Arm Architecture Design

The ARM (Advanced RISC Machine) architecture is based on the principles of Reduced Instruction Set Computing (RISC), which prioritizes simplicity, efficiency, and high performance.

Notable design characteristics include:

• Load/Store Architecture: Interactions with memory and registers occur exclusively through load and store operations, keeping computation separate from memory access.

• Uniform Register Set: The use of a consistent set of general-purpose registers (R0-R15) and a Current Program Status Register (CPSR) streamlines processing and reduces system complexity.

• Conditional Execution: A majority of instructions can be executed based on the status flags, reducing the need for branching and minimizing overhead.

• Pipelining: ARM’s pipeline allows instructions to pass through stages such as fetch, decode, and execute, improving processing speed and throughput.

• Scalable Bit Sizes: ARM supports both 32-bit (ARMv7) and 64-bit (ARMv8) configurations, providing flexibility for a wide range of applications.

These elements combine to make ARM a fundamental component in contemporary computing.
