摘要： A Island-Based Network Flow Processor (IBNFP) includes a memory and a processor located on a first island, a Direct Memory Access (DMA) controller located on a second island, and an Interlaken Look-Aside (ILA) interface circuit and an interface circuit located on a third island. A search key data set including multiple search keys is stored in the memory. A descriptor is generated by the processor and is sent to the DMA controller, which generates a search key data request, receives the search key data set, and selects a single search key. The ILA interface circuit receives the search key, generates and ILA packet including the search key that is sent to an external transactional memory device that generates a result data value. The DMA controller receives the result data value via the ILA interface circuit, writes the result data value to the memory, and sends a DMA completion notification.

摘要： An efficient search key processing method includes writing a first and a second search key data set to a memory, where the search key data sets are written to memory on a word by word basis. Each of the first and second search key data sets includes a header indicating a common lookup operation to be performed and a string of search keys. The header is immediately followed in memory by a search key. The search keys are located contiguously in the memory. At least one word contains search keys from the first and second search key data sets. The memory is read word by word. A first plurality of lookup command messages are sent based on the search keys included in the first search key data set. A second plurality of lookup command messages are sent based on the search keys included in the second search key data set.

摘要： A method of dynamically allocating buffers involves receiving a packet onto an ingress circuit. The ingress circuit includes a memory that stores a free buffer list, and an allocated buffer list. Packet data of the packet is stored into a buffer. The buffer is associated with a buffer identification (ID). The buffer ID is moved from the free buffer list to the allocated buffer list once the packet data is stored in the buffer. The buffer ID is used to read the packet data from the buffer and into an egress circuit and is stored in a de-allocation buffer list in the egress circuit. A send buffer IDs command is received from a processor onto the egress circuit and instructs the egress circuit to send the buffer ID to the ingress circuit such that the buffer ID is pushed onto the free buffer list.

摘要： A device includes a Standard Bus Interface Circuit (SBIC), a memory interface circuit, a Direct Memory Access (DMA) controller, and an Interlaken Look-Aside (ILA) interface circuit. A search key data set including multiple search keys is received via the SBIC and is written to an external memory via the memory interface circuit. The DMA controller receives a descriptor via the SBIC, generates a search key data request, receives the search key data set, and selects a single search key from the set. The ILA interface circuit receives the search key from the DMA controller, generates and ILA packet including the search key, and sends the ILA packet to an external transactional memory device that generates a result data value. The DMA controller receives the result data value via the ILA interface circuit, writes the result data value to the external memory, and sends a DMA completion notification.

摘要： A multi-processor includes a shared memory that stores a search key data set including multiple search keys, a processor, a Direct Memory Access (DMA) controller, and an Interlaken Look-Aside (ILA) interface circuit. The processor generates a descriptor that is sent to the DMA controller causing the DMA controller to read the search key data set. The DMA controller selects a single search key from the set and generates a lookup command message that is communicated to the ILA interface circuit. The ILA interface circuit generates an ILA packet that includes the single search key and sends the ILA packet to an external transactional memory device that generates a result data value. The result data value is communicated back to the DMA controller via the ILA interface circuit. The DMA controller stores the result data value in the shared memory and notifies the processor that the DMA process has completed.
