MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -The ARM Advanced Microcontroller Bus Architecture (AMBA) is an open-standard, on-chip interconnect specification for the connection and management of functional blocks in system-on-a-chip (SoC) designs.

Detailed explanation-2: -The ARMv7 architecture is a 32-bit processor architecture. It is also a load/store architecture, meaning that data-processing instructions operate only on values in general purpose registers. Only load and store instructions access memory. General purpose registers are also 32 bits.

Detailed explanation-3: -These are the Advanced High-Performance Bus (AHB), the Advanced System Bus (ASB), and the Advanced Peripheral Bus (APB).

Detailed explanation-4: -The ARM cortex microcontroller is a 32-bit microcontroller therefore all instructions are 32-bit long which is executed in a single cycle. It consists of an instruction set to perform the arithmetic, logical and boolean operations. The ARM is a load-store architecture, then instructions are executed conditionally.
