In a first aspect, a first method is provided for allocating memory bandwidth. The first method includes the steps of (1) assigning a fixed priority of access to the memory bandwidth to one or more direct memory access (DMA) machines; and (2) assigning a programmable priority of access to the memory bandwidth to a processing unit. The programmable priority of the processing unit allows priority allocation between the one or more DMA machines and the processing unit to be adjusted dynamically. Numerous other aspects are provided.

System and method for allocating memory allocation bandwidth by assigning fixed priority of access to DMA machines and programmable priority to processing unit

A method and system for easily and automatically determining the extent of test coverage for a design-under-test (DUT). Incremental test coverage information is gathered from the application of test cases to the DUT, and cumulative test coverage information is maintained. The incremental test coverage and cumulative test coverage information are fed into a correlation process, which correlates valid bus transactions automatically generated from a configuration file describing the DUT with the incremental and cumulative test coverage information. The correlation process determines which valid bus transactions have or have not been applied in testing the DUT.
