What Makes ARM Powerful

[vijay s]

what is the Unique Feature of ARM or What makes the ARM Powerful Microcontroller

 

[gomathigururajan]

ARM have some features that are code density, mmu,mpu, speed, low cost, scope is high... etc these makes ARM powerful....

 

[farhada]

Size, price, speed, low power

 

[Evan Chow]

High rate of costs

TO GOMATHI ANSWERS:

1. Code density in RISC machines are very poor. ARM does not have good code density. To improve code density, they introduced THUMB architecture in ARM.
This enabled the processor to execute code in 16 as well as 32 bit format. So speed increases.
2. Introducing cache memory, DMA controllers also increased speed.
3. Introduction of AMBA AXI the speed has also increased compared to normal AMBA bus.
4. Core CPU operating voltage has reduced to 0.9V in the latest ARM cores.
5. Less interrupt latency.
6. Configurable crystal oscillator
7. Pipelining stages
8. And all other features listed by others.
