Core Concepts in ARM Architecture
ARM architectures are engineered for scalability and versatility, designed to meet the demands of applications ranging from small embedded systems to large-scale data centers. This article delves into the core components and features that make ARM's architecture so adaptable and powerful. We will explore four key areas
Introduction and Fundamentals of ARM: Understanding ARM's significance in the tech industry.
Instruction Set and Registers: How ARM's simplified instruction set works and thevital role of registers in ARM architecture.
Exception and Interrupts (GIC): How ARM handles exceptions and interrupts via the Generic Interrupt Controller.
Timers: How timers in ARM are used for tasks like measuring time intervals and counting events.
ARM Security Technologies: An introduction to security features like TrustZone.
Memory Management Unit (MMU): How ARM's MMU facilitates the mapping of virtual to physical memory addresses.
Cache Management: The significance of cache in enhancing system performance.
System Start-Up: The boot-up process of an ARM-based system from power-up to full functionality.
Virtualization in ARM: How ARM supports hardware virtualization.
Bus Architectures (AMBA/AXI/ACE): Types of data buses designed for connecting different components in an ARM-based system.
Advanced System Features: This section would delve into exclusive architectures, architectural timers, reset mechanisms, and SOC designs like DSU, WFE/WFI, etc.
