The system assures the proper operation of a programmable GPU. A list of shader programs is generated. A programmable GPU is instructed to render a set of graphic primitives to generate test image data into a test area of RAM of the GPU utilizing one of the listed programs. The GPU is instructed to combine test image data from the test area with normal image data to form a composite image as display image data. The data in the GPU RAM is output to an image processing unit (IPU), wherein the data is processed by the IPU. The IPU is utilized to apply a CRC algorithm to the test image data to calculate a check value. The calculated value is compared against a predetermined value for the test area. A fault is reported if the calculated check value does not match the predetermined value. These above steps are then repeated.

A calibration system for calibrating multi-channel sound systems. The calibration system includes a method for calibrating a sound system that includes a plurality of loudspeakers. The method includes steps of mapping the plurality of loudspeakers into a virtual loudspeaker system representation displayable to a user, activating at least one calibration function that creates a calibration signal that is reproduced by one or more of the plurality of loudspeakers to produce a calibration sound perceivable by the user, modifying the virtual loudspeaker system representation to include a virtual calibration indicator that indicates a characteristic of the calibration signal, and adjusting the virtual calibration indicator based on a user input, wherein when the virtual calibration indicator is adjusted, a corresponding adjustment is made to the characteristic of the calibration signal until a selected calibration sound is achieved.
