Methods and apparatus to perform data encapsulation over serial links

An apparatus comprising:

• a first buffer configurable to store first data in a first format;
• encapsulation controller configurable to convert the first data in the first format to a second format;
• a transmitter having an input and an output, the input of the transmitter coupled to an output of the encapsulation controller, the output of the transmitter coupled to a first endpoint;
• a second buffer configurable to provide stored second data in the first format to a second endpoint;
• and
• a controller configurable to cause the first endpoint to stop sending additional data to the second buffer based on an amount of data in the second buffer being above a threshold.

A system comprising:

• sensor circuitry including an input and an output, the sensor circuitry configurable to:
• monitor an amount of data stored in a second buffer, the second buffer storing received data from a processor endpoint;
• and
• after the amount of data stored in the second buffer is above a threshold, store a pause frame into a first buffer, the first buffer storing data to be transmitted to the processor endpoint;
• and
• the processor endpoint including an input and an output, the input of the processor endpoint coupled to the output of the sensor circuitry and the output of the processor endpoint coupled to the input of the sensor circuitry, the processor endpoint configurable to:
• transmit the data to the sensor circuitry;
• and
• after receiving the pause frame from the sensor circuitry, pause transmission of the data to the sensor circuitry for a threshold amount of time.

A vehicle comprising:

• a media access control layer configurable to provide first data in a first format and receive second data in the first format;
• a first buffer configurable to store the first data from the media access control layer;
• encapsulation controller configurable to convert the first data in the first format to a second format;
• a transmitter having an input and an output, the input of the transmitter coupled to an output of the encapsulation controller;
• a second buffer configurable to provide stored data in the first format to the media access control layer, the stored data including the second data;
• and
• a controller configurable to, after an amount of data in the first buffer is above a threshold, store a pause frame in the second buffer.
