Abstract
New and improved methods and apparatus for transmitting data over a data bus. The invention provides a bus system including an external shared bus, an external bus interface, and a resource bus. The external bus interface can be configured to move data between the external shared bus and the resource bus. The bus system can also include a data processing pipeline coupled to the resource bus. The data processing pipeline can include a plurality of components for processing data. Some of the data processing components can be coupled to the resource bus.
