In a computer system bytes passing from a store to a processor pass through a memory (PROM). The contents of locations of the memory which are addressed by data bytes and most operation codes are equal to the respective data bytes and operation codes by which they are addressed so that the memory is transparent to them. However, the contents of some locations are not equal to the op-codes by which they are addressed so that those operation codes are converted into different operation codes. |
