Study Notes
- Interfaces convert computer signals to match real-world signals: Amplitude, Current, Waveform, and Physical properties.
- Interface is different from peripherals (keyboard, display, mouse). Interfaces can be programmed using languages and hardware components (Arduino shields).
- Low-level programming languages: Machine language (assembly language) involves addressing codes, labels, and opcodes.
- High-level programming languages: Editors, compilers, IDEs, and opcodes. Assembly language can be translated to machine language.
- Advantages of high-level languages: Easy to understand, adjust code easily, and compiler protects hardware.
- Reasons for machine language's decline: Requires in-depth hardware knowledge, complex systems, and language and features depend on hardware.
- Interrupts are signals that pause a program's normal execution to address a specific event. They improve system responsiveness and efficiency.
- Interrupts can be hardware or software triggered, and crucial for multitasking and real-time systems.
- ARM Generic Interrupt Controller manages and prioritizes interrupts, routes them to the correct processor core, and supports various interrupt modes.
- MMU (Memory Management Unit) converts virtual memory addresses used by programs into physical addresses on the hardware.
- DMA (Direct Memory Access) allows for data transfer between devices and system memory without CPU intervention, increasing efficiency.
- RAID (Redundant Array of Independent Disks) stores data on multiple disks, offering redundancy and data recovery in case of a disk failure.
- Parallel communication transmits data to multiple devices at the same time, while serial communication sends data one bit at a time.
- Level shifters convert and adapt signal voltage levels to ensure compatibility between devices with different voltage requirements.
- In RS232 serial communication, level shifters are used to adjust signal levels between devices.
