Abstract: An asynchronous instruction execution apparatus and method are provided. The asynchronous instruction execution apparatus includes a vector execution unit control VXUC module and n vector execution unit data VXUD modules, where n is a positive integer. The VXUC module is configured to perform instruction decoding and token management. The n VXUD modules are cascaded, separately connected to the VXUC module, and configured to invoke an external calculation resource to perform data calculation. A bit width of data processed by the asynchronous instruction execution apparatus is M, a bit width of each VXUD module is N, and n=M/N. The asynchronous instruction execution apparatus is divided into two parts: the VXUC and the VXUD.

Abstract: Embodiments of this application disclose a polar coding method, apparatus, and device, so as to reduce storage overheads of a system. A sequence for polar coding is obtained based on a length M of a target polar code, wherein the sequence comprises L sequence numbers, ordering of the L sequence numbers in the sequence is the same as ordering of the L sequence numbers in a maximum mother code sequence, wherein the maximum mother code sequence is obtained by sorting N sequence numbers of N polarized channels in ascending order or descending order of reliability metrics, wherein L and N are integer power of 2, M is smaller than or equal to L, L is smaller than or equal to N.
