先决条件–微控制器(µC)和微处理器(µP)之间的差异

微控制器是一个单集成电路(IC),可与一台小型独立计算机相提并论,它旨在管理嵌入式系统中的特定操作。一个微控制器包含处理单元和少量的内存(ROM,RAM等),用于外围设备的I / O端口,计时器等。我们可以说这是一个小型且低成本的微型计算机。 ARM和PIC属于微控制器家族。 PIC微控制器和ARM微控制器在不同的体系结构以及不同的指令集,速度,转换,内存,功耗,总线宽度等方面彼此不同。现在,让我们详细了解它们之间的区别。

1. PIC微控制器:
PIC单片机最初被称为外围接口控制器,现在被称为可编程智能计算机。它属于Microchip Technology制造的微控制器家族。它最初是由通用仪器公司的微电子学于1993年开发的。可以对其进行编程以执行各种各样的任务。 PIC微控制器提供8位,16位和32位版本。它基于RISC指令集体系结构和Havard内存体系结构。

2. ARM微控制器:
ARM微处理器是由Acron计算机组织引入的Advanced RISC Machine,由Apple,Nvidia,Qualcomm,Motorola,ST Microelectronics,Samsung Electronics和TI等公司制造。ARM处理器属于基于CPU的家族在精简指令集计算机(RISC)和ARM微处理器(在一个芯片上具有RAM,ROM和其他外围设备)上,我们得到了一个ARM微控制器。 LPC2148是ARM微控制器的一个示例。它基于RISC指令集体系结构(ISA)。它是成本敏感的高性能设备,并广泛用于工业应用控制系统等嵌入式应用中。
