Key Concepts
- -- Bus Architecture
- The structural design of pathways within a microcomputer that allows communication between various components, influencing performance and complexity.
- -- Arithmetic Coprocessor
- A specialized processor designed to handle complex arithmetic calculations, such as floating-point operations, in conjunction with the main CPU.
- -- Address Conflict
- A scenario where multiple devices respond to the same address or overlapping addresses, leading to data corruption and system instability.
- -- Signal Conditioning
- Techniques used to ensure that electrical signals remain stable and free from interference, thereby maintaining data integrity during transmission.
- -- MemoryMapped I/O
- A method where peripheral device registers are treated as memory locations within the same address space, simplifying access but reserving part of the memory for I/O.
