ABSTRACT:
Provided are a method and system for activating a design test mode in a graphics card having multiple execution units. A design test mode is activated in a graphics module comprising multiple execution units coupled to a cache on a bus. The bus is configured to return test instructions from the cache to the execution units in response to a request from one execution unit for the test instructions from the cache in the design test mode. The execution units execute the test instructions during the design test mode. Interrupts are prevented during the design test mode.
