Title:
APPARATUS AND METHOD FOR PROCESSING DATA
Document Type and Number:
WIPO Patent Application WO/2018/059337
Kind Code:
A1
Abstract:
Disclosed is an apparatus for processing data, which can ensure the correctness of a function return address. The apparatus comprises: a return address predictor, an output selection circuit and a multiplexer, wherein the return address predictor comprises a plurality of address registers, the address registers correspond to skip link registers in a general register window on a one-to-one basis, and each address register is used for recording a function return address in the skip link register corresponding to each address register; the output selection circuit is used for receiving a CWP outputted by a processor, and according to the CWP, outputs a read selection signal, wherein the CWP is used for indicating a current general register window; and the multi-path selector is used for receiving the read selection signal and the function return address outputted by the address register, and according to the read selection signal, outputs a target function return address stored in a target address register to the processor, wherein the target address register corresponds to a target skip link register in the current general register window.
