- **Caution**: 

### Q: What is the primary function of an Error Correction Unit in Protocol Processors?
**A**: The Error Correction Unit detects and corrects data transmission errors in real-time, ensuring data integrity and reliable communication between electronic components in computer and optical manufacturing systems.

### Q: What materials are typically used in manufacturing Error Correction Units?
**A**: Error Correction Units are primarily constructed using silicon for integrated circuits and PCB (printed circuit board) substrates, which provide the necessary electrical pathways and structural support for the correction logic components.

### Q: How does the BOM (Correction Logic, Error Locator, Syndrome Calculator) work together?
**A**: The Syndrome Calculator identifies error patterns in transmitted data, the Error Locator pinpoints the exact position of errors, and the Correction Logic applies algorithms to fix the identified errors, creating a complete error detection and correction system.
