The Android emulator accomplishes its work through an open source “processor emulator”
technology called QEMU ( developed by Fabrice Bellard. This

of the processor. QEMU allows emulation at the CPU level.

In the case of the Android emulator, the processor is based on ARM (Advanced RISC
Machine). ARM is a 32-bit microprocessor architecture based on RISC (Reduced Instruction
Set Computer), in which design simplicity and speed is achieved through a reduced number of
instructions in an instruction set.
