摘要:
In one embodiment, the present invention includes a method for determining from a data block in a buffer a number of first operands in a first portion of the buffer and a number of second operands in a second portion of the buffer. Based on these numbers, a cyclic redundancy checksum (CRC) operation may be iteratively performed on the first and second operands to obtain a checksum result. The first and second operands are of a different length, and the checksum operation may be executed using processor instructions corresponding to the different lengths. Other embodiments are described and claimed.

Techniques are described herein that may be used to instruct a network component to determine an integrity validation value over information as well as when to include the determined integrity validation value in a network protocol unit to be transmitted. For example, in some implementations, the network component may generate a cyclical redundancy checking (CRC) value. The value may be determined by the network component across multiple segments of information and independent of the utilized protocol.

Techniques are described that can be used by a message engine to notify a core or hardware thread of activity. For example, an inter-processor interrupt can be used to notify the core or hardware thread. The message engine may generate notifications in response to one or more message received from a transmitting message engine. Message engines may communicate without sharing memory space.

A first logic offloads some network protocol unit formation tasks to a second logic. The first logic may request that data be transmitted using a Direct Data Placement (DDP) compatible network protocol unit. The first logic may provide the data as well as other information relevant to forming the DDP compatible network protocol unit. The second logic may form portions of the DDP compatible network protocol unit using the data and the provided information.

In one embodiment, the present invention includes a method for receiving incoming data in a processor and performing a checksum operation on the incoming data in the processor pursuant to a user-level instruction for the checksum operation. For example, a cyclic redundancy checksum may be computed in the processor itself responsive to the user-level instruction. Other embodiments are described and claimed.

A network protocol unit interface is described that uses a message engine to transfer contents of received network protocol units in message segments to a destination message engine. The network protocol unit interface uses a message engine to receive messages whose content is to be transmitted in network protocol units. A message engine transmits message segments to a destination message engine without the message engine transmitter and receiver sharing memory space. In addition, the transmitter message engine can transmit message segments to a receiver message engine by use of a virtual address associated with the receiver message and a queue identifier, as opposed to a memory address.

Techniques are described herein that are capable to perform a retrieval of content from a destination buffer prior to completion of determining an integrity validation value on content of a source buffer. In some cases, if an integrity checking operation on content of the source buffer is successful, the content of the source buffer is copied to the destination buffer. The retrieved content may be written into a cache accessible to one or more processors.
