Study Notes
Microprocessor Components
- The component not part of the CPU in a microprocessor is the memory.
Microcontroller vs Microprocessor
- A microcontroller is distinguished from a microprocessor by having internal memory and peripherals.
8051 Microcontroller
- The 8051 microcontroller has a unique feature of being 8-bit and having 4KB of on-chip program memory.
Stack Pointer (SP)
- The Stack Pointer (SP) in a microprocessor is responsible for keeping track of the top of the stack, which is a region of memory that stores data and program counters.
Memory Decoders
- The primary purpose of memory decoders in a microprocessor system is to provide a unique address to each location in memory, enabling the CPU to access the required memory location.
