    摘要: Interface circuitry is provided to control the flow of data transmitted over a high-speed serial link. The interface circuitry may receive data over a high-speed serial link and store the received data in a receive buffer. The receive buffer may be connected to an additional buffer in an application layer module. The application layer module may produce credits based on the processing capacity of the additional buffer and send those credits to the interface circuitry. The interface circuitry may then send these credits over the high speed link.

    摘要: An integrated circuit with a high-speed debug access port includes interface circuitry and a dedicated debug port in the interface circuitry. The interface circuitry includes a function circuit block that is used to receive a data packet from external circuitry coupled to the integrated circuit. The dedicated debug port is coupled to the function circuit block and is used to transmit the received data packet to debug circuitry on the integrated circuit. The interface circuitry may include a peripheral component interconnect express (PCIe) interface circuit.

    摘要: One embodiment relates to an integrated circuit with a modular direct memory access system. A read data mover receives data obtained from a source address, and a write data mover for sends the data to a destination address. A descriptor controller provides the source address to the read data mover and the destination address to the write data mover. Another embodiment relates to a method of providing direct memory access. Another embodiment relates to a system which provides direct memory access. Other embodiments and features are also disclosed.
