Abstract: This application provides a matrix computing method, a chip, and a related device. The chip includes a first buffer, is configured to buffer a first vector, and a second buffer is configured to buffer a second vector. A scheduling module generates a selection signal based on a bitmap of the first vector. The selection signal may cause the processing element to obtain, from the first buffer, a group of non-zero elements in the first vector, and cause the processing element to obtain, from the second buffer, a group of elements in the second vector. An operation is performed between the first vector and the second vector based on the group of non-zero elements in the first vector and the group of elements in the second vector. In this application, an element whose value is 0 in one vector may be excluded from computing, to reduce a computing amount.

Abstract: A method and apparatus for synchronizing operations between a first circuit and a second circuit is disclosed. The method involves writing receive data from the first circuit to a first ring buffer at a first rate. The first ring buffer has a fixed-length of buffer elements and respective read and write buffer pointers. The buffered receive data is read from the first ring buffer to the second circuit at a second data rate. The respective positions of the read and write buffer pointers are detected, and a relative position between the read and write pointers is dynamically adjusted to enforce at least a predetermined minimum spacing. The dynamic adjustment comprises selectively adding or deleting portions of the data to or from the ring buffer.
