Abstract: Embodiments of the present disclosure relate to debugging of an accelerator circuit using a packet limit breakpoint. A vector circuit reads a subset of instruction packets from an instruction memory and receives a portion of input data from a data memory corresponding to the subset of instruction packets. The vector circuit executes a set of vector operations in accordance with multiple instruction packets from the subset using data from the received portion of input data identified in the multiple instruction packets to generate output data. A program counter control circuit coupled to the instruction memory triggers a breakpoint in a program stored in the instruction memory causing the accelerator circuit to stop executing remaining instruction packets in the program following the multiple instruction packets responsive to a number of instruction packets executed in the program from a time instant of an event reaching a predetermined number.

Abstract: Embodiments of the present disclosure relate to selecting a subset of keypoint descriptors of two images for match operation based on their orientation angles indicated in headers of the keypoint descriptors. The keypoint descriptors in the two images are matched by first comparing their headers and then performing vector distance determination. During the header comparison operation, a header of a descriptor of a first image is compared only with headers of keypoint descriptors of a second image in a discrete orientation angle range corresponding to an orientation angle indicated by the header of the first image descriptor or keypoint descriptors of the second image in adjacent discrete orientation angle ranges. After the headers of the keypoint descriptors satisfying one or more matching criteria are determined, distance determination operations are performed between the keypoint descriptors while the remaining keypoint descriptors are discarded without determining their distances.
