Abstract: A gaming device includes a display device, an input device, a processor circuit, and a memory. The memory includes machine-readable instructions that, when executed by the processor circuit, cause the processor circuit to receive, by the processor circuit and via an operator processing circuit, identification corresponding to multiple game sets. Each of the game sets may include a subset of games. The processor circuit is caused to determine a recommended game set switch from a first game set to a second game set. The first and second game sets are on an electronic gaming machine (EGM) and the determining is performed using artificial intelligence that uses external data to identify the second game sets. The processor circuit is caused to transmit, to the EGM, an identification of the recommended game set switch.

Abstract: Systems and methods for computer memory management by a memory coordinator and a plurality of memory consumers. An urgency and memory quota of each memory consumer is initialized by the memory coordinator, which then adjusts the memory quota of each memory consumer such that the sum of the memory quota of each memory consumer does not exceed a finite amount of computer memory. Each memory consumer adjusts its memory usage in response to the quota input and urgency input from the memory coordinator.

Abstract: Commands in a command queue are received and scheduled. For each of the commands, scheduling includes determining an age of a command based on an entrance time of the command in the command queue. When the age of the command satisfies a first threshold, marking all other commands in the command queue as not issuable when the command is a deterministic command, and marking all other commands in the command queue as not issuable when the command is a non-deterministic command and the intermediate command queue is not empty. Scheduling the command further includes determining whether the command is a read command and marking the command as not issuable when the command is a non-deterministic read command and the intermediate command queue is empty.

Abstract: A system may include a memory and memory controller configured to communicate with the memory over two or more channels. The memory controller may have a buffer with buffer locations distributed across memory channels, and may be configured to receive a write command for writing current data to a memory location within the memory and may be configured to determine whether to buffer data and/or parity, and configured to write the current data or the current parity in the buffer when it is determined to be stored in the buffer. As the buffer is faster and uses less power, the reduction in back-end accesses improves performance and reduces power consumption.

Abstract: Systems and methods for finite time counting period counting of infinite data streams is presented. In particular example systems and methods enable counting row accesses to a memory media device over predetermined time intervals in order to deterministically detect row hammer attacks on the memory media device. Example embodiments use two identical tables that are reset at times offset in relation to each other in a ping-pong manner in order to ensure that there exists no false negative detections. The counting techniques described in this disclosure can be used in various types of row hammer mitigation techniques and can be implemented in content addressable memory or another type of memory. The mitigation may be implemented on a per-bank basis, per-channel basis or per-memory media device basis. The memory media device may be a dynamic random access memory type device.

Abstract: Systems and methods that provide a mechanism to transition static schema to dynamic schema while maintaining backwards capability. Simple removal of static schema elements, followed by replacement with dynamic schema elements, make a third-party code incompatible since the third-party code references schema entities that no longer exist. Provided is a mechanism to decrease the memory use of non-material static schema entities. Transitioning static schema to dynamic schema allows the database to avoid loading non-material schema entities, thereby decreasing overall memory usage.

Abstract: A tournament time period is determined for a wagering game tournament, and a plurality of tournament entries are received from a plurality of players during the tournament time period. For each tournament entry, a tournament initiation instruction is received from the player playing a base wagering game at a gaming device, game play data for the base wagering game is received from the gaming device during the tournament time period, and a tournament score for the player is determined based on the play data and a tournament parameter. After the tournament time period, the plurality tournament scores for the plurality of players are evaluated, and a tournament prize is awarded to a player of the plurality of players based on the evaluation of the tournament scores.

Abstract: A method and apparatus for inscribing a Bragg grating in the core of an optical waveguide. Electromagnetic radiation at a chosen wavelength passes through a diffractive optical element optimized for the wavelength such that a beam is generated on the waveguide having an interference pattern so as to form a Bragg grating in the core of the optical waveguide, the beam being sufficiently intense to cause a permanent (Type II) change in the index of refraction in the core in the form of at least one elongated micropore. The Bragg grating period can be selected to promote coupling of guided light into a radiation mode for detection by a detector to form a spectrometer. The Bragg grating is characterized by a scattering loss less than 10?5 dB per grating period at the Bragg resonance but outcoupling efficiency at visible wavelengths of 0.03% per grating period.

Abstract: A variety of applications can include memory or memory sub-systems having a memory-centric protocol with dedicated unidirectional serialized interfaces in the two directions of the interface for the memory or the memory sub-systems. The unidirectional serialized interfaces can be realized by dedicated pins on the devices connected by the devices. The memory-centric protocol with dedicated unidirectional serialized interfaces can support both deterministic and non-deterministic timed input/output to media and memory sub-systems.

Abstract: Described apparatuses and methods relate to a write request buffer for a memory system that may support a nondeterministic protocol. A host device and connected memory device may include a controller with a read queue and a write queue. A controller includes a write request buffer to buffer write addresses and write data associated with write requests directed to the memory device. The write request buffer can include a write address buffer that stores unique write addresses and a write data buffer that stores most-recent write data associated with the unique write addresses. Incoming read requests are compared with the write requests stored in the write request buffer. If a match is found, the write request buffer can service the requested data without forwarding the read request downstream to backend memory. Accordingly, the write request buffer can improve the latency and bandwidth in accessing a memory device over an interconnect.

Abstract: A video lottery system may include a processor circuit and a memory coupled to the processor circuit. The memory comprises machine-readable instructions that, when executed by the processor circuit, cause the processor circuit to obtain, by a mobile player device associated with a player, site controller information from a local site controller associated with a video lottery terminal (VLT). The instructions further cause the processor circuit to transmit, by the mobile player device, a network request to a remote server for player information from a player database. The instructions further cause the processor circuit to receive, by the mobile player device from the remote server, the player information. The instructions further cause the processor circuit to provide, by the mobile player device, the player information in an encoded format to the local site controller.
