What is advantages of MOST communication protocol over CAN in vehicle?

Advantages:

1. Higher bandwidth: MOST supports data rates of up to 25 Mbps, which is significantly higher than the 1 Mbps maximum data rate of CAN. This allows for the transmission of richer multimedia content, such as high-resolution images and videos.

2. Lower latency: MOST has a lower latency (delay) than CAN, which is important for real-time applications such as voice control and driver assistance systems.

3. More robust error detection and correction: MOST uses a cyclic redundancy check (CRC) to detect errors in transmitted data, and can use forward error correction (FEC) to correct these errors. This helps to ensure reliable communication even in noisy environments.

4. Support for multiplexing: MOST can multiplex multiple signals onto a single physical link, which saves wiring and reduces the complexity of the vehicle network.

5. Support for daisy-chaining: MOST devices can be connected in a daisy-chain configuration, which makes it easier to add or remove devices from the network.

6. Built-in support for multimedia: MOST natively supports multimedia applications, including audio, video, and graphics.

7. Improved signal integrity: MOST uses differential signaling, which helps to improve signal integrity and reduce noise interference.

8. Scalability: MOST is scalable, and can support a large number of devices on the network.

9. Lower power consumption: MOST has a lower power consumption than CAN, which is important for battery-powered devices.
