    摘要: 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.

    摘要: Provided are a method and system for loading test data into execution units in a graphics card to test the execution units. Test instructions are loaded into a cache in a graphics module comprising multiple execution units coupled to the cache on a bus during a design test mode. The cache instructions are concurrently transferred to an instruction queue of each execution unit to concurrently load the cache instructions into the instruction queues of the execution units. The execution units concurrently execute the cache instructions to fetch test instructions from the cache to load into memories of the execution units and execute during the design test mode.

    摘要: An integrated circuit having a central built-in self-test unit (BIST) that uses internal scan chains for testing embedded memory modules. The embedded memory modules receive address and data signals from a set of input flip-flops configured to form a scan chain. The BIST is coupled to an input scan chain and includes a pattern generator to shift a test pattern into the input scan chain for testing the embedded memory modules. Output flip-flops capture data from the embedded memory modules are also configured as a scan chain. The BIST includes address control logic to bypass the normal addressing logic of the embedded memory module when the BIST operates is operating in a memory test mode.
