Key Concepts
- -- AMBA (Advanced Microcontroller Bus Architecture)
- A standardized protocol defined by ARM for on-chip interconnects that allows integration of various components in embedded systems.
- -- AHBLite
- A simplified version of the AMBA AHB, designed for systems with simpler connectivity needs but requiring high performance.
- -- Bus Master & Slave
- A bus master initiates data transfers while a bus slave responds to these requests, facilitating communication in the AHB-Lite architecture.
- -- Burst Transfer
- A method that allows multiple data items to be transferred using a single address and control sequence, enhancing data transfer efficiency.
- -- Timing and Synchronization
- Crucial elements that ensure data is correctly transferred between the master and slave devices by coordinating the address and data phases.
