ABSTRACT:
A video controller integrated circuit is provided with an on-chip test data generator within the integrated circuit for emulating an external memory for testing purposes. When activated, the test data generator generates a pseudo-random data stream which is fed to the data input of a video memory controller within the integrated circuit. A signature generator, also within the integrated circuit generates a characteristic signature from the data stream which is compared to a characteristic signature from a known good integrated circuit.
