"NVIDIA опубликовала патчи для поддержки Tegra 3 в ядре Linux" Отправлено pavlinux, 01-Ноя-11 06:58
The Tegra 3 is functionally a quad-core processor, but includes a fifth "companion" core. All cores are Cortex-A9's, but the companion core is manufactured with a special low power silicon process. This means it uses less power at low clock rates, but more at higher rates; hence it is limited to 500 MHz. There is also special logic to allow running state to be quickly transferred between the companion core and one of the normal cores. The goal is for a mobile phone or tablet to be able to power down all the normal cores and run on only the companion core — using comparatively little power — during "standby" mode or when otherwise using little CPU. According to Nvidia, this includes playing music or even video content. Как всегда, для опенсоурса будет доступно только одно ядро, и именно то самое, которое low power silicon process и одно ядро GPU :)
