The poor scalability of existing superscalar processors has been of great concern to the computer engineering community. In particular, the critical-path delays of many components in existing implementations grow quadratically with the issue width and the window size. This patent presents a novel way to reimplement these components and reduce their critical-path delay growth. It then describes an entire processor microarchitecture, called the Ultrascalar processor, that has better critical-path delay growth than existing superscalars. Most of our scalable designs are based on a single circuit, a cyclic segmented parallel prefix (cspp). We observe that processor components typically operate on a wrap-around sequence of instructions, computing some associative property of that sequence. For example, to assign an ALU to the oldest requesting instruction, each instruction in the instruction sequence must be told whether any preceding instructions are requesting an ALU. Similarly, to read an argument register, an instruction must somehow communicate with the most recent preceding instruction that wrote that register. A cspp circuit can implement such functions by computing for each instruction within a wrap-around instruction sequence the accumulative result of applying some associative operator to all the preceding instructions. A cspp circuit has a critical path gate delay logarithmic in the length of the instruction sequence. Depending on its associative operation and its layout, a cspp circuit can have a critical path wire delay sublinear in the length of the instruction sequence.

A system and method for assigning certificates and reducing the size of the certificate revocation lists in a PKI based architecture for a vehicle wireless communications system that includes separating a country, or other area, into geographic regions and assigning region-specific certificates to the vehicles. Therefore, a vehicle need only process certificates and certificate revocation lists for the particular region that it is traveling in. Vehicles can be assigned multiple certificates corresponding to more than one region in the vehicles vicinity as advance preparation for possible travel or transmission into nearby regions. Further, the expiration time of certificates assigned to vehicles corresponding to a given geographic region can be tailored to be inversely proportional to the distance from a registered home region of the vehicle. A scalable design for a back-end certifying authority with region-based certificates can also be provided.

The invention discloses a plug-in mechanism-based virtual machine migration method. According to the plug-in mechanism-based virtual machine migration method, a source virtual machine management platform and a target virtual machine management platform are provided, and a migration agent module, a driving module and an import guide module are designed.

The invention discloses an ultra-long distance distribution type optical fiber sensor and a method for measuring temperature and vibration signals. The ultra-long distance distribution type optical fiber sensor adopts a multi-stage relay amplifier, and a high-power pulse light source enters a detecting optical fiber stage by stage through proportional allocation of a plurality of optical fiber couplers and transmission of transmission fibers, and re-amplifies the pulse of the detecting light at a specified length, thereby improving the signal to noise ratio of the system in terms of 'source', being capable of avoiding non-linear scattering caused by overrun light which enters a detecting optical cable directly on one hand, and being capable of reducing higher energy loss caused by continuous light transmission on the other hand. The ultra-long distance distribution type optical fiber sensor adopts the staged design, thereby greatly reducing the requirement on receiving sensitive and dynamic range of a receiving circuit. In addition, the ultra-long distance distribution type optical fiber sensor adopts the expandable design, thereby being capable of conveniently realizing short-distance detection, long-distance detection and ultra-long distance detection in sequence.

A register file apparatus and method incorporating read-after-write blocking using detection cells provides improved read access times in high performance register files. One or more detection cells identical to the register file cells and located in the register file array are used to control the read operation in the register file by configuring the detection cells to either alternate value at each write or change to a particular value after a write and then detecting when the write has completed by detecting the state change of an active detection cell. The state change detection can be used to delay the leading edge of a read strobe or may be used in the access control logic to delay generation of a next read strobe. The register file thus provides a scalable design that does not have to be tuned for each application and that tracks over voltage and clock skew variation.
