Cortex-A7和Cortex-A15, 核心尺寸差异达到了6倍,性能的差别同样很大。 性能对比 Cortex-A7 block diagram 将这个与目前的ARMCortex-A系列,Qualcomm的Krait相比的话,首先可以看到Cortex-A15和Krait级4核心产品,即使使用28nm工艺,其核心面积依然会很大。而早年基于40nm工艺Cortex-A9双核, 其尺寸为5～7平方mm左右。
Arm Cortex-M0+ block diagram Key advantages of Arm® Cortex®-M0+ MCUs The small footprint of the core allows it to be used as a single core in small devices, but also as an additional embedded companion core when specific hardware isolation or task partitioning is required. The Cortex...

Arm Cortex-M33 block diagram (source:Arm) Key advantages of the Arm® Cortex®-M33 core Armv8-M architecture The Cortex-M33 benefits from the Armv8-M architecture. This architecture implements programmer models designed for low-latency processing and provides the option to implement a memory...
这里compatible的名字使用了armv7、armv8这样的字样而不是Cortex A15,我猜测ARM公司是认为这样的generic timer的硬件block是ARMv7或者v8指令集的特性,所有使用这些指令集的core都应该使用这样的generic timer的硬件结构。不论是v7还是v8,其初始化函数都是一个arch_timer_init。从这个角度看,把ARM的generic timer的驱动...
