Site-consolidated disaster-recovery with synchronous-to-asynchronous traffic conversion
A disaster-recovery system contains a networked array of synchronous-to-asynchronous converter (SATC) modules that connect source databases to target backup databases. During backup, the system replicates each source-database transaction through a chain of these SATCs to a corresponding target, storing a local copy of the transaction on each SATC along the way. Each transaction's path between its source-target pair is identified by a set of tracking entries, where each entry identifies one SATC in the path. Before initiating a recovery operation, the system regenerates the tracking entries in order to reconstruct paths to source databases. The system then synchronously searches SATCs along each path for local copies of lost transactions that had not time to be fully replicated before the occurrence of a catastrophic failure. The full-blown recovery is started only after all lost transactions have been properly replicated to target databases. |

Effective gear-shifting by queue based implementation
In a conventional system with a UFS storage device connected to a UFS host over one or more lanes, the lanes can support different transmission speeds, referred to as gears. The UFS host shifts lanes and gears based on the type of request it receives. When the requests arrive in random order of gear requirements, the frequent shifting of the lanes and gears causes significant power consumption. To address this issue, it is proposed to implement a queue-based shifting in which arriving requests may be queued based on their gear requirements. When a queue is selected, multiple requests in the selected queue, which are all of same or similar gear requirement, can be served. This can reduce the frequency of gear shifting, and hence reduce power consumption. |

Using return address predictor to speed up control stack return address verification
Overhead associated with verifying function return addresses to protect against security exploits is reduced by taking advantage of branch prediction mechanisms for predicting return addresses. More specifically, returning from a function includes popping a return address from a data stack. Well-known security exploits overwrite the return address on the data stack to hijack control flow. In some processors, a separate data structure referred to as a control stack is used to verify the data stack. When a return instruction is executed, the processor issues an exception if the return addresses on the control stack and the data stack are not identical. This overhead can be avoided by taking advantage of the return address stack, which is a data structure used by the branch predictor to predict return addresses. In most situations, if this prediction is correct, the above check does not need to occur, thus reducing the associated overhead. |

Waveguide formation using CMOS fabrication techniques
Conventional approaches to integrating waveguides within standard electronic processes typically involve using a dielectric layer, such as polysilicon, single-crystalline silicon, or silicon nitride, within the in-foundry process or depositing and patterning a dielectric layer in the backend as a post-foundry process. In the present approach, the back-end of the silicon handle is etched away after in-foundry processing to expose voids or trenches defined using standard in-foundry processing (e.g., complementary metal-oxide-semiconductor (CMOS) processing). Depositing dielectric material into a void or trench yields an optical waveguide integrated within the front-end of the wafer. For example, a shallow trench isolation (STI) layer formed in-foundry may serve as a high-resolution patterning waveguide template in a damascene process within the front end of a die or wafer. Filling the trench with a high-index dielectric material yields a waveguide that can guide visible and/or infrared light, depending on the waveguide's dimensions and refractive index contrast. |

A method and apparatus are provided for positron emission imaging to correct a recorded energy of a detected gamma ray, when the gamma ray is scattered during detection.
