The application discloses a gamma correction method, a display device, a storage medium and a program product, relates to the technical field of image display, and the method is applied to the display device, and the method comprises the following steps: in the case that a target display brightness adjustment instruction is detected, a target reference display brightness corresponding to a target display brightness is determined, the target display brightness adjustment instruction is used for adjusting the current display brightness of the display device to the target display brightness; a gamma lookup table and a gamma reference voltage corresponding to the target reference display brightness are acquired from a gamma correction parameter storage area of the display device, and the gamma lookup table and the gamma reference voltage corresponding to the target reference display brightness are determined based on the gamma lookup table and the gamma reference voltage corresponding to the target reference display brightness; in the case that the current display brightness of the display device is adjusted to the target display brightness, gamma correction is performed based on the gamma lookup table and the gamma reference voltage corresponding to the target display brightness. The application can improve the processing efficiency and real-time performance of gamma correction.

This invention discloses a motion planning method for a seven-DOF robotic arm system, comprising a six-DOF robotic arm and a guide rail. The method first obtains key configuration parameters, dividing the system's revolution angle around a fixed point into n regions and establishing a one-to-one mapping with n predetermined positions on the guide rail. These parameters include the boundary angles of each region, the corresponding guide rail positions, and floating thresholds set for both to suppress fluctuations in region boundary identification caused by floating-point precision. Subsequently, the current revolution angle and guide rail position are identified to determine the target revolution angle. Based on the region numbering relationship between the current and target angles and the current guide rail position, a motion path is adaptively generated. This path is achieved through asynchronous coordination of the robotic arm joint motion and the guide rail linear motion, maintaining a constant end-effector posture throughout the process. This invention avoids real-time kinematics solving through discretization and parameter mapping, improving planning stability, system adaptability, and motion efficiency.

This invention relates to the field of digital information transmission security and discloses a design method for an SM2 hardware accelerator resistant to side-channel attacks in an RTOS. The method includes: constructing an absolute time window strictly aligned with the communication time slot period based on a bus synchronization clock; monitoring the SM2 operation progress within the window and automatically triggering an isochronous flow control unit upon completion of the actual instruction; this unit drives the operation core to perform twin pseudo-instruction filling on irrelevant data, isomorphic to the actual instruction, until the window terminates and the result is output. This invention physically shapes non-constant-time cryptographic operations into carrier signals with fixed timing and continuous equal-amplitude power envelopes, eliminating feature leakage in differential power analysis and ensuring that the hardware accelerator presents a zero-jitter, time-rigid node to the RTOS, thus meeting the stringent requirements of deterministic transmission in industrial time-sensitive networks.
