20090089578 | DIGEST GENERATION FROM INSTRUCTION OP-CODES - In general, in one aspect, a computer-implemented method includes determining a digest value based on hash operations on values of, at least, a set op-codes of multiple instructions of a program during execution of the program by a processor. | 04-02-2009 |
20090316711 | PACKET SWITCHING - In an embodiment, an apparatus is provided that may include an integrated circuit including switch circuitry to determine, at least in part, an action to be executed involving a packet. This determination may be based, at least in part, upon flow information determined, at least in part, from the packet, and packet processing policy information. The circuitry may examine the policy information to determine whether a previously-established packet processing policy has been established that corresponds, at least in part, to the flow information. If the circuitry determines, at least in part, that the policy has not been established and the packet is a first packet in a flow corresponding at least in part to the flow information, the switch circuitry may request that at least one switch control program module establish, at least in part, a new packet processing policy corresponding, at least in part, to the flow information. | 12-24-2009 |
20110145679 | Validating Data Using Processor Instructions - 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. | 06-16-2011 |
20110153877 | METHOD AND APPARATUS TO EXCHANGE DATA VIA AN INTERMEDIARY TRANSLATION AND QUEUE MANAGER - Techniques for performing direct memory access (“DMA”) in an architecture wherein an interconnect separates I/O means from a DMA engine for handling DMA requests of the I/O means. In an embodiment, the I/O means sends via the interconnect a DMA request including an address-non-specific identifier of a queue which is a target of the DMA request. In another embodiment, the DMA engine determines an address-specific identifier of a location in the queue in response to the sending of the DMA request. | 06-23-2011 |

20140082334 | Encoding to Increase Instruction Set Density - A conventional instruction set architecture such, as the x86 instruction set architecture, may be reencoded to reduce the amount of memory used by the instructions. This may be particularly useful in applications that are memory sized limited, as is the case with microcontrollers. With a reencoded instruction set that is more dense, more functions can be implemented or a smaller memory size may be used. The encoded instructions are then naturally decoded at run time in the predecoder and decoder of the core pipeline. | 03-20-2014 |
