable a data processing unit on one communication bus to access an apparent contiguous range of addresses encompassing all data processing units on all communication busses.

    摘要: A logic system referred to as an intersystem link unit (ISL) is provided for accommodating the transfer of binary coded information between two or more communication busses in a data processing system, wherein information including memory and non-memory read and write requests, CPU to CPU interrupts, peripheral control units to CPU interrupts may be transferred between plural communication busses each supporting plural data processing units including plural CPUs without substantially affecting the bus rate of the individual communication busses. Binary coded information from a communication bus is acquired asynchronously, and plural bus communications of different types are accommodated in parallel. The ISL units further may be dynamically reconfigured to provide for a reallocation of communication bus resources between communication busses.
