An RISC processor and a method for converting and looking-up instruction address in the RISC processor. The device comprises a decoder, which includes a look-up table module for realizing the conversion from an X86 source instruction address to an MIPS target instruction address by using a look-up table. The look-up table module includes: a looking-up sub-module for indexing the look-up table based on content, wherein if looking-up is hit, the corresponding content will be stored in a target register, and if not, an entry address of the not-hit service program will be stored in the target register; and an indexing sub-module for indexing the look-up table based on content and getting an index of the table entry in which the content resides. |
