An UART interface circuit is provided in the invention. The UART interface circuit is configured in an electronic device. The UART interface circuit includes a baud-rate generating circuit, a control circuit, and a receiving circuit. The baud-rate generating circuit is configured to generate a baud rate and a start-bit cycle. The control circuit obtains the wakeup stable time from the wakeup time circuit of the electronic device and obtains the start-bit cycle from the baud-rate generating circuit. The receiving circuit is configured to capture data from the start bit or the first data bit of UART data. When the electronic device is woken up by the UART data, the control circuit compares the start-bit cycle with the wakeup stable time to direct the receiving circuit to start capturing data from the start bit or the first data bit of the UART data.

In one aspect, a method for determining a target quantum state includes the actions of receiving data representing a target quantum state of a quantum system as a result of applying a quantum circuit to an initial quantum state of the quantum system; determining an approximate quantum circuit that approximates the specific quantum circuit by adaptively adjusting a number of T gates available to the specific quantum circuit; and applying the determined approximate quantum circuit to the initial quantum state to obtain an approximation of the target quantum state.

In a processor device according to the present invention, a memory access unit reads data to be processed from an external memory and writes the data to a first register group that a plurality of processors does not access among a plurality of register groups. A control unit sequentially makes each of the plurality of processors implement a same instruction, in parallel with changing an address of a register group that stores the data to be processed. A scheduler, based on specified scenario information, specifies an instruction to be implemented and a register group to be accessed for the plurality of processors, and specifies a register group to be written to among the plurality of register groups and data to be processed that is to be written for the memory access unit.

A method for using a distributed game engine includes receiving a request from a user account via a computer network to play a game, identifying processing power assignment for the user account, and determining node assembly for the user account to utilize two or more processing nodes for the play of the game based on the processing power assignment. The method further includes initializing the two or more processing nodes for execution of the game for the user account. The operation of initializing is performed to set up a transfer of processing code for the game from one processing nods to another processing node. The method includes defining an internal communication channel between the two or more processing nodes for exchange of state information of the game. The exchange of state information is performed to enable shared processing of the game by the two or more nodes.

State machine generation for a multi-buffer electronic system can include receiving, using a processor, a user input specifying a reader policy and a number of a plurality of buffers used by a reader and a writer of the multi-buffer electronic system. A state machine can be generated as a data structure. The state machine has a plurality of states determined based on the number of the plurality of buffers and the reader policy. The state machine allocates different buffers of the plurality of buffers to the reader in temporally accurate order over time. Each state can specify an allocation from the plurality of buffers to the reader and the writer. A state machine description including one or more program code components can be generated, where the one or more program components may be used in an implementation of the reader and an implementation of the writer.

The disclosure relates to detecting phase slips that may occur in a multi-lane serial datalink. Phase slips may occur when a lane experiences lane skew, which may introduce a phase slip with respect to another lane. To detect phase slippage, the system may select a reference lane from among the lanes. The system may generate a pre-deskew delta value based on a difference between the FIFO filling level of the reference lane before a deskew and the FIFO filling level of a second lane before the deskew. The system may generate a post-deskew delta value based on a difference between the FIFO filling level of the reference lane after the deskew and the FIFO filling level of the second lane after the deskew. The system may use a difference between the post-deskew delta and the pre-deskew delta to detect phase slip on the second lane relative to the reference lane.
