A system for testing a processor. The system includes a gold processor and a test access port (TAP). A processor that is a device under test (DUT) is coupled to both the gold processor and the TAP. In the first mode, the TAP provides test signals to both the gold processor and the DUT while they operate in synchronous functional lockstep. In the second mode, the TAP provides signals to the gold processor. In the third mode, the TAP provides test signals to the DUT. A host computer coupled to the interface control unit executes a software application to cause the TAP to drive test signals and to access test output data from the gold processor and the DUT. Test output data accessed from the gold processor may be compared to that accessed from the DUT to determine any differences. The comparison data generated may then be used for further analysis.

An application or terminal emulation program, which is being executed on an information processing system, is represented by the display of a first icon on a display device. If during the execution of the application or terminal emulation program, a virtual display buffer associated with the application program, is updated, a second icon is displayed on the display device to indicate to a user of the system that a change in the status of the program has occurred.

A word processing system is provided having a bidirectional printer with formatting capability. The system includes a word processor having means for outputting a stream of sequential data readable in only one direction. The data comprises blocks of character data representative of the characters to be printed interspersed with blocks of control data representative of the format in which the characters are to be printed; each block of control data has an immediately preceding control block identifier. The bidirectional printer includes means for receiving the stream of sequential data, means for scanning the stream of data and means for inserting a control block identifier at the end of each control block which identifier corresponds to the identifier preceding the control block, whereby the stream of sequential data is made readable in both the forward and reverse directions within the printer.
