    摘要: An apparatus and method for performing a shuffle operation on packed data using computer-implemented steps is described. In one embodiment, a first packed data operand having at least two data elements is accessed. A second packed data operand having at least two data elements is accessed. One of the data elements in the first packed data operand is shuffled into a lower destination field of a destination register, and one of the data elements in the second packed data operand is shuffled into an upper destination field of the destination register.

    摘要: Multiple initialization techniques for system and component in a point-to-point architecture are discussed. Consequently, the techniques allow for flexible system/socket layer parameters to be tailored to the needs of the platform, such as, desktop, mobile, small server, large server, etc., as well as the component types such as IA32/IPF processors, memory controllers, IO Hubs, etc. Furthermore, the techniques facilitate powering up with the correct set of POC values, hence, it avoids multiple warm resets and improves boot time. In one embodiment, registers to hold new values, such as, Configuration Values Driven during Reset (CVDR), and Configuration Values Captured during Reset (CVCR) may be eliminated.For example, the POC values could be from the following: Platform Input Clock to Core Clock Ratio, Enable/disable LT, Configurable Restart, Burn In Initialization Mode, Disable Hyper Threading, System BSP Socket Indication, and Platform Topology Index.

    摘要: An Advanced Encryption Standard (AES) key generation assist instruction is provided. The AES key generation assist instruction assists in generating round keys used to perform AES encryption and decryption operations. The AES key generation instruction operates independent of the size of the cipher key and performs key generation operations in parallel on four 32-bit words thereby increasing the speed at which the round keys are generated. This instruction is easy to use in software. Hardware implementation of this instruction removes potential threats of software (cache access based) side channel attacks on this part of the AES algorithm.

    摘要: In one embodiment, a buffer is presented. The buffer comprises a type designator to designate that the buffer is a streaming read buffer, and a plurality of use designators to indicate whether data within the buffer has been used. The data within the buffer is an uncacheable memory type, such as Uncacheable Speculative Write Combining (USWC) memory. Furthermore, in some embodiments, the buffer is allocated upon execution of a streaming read buffer instruction. In other embodiments, the data within the buffer can only be used once and cannot be cached elsewhere in the processor.
