The number of A72 gates is 13 times that of A7! … Read more
Abstract The ARM Cortex-A72 has been around for nearly a decade since its release, widely appearing in devices such as the Raspberry Pi 4 and the first generation AWS Graviton, yet it has long lacked a mainline EDAC (Error Detection And Correction) driver for this core. Now, a driver named a72_edac has entered the edac-for-next … Read more
Click the above“Good Friends” to follow us with one click↑↑ If we were to identify Qualcomm’s biggest blunder in 2015, it would undoubtedly be the overheating Snapdragon 810 (high-end) and the mediocre Snapdragon 615 (mid-range) processors. At the end of December 2015, Qualcomm released two mid-range processors, the Snapdragon 618 and 620. To better introduce … Read more
