ARM v7的体系结构A、R、M区别,分别应用在什么领域?
2022-07-01 08:31:00 【匠在江湖】
ARM v7的体系结构可以分为 A, R, M 三种版本(款式)
Contex-A系列面向密集型系统的应用处理器内核。顶级主控,在手机,平板,GPS普遍应用,移动设备芯片90%都是使用arm。与arm9和arm11相对应,都是可以跑操作系统系统的如linux等。
Contex-R系列面向实时应用的高性能内核。主要应用于对实时性较高的场合,如硬盘控制器、车载控制产品等。
Contex-M系列面向各类嵌入式应用的微控制器内核(相当于高级单片机)。主要应用工业、消费领域。与arm7相似,不能跑大操作系统(只能跑类似uCos2实时操作系统)。
