Abstract: The grouping of windows based on user-defined contexts is disclosed. A computer-implemented method of grouping windows based on user-defined contexts in accordance with an embodiment includes: assigning a user-defined context to a plurality of elements in an environment; grouping the plurality of elements into at least one group based on the user-defined context assigned to each of the plurality of elements; and displaying a context window tab corresponding to each group of elements.

Abstract: A connection is provided between logical macros to allow prioritization of operations in accordance with an arbitration scheme that distinguishes between operations based on such factors as priority or size of transaction. The invention allows connection of logical macros and prioritizes the appropriate operation for the resources available to optimize data throughput to optimize the utilization of multiple buses. A first arbiter manages data transmissions over a first communication bus. Arriving short or high-priority messages are transmitted over a second communication bus managed by a second arbiter, but only if the target logical macro is not the same as currently targeted by the first arbiter.
