Abstract: Random numbers within a processor may be scarce, especially when multiple hardware threads are consuming them. A local random number buffer can be used by an execution core to better manage allocation and consumption of random numbers. The buffer may operate in a number of modes, and allow any hardware thread to use a random number under some conditions. In other conditions, only certain hardware threads may be allowed to consume a random number. The local random number buffer may have a dynamic pool of entries usable by any hardware thread, as well as reserved entries usable by only particular hardware threads. Further, a user-level instruction is disclosed that can be stored in a wait queue in response to a random number being unavailable, rather than having the instruction's request for a random number simply be denied. The random number buffer may also boost performance and reduce latency.

Abstract: A method for effectively transmitting data, in which a switch is connected between a plurality host and storage, comprises steps of the following. First, the hosts recognize the storages via the switch, and revise a data transmission path within an original command, meanwhile transforming it into a specific command. Later, the switch receives the specific command, alternatively revises the data transmission path or not, and transforms the specific command into a standard command. The standard command is then transmitted to the storage. After receiving it, the storage is able to search for a corresponding host based on the data transmission path such that data is simply transmitted between the storage and its corresponding host. By employing the proposed method, the present invention is beneficial to reducing system complexity and raising data transmission efficiency.

Reducing the time required for a data transfer may allow for low power modes to be used, which in turn further saves power.

Abstract: Described herein are various systems and methods to automatically decide to aggregate data write requests in a distributed data store. A system initiates outgoing data write requests in synchronization with incoming data store commands, thereby facilitating low-latency read-back of the data. In response to an absence of data read requests, the system automatically changes such that each request includes two or more data sets, thereby breaking synchronization but consequently reducing traffic load on a switching network within the system. If the system later detects data read requests for previously stored data, the system will automatically change back to the original synchronized state, thereby decreasing the latency of accessing stored data. The system alternates between the modes of operation to achieve balance between low latency of data access and reduced traffic load on the switching network.

Abstract: Frames of a video stream can be partitioned using source difference variance based partitioning before encoding. Variances between blocks of a current video frame and blocks of a previous unencoded video frame are determined. The current video frame can be partitioned into varying block sizes depending upon the magnitude of the variances. Blocks with low variance may be combined with other low variance blocks to form larger blocks, while blocks with high variance may be further partitioned into smaller blocks to improve encoding efficiency of the blocks. In cases where partitioning of a frame is unlikely to provide improved efficiency, the variation calculations may be skipped in favor of using fixed partitioning.
