General ARM Chip Diagram Port-0 and Port-1 are 32-bit Input/output ports, and every bit of these ports can be controlled by an individual direction. The Java Virtual Machine performs the complicated operations in software while the Java bytecodes are usually run on hardware. The instruction set Thumb-2 is supported by all the ARMv7 chips. The code density resembling the Thumb is achieved by the Thumb-2 and also its performance is similar to the ARM instruction set on a memory of 32 bit. Also used at the research level in particle accelerators, nuclear reactors and X-ray cargo scanning applications. The ARM architecture processor is an advanced reduced instruction set computing [RISC] machine and it’s a 32bit reduced instruction set computer (RISC) microcontroller. The Thumb-2 technology was introduced on ARM1156 core and it was announced in the year 2003. New instruction set was added to improve the architecture of ARM for multimedia applications and digital signal processing. It has low power modes. This processor is tremendous in finding the resources existing on the internet with excellence documentation offered by NXP Semiconductors. The Arm® Cortex®-M0 is the smallest Arm® processor available, with a very small silicon area, low gate count, low power and minimal code footprint. These cores are optimized for low-cost and energy-efficient microcontrollers, which have been embedded in tens of billions of consumer devices. 5 volts tolerant quick general purpose Input/output pins in a small LQFP64 package. The thumb mode has been featured by the processors from ARM7TDMI to help in improving the compiled code density.
