Abstract: Apparatus, systems and methods for irrigating lands are disclosed. In one example, an irrigation system is disclosed. The irrigation system includes a gate and a microcontroller unit (MCU). The gate is configured for adjusting a water flow for irrigating a piece of land. The MCU is configured for controlling the gate to adjust the water flow based on environmental information related to the piece of land.

Abstract: Power and performance of a multi-core system is managed dynamically by adjusting power table indices at runtime. Runtime statistics is measured, when an application is executed on a first core of a first type at a first operating point (OPP) in a first time period, and on a second core of a second core type at a second OPP in a second time period. A controller estimates, based on the runtime statistics, a first pair of indices associated with a first OPP for the first core and a second pair of indices associated with a second OPP for the second core. During runtime, the controller incorporates the first pair of indices and the second pair of indices into power table indices; and determines, from the power table indices, selected indices associated with a selected OPP of a core of a selected core type for executing the application.

Abstract: A data-processing apparatus and an operation method thereof are provided. The data-processing apparatus includes a tiling circuit and a post-stage processing circuit. The tiling circuit is configured to receive input data. The tiling circuit divides a current frame of the input data into at least one tile and checks a motion state of the current tile in the at least one tile. The post-stage processing circuit is coupled to the tiling circuit to receive the current tile. The post-stage processing circuit performs post processing on the current tile to generate a processed current tile of the current frame or to obtain a processed corresponding tile of a previous frame and serves it as the processed current tile of the current frame, according to the motion state of the current tile.

Abstract: An exemplary embodiment describes a method for tile elimination, including: reading in data of a new tile; reading signature values corresponding to the new tile from a signature value repository; generating signature values for the new tile; comparing the read signature values and the generated signature values of the same tile to determine whether the two sets of signature values being identical; when the two sets of signature values being identical, copying the new tile directly from a tile frame buffer without rendering; otherwise, updating the signature value repository with the generated signature values replacing the stored signature values; rendering the tile; and updating the tile frame buffer with the newly rendered tile.
