Abstract
According to one embodiment, a communication system includes a host controller, a plurality of communication devices, and a communication path coupling the host controller and the communication devices in a ring shape and configured to transmit a communication frame for serial communications, wherein the host controller and the communication devices each includes an ECC circuit configured to detect and correct an error and having a variable error correction capability, and the host controller is configured to set an error correction capability of the ECC circuit in accordance with an error caused in the communication path.
Claims20
A communication system comprising:
- a host controller;
- a plurality of communication devices;
- and
- a communication path coupling the host controller and the communication devices in a ring shape and configured to transmit a communication frame for serial communications,
- wherein:
- the host controller and the communication devices each includes an ECC circuit configured to detect and correct an error and having a variable error correction capability;
