Line 9:
All of processors you'll see in tablets or smartphones are SoCs which act as sort of motherboard with a processor. They contain logic for driving peripherals (ethernet, USB, SD/MMC cards, SPI, I2C, audio), they may contain GPU for graphics coprocessing or FPGA for custom logic.
Many uses means either few multifunctional (and theferefore complex and power-consuming) devices, or many simple devices suited just for that kind of operation. ARM processors as RISC devices chose simplicity over complexity, and therefore they are way too many cores with different instructions used. To have just ''one assembler to rule them all'', ARM defined Unified Assembly Language which can be translated for
ARM cores are divided in lastest versions to three main lines:
