could deliver better performance than the existing microprocessors while maintaining low

power consumption. The result was the development of a Reduced Instruction Set

Computing (RISC) processor—a concept focusing on a simpliﬁed set of instructions that

can be executed rapidly and eﬃciently.

In 1985, ARM1, the ﬁrst prototype chip, was born, marking the beginning of a new

architecture designed for eﬃciency rather than sheer processing power. This design

philosophy distinguished ARM from other processors, most notably the complex

instruction set computing (CISC) architectures prevalent at the time, such as Intel’s x86.
