    摘要: Various apparatuses, methods and systems for specifying memory transaction sizes on a PCI bus are disclosed herein. For example, some embodiments of the present invention provide apparatuses for transferring data including a PCI bus, a memory map for memory transactions performed on the PCI bus, and at least one set of control registers adapted to establish at least one window within the memory map. The set of control registers contains an address range for the at least one window within the memory map and a burst transfer size for memory transactions taking place on the PCI bus that are addressed within the address range.

    摘要: A method of aggregating events in a PCIe (Peripheral Component Interconnect Express) multifunction device minimizes reported error messages, where several functions share a common PCIe interface logic. A predetermined number of function entities with logical gates, connected in daisy chain configuration, process incoming information, and a decision is made whether each function entity will generate a blocking control or a pass-through control. The error messages are aggregated across the function entities in a single clock cycle with the help of an error controller. The functions can be from IEEE 1394 interface, graphics display controller, sound card, PCIe switch, or PCIe to PCI bridge connection. Each function preferably has a different configuration and security level setting for error reporting and messaging. There may be a plurality of parallel daisy chains, and the PCIe device may include three layers namely, a physical layer, data link layer and transaction protocol layer (for error logging, reporting).
