Abstract

The invention relates to a method for the operation of a data processing unit (2), which reads data on demand from a provided storage unit (4), by recourse to specifically deposited target addresses, whereby the target addresses given by the data processing unit (2) are converted into an actual address by means of a deposited encoding algorithm, before an access to the storage unit (4) occurs.
