Original Abstract Submitted
A system, method, and apparatus are provided for verifying functional safety of an image signal processor (ISP) by configuring one or more edge pattern settings in a test pattern generator; activating the test pattern generator to generate test pattern data by modulating a sequence of pseudo random number values with a sequence of values from an edge pattern; processing the test pattern data at the ISP to generate ISP test output data; generating a checksum value of the ISP test output data; and comparing the checksum value with a reference checksum value to verify a functionality of the ISP.
