Embodiments of the specification disclose a transaction execution method, apparatus, and device applicable in a client terminal and a server. The transaction execution method includes: scanning an offline object and a corresponding identification code thereof, the identification code comprising positioning assistance information of the offline object; triggering a recognition process for the offline object and the identification code; and executing a transaction with respect to the offline object based on a result of the recognition process.

Service execution method, apparatus, and device for use in client terminal and server

The present application discloses active/inactive state detection methods, where the method is performed by a monitoring and detecting system, and includes the following: monitoring a distance between an object and a target object within a distance detection range; when the distance between the object and the target object satisfies a first predetermined condition, sending a first instruction to an image acquisition system corresponding to the distance detection range, so as to activate the image acquisition system to obtain an image in an image acquisition area of the image acquisition system; and determining a state of the target object based on a recognition result obtained by performing object recognition on the image in the image acquisition area, where the state of the target object includes an active state and/or an inactive state. In the implementations of the present application, whether a predetermined object is active and/or inactive can be accurately determined, system power consumption can be effectively reduced, and application needs can be satisfied.

Active/inactive state detection method and apparatus

A settlement apparatus includes shielding walls, a shielding door configured to, when closed, enclose an electromagnetic shielding space with the shielding walls for isolating signals inside and outside the electromagnetic shielding space, a reader configured to acquire data in an electronic tag in the electromagnetic shielding space, and a controller configured to control opening or closing of the shielding door, control the reader to acquire data, and settle according to the data.

Settlement method and apparatus

A control unit of the article processing terminal controls a radio frequency identification (RFID) reader of the article processing terminal to periodically scan a plurality of short-range articles. In response to a status change of an article of the plurality of short-range articles, the control unit receives an article identifier of the article from the RFID reader. The control unit controls a low-power wide-area network (LPWAN) module of the article processing terminal to send an article change message to a LPWAN gateway, where the article change message includes the article identifier and an address of an application server, and where the LPWAN gateway instructs, based on the article change message and the address, the application server to perform a next processing step on the article identified by the article identifier.

Article processing method, terminal, system and LPWAN gateway

Detecting data dependencies of instructions associated with threads in a simultaneous multithreading (SMT) scheme is disclosed, including: dividing a plurality of comparators of an SMT-enabled device into groups of comparators corresponding to respective ones of threads associated with the SMT-enabled device; simultaneously distributing a first set of instructions associated with a first thread of the plurality of threads to a corresponding first group of comparators from the plurality of groups of comparators and distributing a second set of instructions associated with a second thread of the plurality of threads to a corresponding second group of comparators from the plurality of groups of comparators; and simultaneously performing data dependency detection on the first set of instructions associated with the first thread using the corresponding first group of comparators and performing data dependency detection on the second set of instructions associated with the second thread using the corresponding second group of comparators.

Detecting data dependencies of instructions associated with threads in a simultaneous multithreading scheme

A multiprocessor system providing transactional memory. A first processor initiates a transaction which includes reading first data into a private cache of the first processor, and performing a write operation on the first data in the private cache of the first processor. In response to detecting that prior to the write operation the first data was last modified by a second processor, the first processor writes the modified first data into a last level cache (LLC) accessible by the multiple processors. The system sets a cache line state index string to indicate that the first data written into the LLC was last modified by the first processor, invalidates the first data in the private cache of the first processor, and commits the transaction to the transactional memory system. This allows more efficient accesses to the data by the multiple processors.
