A computer system, bus interface unit, and method are provided to allocate requests to a shared bus within the computer system. The bus interface unit includes an arbiter which employs a multi-level, round-robin arbitration protocol. Configuration registers are programmed during boot-up of the computer system by assigning a subset of peripheral devices, bus agents, requesters, or bus masters to either a high priority ring or a low priority ring, if two levels of arbitration are used. The status of a low priority device can be elevated to equal priority with a high priority device by assigning the low priority device to a high priority port within the high priority ring if certain circumstances occur. Namely, if data transfers to or from the low priority device are terminated, then the low priority device will be promoted to a high priority device so that it need not wait until after the all high priority device requests have been polled. Instead, the elevated low priority device is placed on the same level of priority as the high priority devices so that its request can be readily serviced and the transaction completed during a data transfer retry operation.

An advanced user interface operates in an integrated operating environment which supports realtime handwriting, graphical and image data. The integrated operating environment is capable of running several application programs on a standard stand-alone processor, such as a personal computer, each in its own display window. A communication window is established in a first window. Image data is imported into it from a second window. And freehand drawing data is added to the first window. The contents of the first window can then be sent to a second processor. In this manner, hand drawn images can be combined with other image data and communicated over a network.

A computer system enables a user to design touch activated keyboards for use on a display surface without writing code. The computer system enables the user to resize and move the keyboard image anywhere on the display to allow the concurrent display of other applications running in an integrated operating environment. Computer system actions can be assigned by the user to each key. An execution unit displays the selected keyboard, determines whether a key has been touched and executes the appropriate action for each key touch.
