摘要： A method for enabling 8-bit data word access over a protocol limited to 16-bit data word access is provided. Data may be encapsulated within the lowest 19 bits of a 20-bit number. If it is ascertained that an 8-bit data word is to be used in a system supporting only 16-bit data word access, a byte-enable indicator may be provided within a most significant bit of the 20-bit number while also allocating an 8-bit data region for transfer of the 8-bit data word. The 20-bit number may then be transcoded into a 12-digit ternary number, wherein a residual numerical region is defined as a number space by which a first numerical region defined for the 12-digit ternary number exceeds a second numerical region defined by the lowest 19 bits of the 20-bit number.

摘要： To accommodate multiple masters over bus architectures supporting a single master device, a mechanism is provided for an inactive master device to trigger an IRQ signal over a shared, single line IRQ bus. A current master then polls the other inactive master devices over a shared data bus to ascertain which inactive master device is asserting the IRQ signal. Upon identifying the asserting inactive master device, the current master device grants control of the data bus to the new master device, thereby making the inactive master the new active master device.

摘要： A configuration for data transfer with a parallel bus system including an address bus, a data bus and a control bus and with several units interfacing with them. A first control line is used to send an acknowledge signal with which one or more units addressed by a first unit acknowledge accesses in access cycles. A second control line is used to detect addressing errors and accesses to non-existing units and to carry a signal ready control signal to the first unit from the others indicating whether one of the interfaced units was addressed. To do so, the signal ready control signal has dominant and recessive states. During an access cycle, only addressed units generate a dominant state. The control signal is also used for synchronous multipoint access. The invention can be used in bus systems.

摘要： Each user of an intercommunication bus is associated with a distinct channel of an arbitration bus and maintains a priority record indicating its current priority status against each other user. During a contention interval each user then seeking to use the intercommunication bus bids for use of it by transmitting a bus request signal and makes an analysis of the signals to ascertain if it has dominating priority for initiating a transaction on the bus, and access is granted accordingly. During the use-signal interval a user then using the intercommunication bus transmits an in-use signal used to up-date priority records with the effect of giving the last using user lowest priority. For transactions which require a response from a user other than the one initiating the transaction, a second round of bidding is conducted to determine whether any user is qualified to respond and if so which will be enabled to do so. When the response bidding shows no bidders the system immediately initiates bidding for a new transaction.

摘要： In a data processing system which uses a common bus for communication of address and data information among a plurality of system components, a bus timing technique uses a clock signal having a transfer time period which comprises a plurality of subperiods which requires address transfer to take place during a first selected group of subperiods and data to be transferred during a second selected group of subperiods with idle subperiods in between. A first control signal is generated by the data receiving or data supplying unit in order to inhibit access to the bus until such transfer is completed and a second control signal can be provided to lock-in bus access by such unit if desired for more than one transfer period. Appropriate priority is arranged for bus access among selected system components whether the common bus system has a single bus for use with a single port memory or a dual bus for use with a dual port memory.

摘要： In a data processing system, a bus is provided for the transfer of information between units coupled to the bus. The units are coupled in a priority arrangement which is distributed thereby providing priority logic in each of the units and allowing bus transfer cycles to be generated in an asynchronous manner. Priority is normally granted on the basis of physical position on the bus, highest priority being given to the first unit on the bus and lowest priority being given to the last unit on the bus. Each of the units includes priority logic which includes logic elements for requesting a bus cycle, such request being granted if no other higher priority unit has also requested a bus cycle. The request for and an indication of the grant of the bus cycle are stored in each unit so requesting and being granted the bus cycle respectively, only one such unit being capable of having the grant of a bus cycle at any given time, whereas any number of such units may have its request pending at any particular time. A modification to the priority logic allows a lowest priority unit to be physically positioned at other than the last unit position on the common bus.

摘要： A digital data processing system including an interconnection for the various elements that constitute the system. Each element that connects to the interconnection is called a nexus. For one element to communicate with another element, the one element, as a commanding nexus, seeks control of the interconnection and then transmits a command and address of a storage location in the other element when it receives control of the interconnection. Control is then relinquished unless the one element is to send data to the other element whereupon the data is sent immediately. If data is to be retrieved, the other element retrieves the data, requests control of the interconnection and, when it receives control, transmits the data onto the interconnection with an identification of the one element. The one element then retrieves the data from the interconnection when it recognizes its own identification. If the other element is a memory element, it also contains storage file for storing commands and data if it already is operating in response to another element's command.

摘要： A input/output method is disclosed for performing communications in a virtual machine (VM) environment between a host operating system (OS) and a guest OS. The input/output method includes performing request polling (RP) on an input/output event generated by a guest OS which is driven by a virtual machine (VM), sending an input/output request to a host OS, on which the VM runs. The input/output method further includes performing response waiting polling (RWP) on an input/output completion message generated by the host OS when the input/output event is detected through the RP, and sending an input/output response to the guest OS when the input/output completion message is detected through the RWP. In the method, the RP and the RWP are performed by multiple threads executed on the VM.
