Abstract
A serial communication link receiver-transmitter with autonomous transmission error detection is described, and a communication peripherals including the same. Transmit data at a transmitter and transmitted data output by the transmitter and received by the receiver are observed by an error detector configured to generate an error indication in response to difference between the transmit data and corresponding observed transmit data of a transmitted data frame. If a difference is detected a transmit error indicator is asserted.
Claims21
A serial communication link receiver-transmitter, comprising:
- a transmitter and a receiver configured to perform data transmission and data reception, respectively, at a same side of a serial communication link;
- and
- an error detector operatively coupled to the transmitter and receiver, the error detector configured to provide a transmit error indication responsive to a difference between transmit data received at the transmitter and transmitted data output by the transmitter.
A method of detecting a transmission error in a transmitted data frame on a serial communication link, the method comprising:
- serially outputting a transmitted data frame including transmit data;
- and
- asserting an error indicator responsive to determining that an observed transmitted data is different than an observed transmit data.
A computing system, comprising:
- a processor;
- and
- a memory storage having thereon machine-executable code adapted to permanently configure logic circuitry of the processor to:
- observe a transmit data received for transmission by a transmitter of a serial communication link;
- serially output a transmit data frame including transmitted data;
- observe the transmitted data of the transmit data frame;
- and
- assert an error indicator responsive to determining that the observed transmitted data is different than an observed transmit data.
