Front

The organizational changes in processor design have primarily been focused on increasing instruction-level parallelism so that more work could be done in each clock cycle.

Back

True

Front

With superscalar organization increased performance can be achieved by increasing the number of parallel pipelines.

Back

True

Front

The increasingly difficult engineering challenge related to processor logic is one of the reasons that an increasing fraction of the processor chip is devoted to the simpler memory logic.

Back

True

Front

The demand on power requirements has not grown as chip density and clock frequency have risen.

Back

False

Front

As chip transistor density has increased, the percentage of chip area devoted to memory has decreased.

Back

False

Front

The potential performance benefits of a multicore organization depend on the ability to effectively exploit the parallel resources available to the application.

Back

True

Front

Database management systems and database applications are one area in which multicore systems can be used effectively.

Back

True

Front

Even if an individual application does not scale to take advantage of a large number of threads, it is still possible to gain from multicore architecture by running multiple instances of the application in parallel.

Back

True

Front

An advantage of using a shared L2 cache on the chip is that data shared by multiple cores is not replicated at the shared cache level.

Back

True

Front

A potential advantage to having only dedicated L2 caches on the chip is that each core enjoys more rapid access to its private L2 cache.
