Latest Patents

One of Guoyi Yu's latest patents is a "Hardware acceleration method and system based on scale-invariant feature transform algorithm." This invention focuses on enhancing the hardware acceleration design of algorithms. The architecture consists of two main components: keypoint detection and descriptor generation. By utilizing four buffers that ping-pong between these components, the system achieves increased processing speed. In the keypoint detection phase, multi-layer Gaussian pyramids and Gaussian difference pyramids are calculated in parallel, leading to the extraction of keypoints along with their gradient magnitudes and orientations. The descriptor generation phase employs a circular keypoint region division strategy, allowing for parallel calculations of the main orientation and descriptor generation modules. The final output is produced through a descriptor rearrangement and dimensionality reduction module.

Another notable patent by Yu is the "Reconfigurable hardware acceleration method and system for Gaussian pyramid construction." This invention pertains to the design of hardware accelerators. The system includes various components such as a static random access memory (SRAM) bank, a FIFO group, a switch network, and a reconfigurable processing element (PE) array. The reconfigurable PE array can be adjusted according to the requirements of different tasks, enabling convolution calculations of varying scales. This patent also introduces methods for dual clock domain design, dynamic edge padding, and input image partial sum reuse.
