Summary

The end of an era is approaching. For over 30 years the technology industry has relied on exponential improvements in microprocessor technology, described by Moores Law, to deliver ever-increasing computing power at an ever-decreasing size and cost. However, chip makers have reached a plateau, preventing additional jumps in performance using existing techniques. In addition, consumers are demanding increasingly sophisticated high-end devices with advanced multimedia capability without degrading battery life. The solution to this problem is the adoption of new processors that use symmetric multi-processing (SMP). SMP processors use multiple CPUs within a single chip to deliver extra horsepower. However, there is a cost to this new approach: it increases the complexity of software development, which in turn will impact time-to-market for new devices and services. It will also affect software quality, increasing the likelihood of device returns and increasing support costs for service providers.
