DSP touts low power consumption, low price

摘要

CPUs with DSP-targeting instruction-set extensions and hardware-acceleration blocks are increasingly able to implement the types of functions that historically required a discrete DSP IC. Look, for example, at the AVX (advanced-vector-extension) enhancements of Intel's latest Sandy Bridge microarchitecture, which the company highlighted at last month's Intel Developer Forum, or at the multimedia-processing capabilities of the A4 CPU in Apple's iPad.
