MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -In computer architecture, 32-bit integers, memory addresses, or other data units are those that are 32 bits (4 octets or 4 Bytes) wide. Also, 32-bit CPU and ALU architectures are those that are based on registers, address buses, or data buses of that size.

Detailed explanation-2: -For a data bus, 32-bit means the number of pathways available, meaning that it has 32 pathways in parallel for data to travel. For microprocessors, it indicates the width of the registers and it can process any data and use memory addresses that are represented in 32-bits. This is part of the processor’s architecture.

Detailed explanation-3: -A 32-bit CPU can hold up to 34, 359, 738, 368 bits at a single time. However, data is typically denoted in groups of eight bits, which are known as bytes. Therefore, a 32-bit CPU can be used to process 4, 294, 967, 296 bytes, or 4 gigabytes (GB) at any given time. The term x86 is synonymous with 32-bit computer architecture.

Detailed explanation-4: -32-bit means that a microprocessor can execute 4 bytes of data in one instruction cycle while 64-bit means that a microprocessor can execute 8 bytes of data in one instruction cycle. Since microprocessor needs to talk to other parts of computer to get and send data i.e. memory, data bus and video controller etc.
