Today, we are discussing microprocessors, which are the brains of our machines, operating as central processing units on a single integrated circuit. Can anyone tell me what functions we expect from a microprocessor?
They perform arithmetic and logic operations!
Exactly! These operations are executed by the ALU, which stands for Arithmetic Logic Unit. Can anyone tell me the components we find in a microprocessor?
I think I heard about registers and buses?
Yes, precisely! Registers provide quick storage for process data, and buses are pathways for transferring information. Now, can anyone name a common microprocessor?
Intel x86 is one, I believe.
Great answer! Intel x86 and ARM Cortex are very popular. Let's summarize: microprocessors consist of an ALU, control unit, registers, and buses.

Next, letβs discuss memory interfacing. Can anybody differentiate between RAM, ROM, and Flash memory?
RAM is volatile, meaning it loses data when the power is off, while ROM is non-volatile.
Exactly! RAM is there for temporary storage, and ROM retains important data even when the device is powered down. Now, why is address decoding critical in this context?
It helps to select the correct memory device when accessing data, right?
Correct! Moving on to peripheral interfacing. Can someone explain how I/O ports work?
They allow processors to communicate with external devices!
Exactly right! And protocols like UART, SPI, and I2C help facilitate this communication. To summarize, memory types differ in volatility, and address decoding is vital for correct device selection.
