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 in an intersystem link (ISL) unit accommodating the transfer of binary coded information between communication busses in a data processing system is disclosed, wherein dedicated locations in a file register are selected at the bus rate in response to binary coded information received from a local communication bus. ISL transactions to be initiated in response to bus cycle requests thereby are identified. ISL transactions are handled in parallel, and memory transfers are segregated from non-memory transfers to avoid unnecessary delays in memory transfers.

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 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.
