  • Interrupt handling system for message transfers in network having mixed hardware and software emulated modules
    Patent number: 5999969
    Abstract: A system whereby a receiving module, in a mixed network of hardware and software-emulated modules, requires an Interrupt before it can use a Get Message OP to access a message from a message queue and which also provides a Fast Empty of messages in a message queue by eliminating the need for an Interrupt before each succeeding message access.

  • Control method for message communication in network supporting software emulated modules and hardware implemented modules
    Patent number: 5983266
    Abstract: A method for message transfers between digital modules in a network where some modules are hardware implemented and some modules are emulated in software. An Auxiliary Message Arbitrator Unit utilizes Main Memory storage for messages destined for receiving modules. Algorithmic sequencing means maintains chronological transfer operations of messages and uses hard and soft Interrupt signal queues to inform respective hard and soft modules of pending messages for them to retrieve.
