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).

摘要： A PCI bus time-based weighted round robin arbiter has a phase table divided into a plurality of phases. Each of the phases is assigned to one of the ports on the PCI bus. An arbiter state machine is coupled to the phase table and looks at the port assignment for the next plurality of phases, for example, 3 phases. If the arbiter determines that the next plurality of phases is assigned to a single port, that port is selected as the next bus master.

摘要： Methods and systems are provided for receiving and assembling serial data into parallel arrangements referred to as data slices. A plurality of data slices define a data line. Data slices common to a data line are written across like addresses of memory logically partitioned as memory slots. Respective memory slots are selected for data write operations in a successively advancing manner. As a result, a just-written data slice is immediately available for reading on the next clock cycle. Also, respective data slices can be simultaneously written to and read from the same or different memory slots on a particular clock cycle. Fast serial data communication between peripheral devices and other computer-related entities is performed accordingly.
