Abstract

The typical operation of AV processing ICs includes an initialisation mode wherein registers are set up according to the desired functionality using dedicated set up software, and a normal decoding mode in which the content of the registers will not be changed any more. Often the initialisation mode software leads to un-initialised pointers and addresses for the registers. The writing of data in case of invalid pointers or address values can be avoided by additional small hardware for the register write access logic which enables or disables a write enable signal for distinct periods of time.
