What we have learnt
- Microcontrollers can have either separate I/O and memory spaces or utilize memory-mapped I/O for control registers.
- Different processor architectures include accumulator-based, register-based, stack-based, and pipeline architectures, each with distinct operational advantages and drawbacks.
- Power-saving modes are critical in microcontrollers to maximize efficiency in battery-operated devices.
Key Concepts
- -- MemoryMapped I/O
- A method where I/O control registers are mapped into the memory address space, allowing standard memory read and write instructions to access them.
- -- Accumulatorbased Architecture
- A processor architecture where operations begin and end with accumulators, typically resulting in slower performance compared to architectures using registers as operands.
- -- PowerSaving Modes
- Various operational states in microcontrollers designed to reduce power consumption without compromising functionality, like STOP CLOCK, IDLE, and POWER DOWN modes.
- -- Pipeline Architecture
- An architecture where different stages of instruction execution overlap to improve performance, allowing for an instruction to be completed with every clock cycle.
