摘要:
An apparatus comprising a plurality of IO queues and a logic circuit. The plurality of IO queues each may be configured to receive a respective IO request and present the IO request in response to a trigger signal. The logic circuit may be configured to (a) (i) receive one or more of the IO requests and (ii) serially coalesce the IO requests in response to a respective device identification (ID) of the IO requests, and (iii) present one or more of the coalesced IO requests as one or more respective context queue requests in response to the trigger signal and (b) generate the trigger signal when a current queue count is equal to a maximum queue depth.

Circuits and associated methods for testing internal operation of an application integrated circuit. Features and aspects hereof add configurable test interrupt circuits to an application circuit design to permit dynamic, configurable interrupt generation from an integrated circuit based on conditions determined from monitoring of internal signals of the application circuit. The internal signals that may be tested and used to generate test interrupts are those not exposed to the external processor interface of the integrated circuit and thus may be configured to interrupt based on any internal state of the application specific functional circuits of the integrated circuit.
摘要:
In a computer system, a bus adapter processes bus operation information structures for performing bus operations by automatically starting processing each bus operation information structure after completing processing the previous bus operation information structure. A processor forms the bus operation information structures and sets control over each bus operation information structure to a sequencer for processing. When a next bus operation information structure is ready for processing after completing processing the previous bus operation information structure, the sequencer checks whether it has control over the next bus operation information structure, and if so, begins processing the next bus operation information structure without being instructed to do so by the processor.
摘要:
A message-based I/O architecture comprising a list describing one or more source buffers and a message header. The list may be segmented in multiple memory locations. The message header may be configured to (i) indicate whether the list is segmented and (ii) provide information for linking the list when the list is segmented.
