The ARM is a 32-bit processor that uses a reduced instruction set computer (RISC) architecture. The manufacturer and developer is by ARM Holdings. The ARM architecture is a widely used 32-bit ISA based on the numbers produced. Because the ARM processors are relatively simple, this has made them suitable for low power applications. In that regard, this has made them dominant player in the mobile and embedded electronics market. They have a relatively low cost, and low energy consumers.
There are about one billion mobile phones around the world and about 98 percent sold each year use at least one ARM processor. Since 2009, ARM processors have accounted for almost 90% of all embedded 32-bit RISC processors. ARM processors are low power chipsets so they appear in a variety of consumer electronics. These include PDAs, digital media, mobile phones, and music players, calculators , hand-held game consoles, and computer peripherals such as hard drives and routers.
