ARM 9 BOARD DEVELOPMENT PROJECT

The ARM family is the most advanced family of microcontrollers. Nowadays so many applications are developed based on ARM controllers and processors. The ARM stands for Advance Risk Machine. Currently many controllers and processors families are available like 8051, AVR, PIC, Motorola, etc, but still the ARM is very popular and is chosen for many applications and domains. There are many reasons for their in embedded based applications, such as their device functionality, set of peripherals and high speed data processing.

The ARM manufactures each add their own mixture of peripherals and add on functionality to the chip. Many chips with ARM family include a A/D converters, counters/timers, capacitive touch controller, LCD controller, USB, Wi-Fi base band etc; there are already built into the chip. This saves on port cost, design time and physical space on the circuit board. Most of the companies prefer to use ARM families over and over again. The ARM9 and ARM7 are the most popular in ARM families.

ARM9 Development Board

The ARM9 is a high performance ARM controller/processor. It has a high efficiency, dual issue sub scalar and a dynamic length pipe line (8-11 stage). It has light weight workload as well as peak performance. The ARM9 performance is better than ARM7. It is currently used in smart phones and digital TV, consumer electronics and enterprise applications.
