![]() If there is ITCM,DTCM and MPU then there would not be CACHE and MMU.Įach block is explained below with respect to industrial control systems.ģ.1.1 Instruction Tightly Coupled Memory (ITCM) Note: In the classical series ITCM,DTCM,CACHE,MMU and MPU will not be in a single core. It does not cover in detail about the power management.ģ COMPARISON OF ARCHITECTURES Architectural Block Whether it is relevant to user for his requirements is left to the end user himself. During this process questions are raised for some modules. It tries to explain each module and the usability for industrial control systems. The classical ARM series refers to processors starting from ARM9 to ARM11. This paper brings out the architectural comparisons between and Classical ARM processors and cortex-M3. There are many papers on ARM today but most of them are related to comparison of performances or the improvements made over the previous Architecture. This paper gives brief comparison of the Architectures. A new entrant or Designer to the ARM can make use of this paper for easy understanding and choose a processor that is well suited for the requirements. Each set or groups of processors are having different core and different Features. ![]()
