Abstract: An instruction cache, a circular buffer and a method for controlling access of the instruction cache are provided. The instruction cache includes an instruction cache bank, a circular buffer and a selection circuit, where the selection circuit is coupled to the instruction cache bank and the circular buffer. The instruction cache bank is configured to store instructions for a processor. The circular buffer is configured to store a portion of the instructions, where access speed of the circular buffer is faster than access speed of the instruction cache bank. The selection circuit is configured to select one of a first instruction from the instruction cache bank and a second instruction from the circular buffer to be output as an output instruction for the processor according to whether a read address is found in the circular buffer or not.

Abstract: A rapid monitoring and discrimination method for drought conditions in summer maize based on chlorophyll content includes: 1) Obtaining multi-spectral imagery through UAV multi-payload low-altitude remote sensing technology and measuring chlorophyll content on the ground. Additionally, calculating vegetation indices including Normalized Difference Vegetation Index (NDVI), Soil-Adjusted Vegetation Index (SAVI), and Renormalized Difference Vegetation Index (RENDVI). 2) Selecting vegetation indices and constructing regression equations with measured chlorophyll content during different growth stages. The regression equation with the highest correlation for each growth stage is chosen as the optimal model equation for that particular stage. 3) Using the optimal model equations to retrieve chlorophyll content for each period and determining thresholds for chlorophyll content across different drought levels through calibration.

Abstract: Methods and systems for correcting position errors for a multi-leaf collimator (MLC) are provided. A method may include determining a first position for each of the plurality of leaves. The information associated with the first position may include a first movement direction and a first angle. A movement of the each of the plurality of leaves along the first movement direction may be configured to move toward or away from a center of the radiation field. The method may also include determining an offset value associated with the first position based on the first angle and the first movement direction; and determining a target position of the each of the plurality of leaves based on the offset value.

Abstract: A method for transmitting video data and haptic data between a mobile video acquisition device and a remote computer through a communication network, and a video acquisition device. A server capable of direct communication exists in the communication network. The video data can be presented on a screen of the remote computer for a user to view, and the haptic data can be used to control a motion state of the video acquisition device acting as an avatar of the user. In the present invention, a first channel for transmitting video data and a second channel for transmitting haptic data are established between a computer having access to the Internet and a video acquisition device having access to the Internet by using a server and through a P2P technology. The present invention enables forming of a low-cost long-distance avatar network of multiple users versus multiple avatars, thereby greatly reducing travel of people, and contributing to low carbon environmental protection.
