摘要： A graphics display apparatus with a combined bit buffer and character graphics store includes a coded display buffer containing pointers to the store. The store is constituted by odd and even memories used to derive bit patterns for odd and even character cell columns on the display and is partitioned into a font area and a bit buffer area. In a first mode of operation, compatible with existing programmed symbol arrangements, pointers in the coded display buffer in conjunction with odd/even select signals and slice signals derive the bit patterns for each raster scan line of the display. In a second mode of operation, a graphic image to be displayed is stored as a bit map in the bit buffer area: the required bit pattern is derived using slice and odd/even select signals in conjunction with pointers stored in the coded display buffer.

摘要： An interactive data retrieval apparatus in which a data base store is searched by content using search keys entered by an operator. Dedicated hardware includes a plurality of search modules and apparatus for clocking the byte-wide data stream read from the data store through successive search modules. In each module, the data is compared with an entered search key. When a match is found between the data stream and the search keys, the data record is displayed to the operator. The apparatus can detect near matches to allow for misspellings etc. In one embodiment of the search module, a plurality of comparison cells perform byte-equality operations on search key data stored in a search key register and the data stream. In a second embodiment, an associative store contains the n-character search key, the associative store being addressed by each character in the data stream as it is clocked past its data port. n shift registers are connected to the outputs of the associative store and are shifted in synchronism with the data stream.

摘要： Provided is a method and a system for computer network monitoring, implemented in a network in which processes communicate using message queuing. Each node of the network has a network management program installed thereon which includes two independent components: a Point Of Control (POC) program for initiating network tests by injecting a test message into the network and for receiving responses from all the nodes of the network; and a Network Test Program (NTP) for sending a reply message to the single POC for a particular test when the NTP receives test messages within that test, and for propagating the test by forwarding a message to all of the current node's adjacent nodes. Test results are analyzed at the POC for display to the network administrator. Injected test messages propagate throughout the network in a self-exploring manner, exploiting the parallelism of the network. The individual nodes are not required to know the network topology other than to know their nearest neighbor nodes.

摘要： A data processing system displays options for selection by a user as a hierarchical tree form diagram. When a user indicates his first selected option to the data processing system it calculates what further selections are and are not available as a result of the selected option. It then modifies the display to show the options which are available for selection and those which are not. A selection list is stored and updated by the data processing system and the options input by the user are executed when the selection list is complete.

摘要： A graphics display apparatus employing a raster scanned cathode ray tube uses a refresh buffer constituted by a coded alphanumeric buffer and an associated character generator for displaying alphanumeric characters and other symbols and an all-points-addressable buffer for displaying graphics. Serialized data from the two buffers are mixed in a mixer under control of at least one control bit (attribute) stored in the coded buffer to provide a composite pel-representing bit stream supplied to the cathode ray tube.
