Systems and methods for distributing thread instructions in the pipeline of a multi-threading digital processor are disclosed. More particularly, hardware and software are disclosed for successively selecting threads in an ordered sequence for execution in the processor pipeline. If a thread to be selected cannot execute, then a complementary thread is selected for execution.

Systems and methods for adaptively mapping system memory address bits into an instruction tag and an index into the cache are disclosed. More particularly, hardware and software are disclosed for observing collisions that occur for a given mapping of system memory bits into a tag and an index. Based on the observations, an optimal mapping may be determined that minimizes collisions.

摘要:
Method and apparatus for implementing use of a network connection table. In one aspect, searching for network connections includes receiving a packet, and zeroing particular fields of connection information from the packet if a new connection is to be established. The connection information is converted to an address for a location in a direct table using a table access process. The direct table stores patterns and reference information for new and existing connections. The connection information is compared with at least one pattern stored in the direct table at the address to find reference information for the received packet.

A system and method in accordance with the present invention allows for an adapter to be utilized in a server environment that can accommodate both a 10 G and a 1 G source utilizing the same pins. This is accomplished through the use of a high speed serializer/deserializer (high speed serdes) which can accommodate both data sources. The high speed serdes allows for the use of a relatively low reference clock speed on the NIC to provide the proper clocking of the data sources and also allows for different modes to be set to accommodate the different data sources. Finally the system allows for the adapter to use the same pins for multiple data sources.

Apparatus for providing a checksum in a network transmission. In one aspect of the invention, a checksum for a packet to be transmitted on a network is determined by retrieving packet information from a storage device, the packet information to be included in the packet to be transmitted. A blind checksum value is determined based on the retrieved packet information, and the blind checksum value is adjusted to a protocol checksum based on descriptor information describing the structure of the packet. The protocol checksum is inserted in the packet before the packet is transmitted.

A system for reducing latency in a host Ethernet adapter (HEA) includes the following. First, the HEA receives a packet with an internet protocol (IP) header and data in the HEA. The HEA parses a connection identifier from the IP header and accesses a negative cache in the HEA to determine if the connection identifier is not in a memory external to the HEA. The HEA applies a default treatment to the packet if the connection identifier is not in the memory, thereby reducing latency by decreasing access to the memory.

摘要:
A system and method for parsing, filtering, and computing the checksum in a host Ethernet adapter (HEA) that is coupled to a host. The method includes receiving a part of a frame, wherein a plurality of parts of a frame constitute a entire frame. Next, parse the part of a frame before receiving the entire frame. The HEA computes a checksum of the part of a frame. The HEA filters the part of a frame based on a logical, port-specific policy and transmits the checksum to the host.
