ARM's Cortex-A7 and A15: A Performance Versus Power Consumption Optimization SchemeInside DSP - BDTiNov. 16, 2011 |
Last month's edition of InsideDSP included the article "NVIDIA and Qualcomm ARM Up Against Competitors," which discussed (among other things) NVIDIA's upcoming five-core Kal-El (i.e. Tegra 3) SoC. Tegra 3 combines four ARM Cortex-A9 cores built out of conventional 40 nm transistors and a fifth Cortex-A9 constructed from low-leakage (albeit switching speed-limited) circuits. The fifth core will operate stand-alone in low-performance usage scenarios (including, ironically, during high definition video playback sessions, thanks to the chip's dedicated-function hardware resources).
