Circuits and Methods for Replacing Defective Instructions |
摘要 |
An address selector replaces an address pointing to a defective instruction in a built-in firmware. The address selector includes a comparing unit and a multiplexer. The comparing unit provides a comparison result by comparing a current address received from a processor with a predetermined address pointing to the defective instruction. The multiplexer coupled to the comparing unit receives a backup address pointing to a backup instruction, and the current address and if the current address matches the predetermined address, selects the backup address such that the current address is replaced by the backup address
