The article discusses the use of Cell processor in consumer electronics. Current consumer electronics must be powerful, flexible, and efficient. The Cell processor has multiple processor cores on the chip, and meets those requirements with an abundance of computation power, flexibility, and energy efficiency. An application running on consumer electronics is usually real-time, and thread scheduling is important to meet real-time constraints. On the other hand, real-time systems must consider power management features such as shut down and slow down when assigning threads to the processor cores. Because of the transition overhead that power management features have, thread assignment must be careful to reduce the number of transitions. For consumer electronics, power consumption of the mediaprocessor is the important feature. The Cell processor's implementation considers the efficiency of power consumption and has power management features. On the other hand, for consumer electronics as real-time systems, the execution timings of an application's threads are critical to stabilizing the application. |
