ABSTRACT:
The invention provides an apparatus and a method for converting instructions of a code A to instructions of a code B. Said conversion is performed by obtaining rearrangement information, which corresponds to the instruction that is to be converted, from a table. Said rearrangement information is then used to rearrange the instruction elements of the initial instruction, in order to generate instructions of code B, which functionally corresponds to said initial instruction. Said rearrangement can be performed by multiplexing means, which use said instruction elements of the initial code A instruction as input, and which select one of said instruction elements, or the content of another register, and forward this selected data to the instruction that is to be generated. Said rearrangement information is directly used to control the selection performed by said multiplexers.
